Tech Specs for Trinidad and Tobago

Created : July 7th, 2004

Introduction

This page provides information about some of the basic technical specifications and standards in use in Trinidad and Tobago. Will you be visiting Trinidad and Tobago in the near future? Will you be bringing your electronic devices (e.g. digital camera, cellphone, PDA, laptop computer, MP3 player, etc) with you? This page is for you.

Electricity

In Trinidad and Tobago, electricity is distributed by the Trinidad & Tobago Electricity Commission (T&TEC). Their official website is located at: http://www.ttec.co.tt/. According to their website, electricity is supplied:

  • at a frequency of 60 Hertz (60Hz).
  • the typical residential supply is AC, 115/230 Volt, single phase, 3 wire.

For most purposes, the electricial outlets available to the typical visitor (at hotels, guest houses, homes of relatives/friends, etc) will supply 115V/60Hz electricity.

Notes:

  • The electrical voltage can vary in the range 110V to 120V depending on time of day, load conditions, demand, etc.
  • Your electrical device should be able to operate in the 110V to 120V range.

Types of electrical plugs:

  • Flat blade attachment plug
  • Flat blades with round grounding pin

Telephones (land lines)

Land line service in Trinidad and Tobago is provided by Telecommunications Services of Trinidad and Tobago (TSTT). Their webiste is located at: http://www.tstt.co.tt. TSTT uses standards similar to those of North America:

  • Telephone outlets use the RJ-11 socket.
  • Phones, fax machines, answering machines, modems, etc. are connected to the outlet via a RJ-11 modular plug.

Cellular telephones

The local phone company, Telecommunications Services of Trinidad and Tobago, (TSTT) offers both TDMA and GSM cellular service. Reminder: Check with your cellular service provider for information about roaming rates, compatibility, etc.) before bringing your cellular phone to Trinidad and Tobago.

Further information about the GSM service can be found on our GSM in TnT page.

Television/video standards

Trinidad and Tobago uses the North American standard for television broadcasting.

  • Television/video standard: NTSC.
  • Number of lines: 525.
  • Frequency: 60Hz.

NTSC to PAL and PAL to NTSC conversions are available from local video production companies (check the local telephone directory for contact information) but can be expensive for the average visitor.

Internet Access

Dial-up access is still the most common with “broadband” available in limited areas. For general information check this page: Internet Access Options in TnT

As a visitor, you have several options by which you can access the Internet:

Hotels

The major hotels offer access in one form or the other:

  • The access can be directly from your room via a Ethernet cable or WiFi.
  • It may also be from a specially designated “computer room” where the hotel already has computers set and ready to access the Internet
  • It may also be from a specially designated “computer room” where you can plug your portable computer into a telephone jack or ethernet port.

Cybercafes

There are many cybercafes locate throughout the country, check the local telephone directory for contact information. Quality of service, speed and available equipment/applications varies from cafe to cafe.

Dial-up access

One local ISP, Opus Networx offers a “visitor account” for the duration of your stay. Check the website: http://www.opusnetworx.co.tt for further details.

619-EASY

The local phone company (TSTT) offers Internet access service without the need to sign-up for an account. Simply configure your computer to dial 619-easy (3279) and use the username EASY (use all capital letters because it is case-sensitive). There is no password. The call will cost TT 75 cents per minute (VAT inclusive) and will be billed to the phone number from which the call was made. e.g. if you make the call from telephone number 611-0001 and spend 10 minutes online, then the charge of (0.75 x 10) TT$7.50 for Internet access time will be added to the bill for phone number 611-0001. Please do not abuse the facility and leave your relatives or friends with large phone bills for Internet access time.

Freenets

There are no “freenet”-style 80211.b, 80211.g or other such public access wireless (“WiFi”) networks currently in operation (July 2004).

Computer Hardware

Hardware for PC desktop systems e.g. RAM modules, motherboards, keyboards, mice, network cards, hard drives, floppy drives, video cards, cases, cables, etc are available “off-the-shelf” from local retailers.

Hardware for Macs is not so common. However, modern desktop Macs do use some components that are common to both Macs and PCs so, to a certain, limited extent, hardware is available.

Internal hardware for laptops (PCs and Macs) is rare. These machines use proprietary form factor parts which will not be available “off-the-shelf”.

Reminder: If you are travelling with your various electronic devices (e.g. laptop computer, PDA, digital camera, MP3 player, etc) bring: your AC adapter, spare batteries and your battery charger if possible/where applicable.

Measurement Systems

Trinidad and Tobago uses the Metric system for measurement:

  • Length: millimetres, centimetres, metres, kilometres.
  • Liquids: litres.
  • Weight: grams, kilograms.
  • Speed: kilometres per hour (Km/h).

However, as a former british colony, it is not uncommon for citizens to refer to these measurements in their imperial formats, e.g. “pounds”, “miles”, “feet”, “inches”, etc. Note: the Metric system should be used for all business transactions.

Batteries

  • Carbon and alkaline batteries are commonly available in the following formats: AAA, AA, C, D.
  • “Button” batteries, such as those used in watches and calculators are available.
  • Rechargable batteries and those with exotic contents e.g. lithium are less common.

If your electronic equipment (e.g. laptop, digital camera, MP3 player, PDA) uses a battery with a proprietary form factor, it is unlikely you will be able to purchase a replacement “off-the-shelf”.

Reminder: travel with spare batteries and your battery charger if possible/where applicable.

Recordable Media

Recordable Media is available in the following formats:

  • VHS standard video tape: 120 and 160 minutes (as measured in SP recording mode). (As of 2013, this is no longer considered a common medium)
  • Compact cassettes (As of 2013, this is no longer considered a common medium).
  • CD-R(ecordable): 650MB and 700MB are common.
  • CD-R specifically for audio is also available (but more expensive than “data” CD-Rs).
  • CR-RW (CD-rewritable) is available.
  • Recordable 4.7GB DVDs are available. Formats include: DVD-R, DVD-RW, DVD+R, DVD+RW.

Local Radio Stations

Local radio stations use the North American standard for frequency allocation:

  • The AM band uses 540 Khz to 1600Khz.
  • The FM band uses 88Mhz to 108Mhz.

There are two AM stations: 610 (state owned/operated) and 730 (privately owned/operated).

There are fifteen FM stations: 90.1, 92, 93, 94.1, 95.1, 96.1,
97, 98.1, 100, 101, 102, 103, 104, 105, 106.

Programming content includes: news, community announcements, local music, caribbean music, east-indian music, foreign pop music, hip-hop, talk radio, religious music and talk, easy listening and “golden-oldies”.

Local Television Stations

The 4 local television stations use the North American standard for frequency allocation:

  • Trinidad and Tobago Televsion (TTT): state owned/operated. VHF Channel 2 (in Trinidad) and VHF channel 13 (some parts of northern Trinindad and all of Tobago)
  • The Information Channel (TIC): state owned/operated. VFH Channel 4 (in Trinidad) and VHF channel 16 (some parts of northern Trinidad and all of Tobago)
  • CCN-TV6: privately owned/operated. VHF Channel 6 (in Trinidad), UHF channel 18 (some parts of northern Trinindad and all of Tobago), UHF channel 19 (only in Tobago).
  • Gayelle TV: privately owned/operated. UHF Channel 23. This is a “community” channel located in north western Trinidad. Other parts of the Trinidad and and all of Tobago may not receive this broadcast signal.

These stations operate “over the air” on standard VHF and UHF broadcast frequencies. They are also available (unscrambled) on the local cable television system (CCTT) in Trinidad: TTT can be found on channel 3, TIC can be found on channel 4, TV6 can be found on channel 5, Gayelle on channel 7.

The IEEE 1394 Standard

The IEEE 1394 Standard was originally created as a replacement for the SCSI interface. Three versions of the IEEE 1394 Standard have been approved by the Institute of Electrical and Electronics Engineers (IEEE):

  • 1394-1995:The original concept for a high-speed serial interface was conceived by Apple and the final Standard, 1394-1995, is based on Apple developed technology. The interface has the following capabilities:
    • Data transfer rates of up to 400 Mbps.
    • Bi-directional transfers.
    • High speed data transfer.
    • “Hot plug” connectivity (equipment using the interface can be connected and disconnected while the computer is powered on).
    • Digital interface.
    • A maximum cable length of 4.5 metres.
  • 1394a:Was finalised/adopted in 2000. It provided specifications for enhanced performance and power management on the FireWire bus.
  • 1394b:Was finalised/adopted in 2002. It supports a theoretical maximum speed of up to 3.2 Gbps at distances of up to 100 metres. It allows new types of media to be used for FireWire connections (e.g. fibre optic cabling). Continue reading The IEEE 1394 Standard

GSM in TnT | [05-jul-2004]

GSM in TnT

updated : 05 July 2004

Introduction

This page is about the GSM cellular telephone service offered by TSTT to citizens of Trinidad and Tobago.

GSM is the: Global System for Mobile Communications. It is a next generation telecommunications service that offers capabilities beyond the traditional voice and text of exisiting cellular services. TSTT is marketing the service under the brand name: “mpower”.

Note: the Trinidad and Tobago Computer Society (TTCS) is unable to answer questions about services in other countries.

What are the features of GSM?

GSM offers the same features as the existing TDMA system :

  • Voice calls
  • Call waiting
  • Call hold
  • Call forwarding
  • Caller ID
  • SMS (short messaging service)
  • Per second billing (TSTT will not round the call time up to the nearest minute).
  • Voice Mail (a fee will be applied for playing-back recorded messages while roaming).

In addition to these features:

  • “Call barring of incoming calls while roaming” (block incoming calls while roaming).
  • Ability to roam, that is, use GSM networks outside of Trinidad and Tobago. See this section of the FAQ (Frequently Asked Questions) section for more information about roaming.
  • Data Services The original GSM specification has a data transfer rate of 9.6K. Technologies such as GPRS (general packet radio service) have increased those transfer rates to allow users to browse the Internet, send/receive e-mail. In the near future, users will also be able to take advantage of multimedia services such as streaming audio and video.
  • WAP Internet access. (not available from TSTT at this time)

Data Services, including Internet access, are currently under trial and have not been officially launched at this time (early July 2004). The Services should be launched towards the end of July 2004. Further information about data services can be found at this link.

Where can I roam with my TSTT-based GSM phone?

The ability to roam with a TSTT-based GSM phone is dependant upon these factors:

  • The GSM frequencies supported by your phone. The TSTT system uses 1800MHz (1.8GHz). If you travel frequently to different areas of the globe then a tri-band phone would be a better investment. See the FAQ (Frequently Asked Questions) section for more information about tri-band phones.
  • Whether or not TSTT has a roaming agreement with the network operator that provides GSM service in the area where you wish to roam. The roaming agreement provides for user authentication, billing procedures and service charges. See the FAQ (Frequently Asked Questions) section for more information about roaming.

Reminder: roaming with a cellular phone (either TDMA or GSM) is expensive.

    Will existing (TDMA) cellular phones continue to work now that TSTT operates a GSM service?

    TSTT has stated that it will continue to maintain/support the existing (TDMA) cellular network. However, as of Monday 17th May 2004, TSTT no longer activates TDMA phones for post-paid (“Connect”) service but existing “Connect” customers will continue to receive service. TSTT will continue to activate pre-paid TDMA (“Liberty”) phones. If you want to be on a post-paid plan, you will now have to purchase a GSM phone and sign up for one of the GSM packages. See these sections for more information:

    Can my (USA/Canada/European/Asian/”foreign”) GSM cellular phone work on the TSTT GSM system?

    It should be able to work on the TSTT system as long as it can use the 1800Mhz frequency. However, the ability to use your “foreign” phone and the features available to you while in Trinidad and Tobago will be determined by the roaming agreement between TSTT and the network operator that services the area where you normally use your phone. The roaming agreement provides for user authentication, billing procedures and service charges.

    Contact the cellular/network operator who currently provides you with GSM services. This network operator is the entity responsible for making the roaming agreement and will be able to tell you:

    • Where (geographic location) you can roam with your phone. For example, if you can roam with your phone in Trinidad and Tobago.
    • If your phone/handset is compatible with those foreign systems.
    • Which network and/or card-enabled features will be available to you while you roam.
    • The rates for roaming.
    • The billing procedures for roaming.
    • If the roaming is “seamless” or “unregistered”. See the FAQ (Frequently Asked Questions) section for more information about roaming.

    What models/brands of cellular phones will work on TSTT’s GSM system?

    Any GSM cellular phone that can use the 1800Mhz frequency should be able to work on the TSTT system. However, you should check with TSTT before purchasing that “used”/”pre-owned” phone. If you decide to switch from TDMA to GSM, there are a variety (in terms of features and cost) of GSM phones available from the popular brands e.g. Motorola and Nokia. At the present time GSM handsets and service plans are more expensive than TDMA handsets and service plans in Trinidad and Tobago.

    TSTT is offering the following Nokia handsets with its various GSM service plans :

    • Nokia 2100
    • Nokia 3310
    • Nokia 3410
    • Nokia 3510
    • Nokia 5100
    • Nokia 5210
    • Nokia 6310i
    • Nokia 6510
    • Nokia 6610
    • Nokia 7210
    • Nokia 7650
    • Nokia 8310
    • Nokia Communicator 9210i

    Further details about the Nokia phones on this list can be found at the official Nokia website: http://www.nokiausa.com/.

    TSTT is offering the following Motorola handsets with its various GSM service plans:

    • Samsung R220

    TSTT is offering the following Sony-Ericsson handsets with its various GSM service plans:

    • Sony-Ericsson T202
    • Sony-Ericsson T68i

    As always, contact TSTT for further information on cost, availability, different brands of phones, etc.

    Will TSTT provide Subscriber Identity Modules (SIMs) for the GSM phones?

    TSTT will provide Subscriber Identity Modules (SIMs) (See: What are SIMs?) for the phones that are bundled with its various GSM service plans. In general, SIMs will be issued with the purchase of a handset. You will be able to purchase additional SIMs without having to purchase a handset.

    SIM configuration: TSTT will provide the SIM configuration in order to identify TSTT specific customers as well as enable various services for the local network. See the What models/brands of cellular phones will work on TSTT’s GSM system? section for a list of GSM phones being provided by TSTT.

    Activating non-TSTT SIMs

    • TSTT has stated that it cannot activate a foreign SIM card.
    • TSTT has stated that its GSM services cannot be activated on SIMs from a foreign provider.

    About “locked” phones

    • Handsets sold by TSTT will be “SIM-locked” and therefore will only work with TSTT SIMs.
    • If you have a (new/used) GSM phone from (USA/Canada/Europe/Asia/”foreign”) and it is “SIM-locked” to a foreign operator’s network, that phone/handset will not work with TSTT SIM cards. See: What are SIMs? and What is “SIM lock”?.
    • Note to visitors from (USA/Canada/Europe/Asia/”foreign”): The SIM provided by YOUR network operator will continue to work in YOUR phone when you roam in Trinidad and Tobago. However, if your phone is “SIM-locked”, you will not be able to use a TSTT SIM card in that phone.
    • The creator(s) of this page cannot provide any sort of help/instructions on how to unlock “SIM-locked” or any other sort of “locked” GSM phones! Do not ask for such instructions.
    • The creator(s) of this page cannot provide any sort of help/instructions on how to unlock “locked” TDMA phones!

    I am from (USA/Canada/Europe/Asia/”foreign”) and I want to use my GSM cellular phone on the TSTT GSM system

    You must first contact the cellular/network operator who currently provides you with GSM services. The network operator will be able to provide you with the relevant details about roaming especially where (geographic location) you can roam with your phone. You can also consult the following sections on this page:

    I want to purchase my GSM cellular phone from (USA/Canada/Europe/Asia/”foreign”) and use it on the TSTT GSM system

    If you want to purchase a GSM cellular phone from (USA/Canada/Europe/Asia/”foreign”), it must meet these specifications:

    • It must be able to operate on the 1800MHz (1.8GHz) frequency.
    • It must not be “SIM-locked” to a foreign operator’s network. If the phone/handset is locked, it will not work with TSTT SIM cards. See: What are SIMs? and What is “SIM lock”?.

    Other factors to take into consideration:

    • Do not purchase SIMs from outside of Trinidad and Tobago for use on the TSTT GSM network. See: Activating non-TSTT SIMs.
    • If you travel frequently and wish to roam with your GSM phone then you may want to purchase a tri-band phone. See the FAQ (Frequently Asked Questions) section for more information about tri-band phones.
    • If you wish to use the GSM data services (e.g. GPRS), make sure the particular phone model has that capability.
    • Know what you are purchasing! Less expensive GSM phones tend to be limited to voice and text messaging and do not have data capability.
    • SIM-locked phones restrict you to a particular cellular network. Lock-free phones (that is, phones which are not SIM-locked at the factory) allow you to use any SIM from any GSM provider anywhere in the world.

    FAQ (Frequently Asked Questions)

    • What is dual band?Dual band refers to the ability of GSM network infrastructure and phones to operate across two frequency bands. For example at 900MHz and at 1800MHz.
    • What is a tri-band phone?A tri-band cellular phone has the ability to operate on the 3 different frequencies (depending on location) commonly used by GSM operators. These GSM frequencies are: 900MHz, 1800MHz and 1900MHz.
    • What is a dual mode phone?A dual mode cellular phone has the ability to operate in either analog or digital mode depending on network conditions. This description is exclusive to TDMA phones since the GSM system is one hundred percent digital. TSTT has discontinued analog TDMA service.
    • Can my existing (TDMA) cellular phone work on the TSTT GSM system?No, because TDMA cellular phones are incompatible with the GSM system.
    • What is GPRS?GPRS is the GSM Packet Radio Service. Packet switching utilises the network only when there is data to be sent as opposed to sending a continuous stream of data over a permanent connection. Users are able to send and receive data at speeds of up to (a theoretical maximum) of 115Kbit/s. GPRS enables users to connect to a wide range of public and private data networks which use standard data protocols such as TCP/IP and make
      use of applications such as email or Internet (WWW) access.
    • What are SIMs?What are “Smart” cards?Subscriber Identity Module (SIM) cards are used to provide individual identities for each mobile user: e.g. authentication and storage for user data and network configuration information. The current generation of SIMs (“Smart” cards) contain microchips which extend the “intelligence” and capability of the card. Users are now able to access a vast range of card-enabled (as opposed to network-enabled) applications. The SIM must be inserted in the phone for the user to make and receive calls.
    • What is “SIM lock”? “SIM lock” is the term used to describe the pre-programming of handsets by manufacturers to ensure that the handsets will only work with SIMs issued by a specific GSM network operator. For example: TSTT has stated that it will be selling SIM-locked phones. This means that if you try to use a non-TSTT SIM, the phone will not work. See: What are SIMs?
    • What is “roaming”? Roaming is the ability for a cellular customer to make and receive voice calls, send and receive data, etc on “visited” networks, that is, GSM networks located outside the geographical coverage area of their home network. These “visited” networks can be accessed in the same manner as the home network. For example, a TSTT customer (with a GSM phone) is able to make and receive voice calls while travelling in Europe (an example of international/global roaming). There are 3 types of roaming:
      • National Roaming: The visited network is in the same country as the home network.
      • International Roaming or Global Roaming: The visited network is outside the home country.
      • Inter-standard roaming: The visited network operates on a different technical standard than the home network.
    • What is “seamless roaming”?Seamless roaming allows cellular customers to make and receive calls on “visited” networks, as long as there is a roaming agreement between the operator of the “visited” network and the operator of their “home” network.
    • What is “unregistered roaming”?Unregistered roaming allows cellular customers to make (originate) calls on “visited” networks where there are NO roaming agreements between the operator of the “visited” network and the operator of their “home” network. Calls are billed via one of these methods: Collect, Credit Card or Calling Card. Calls which originate via unregistered roaming are usually more expensive than calls which originate via seamless roaming. TSTT does not officially support unregistered roaming at this time (July 2004).

    Telecommunications (Amendment) Act, 2004

    The Telecommunications (Amendment) Bill 2004 was introduced in the House of Representatives in March 2004. The introductory text of the Bill states :

    “These amendments to the Telecommunications Act 2001 purport, inter alia, to bring clarity to provisions considered ambiguous, to encourage investment by creating and sustaining a framework for fair competition and to ensure the availability of quality services at affordable prices; all of the foregoing being required by the International Telecommunications Union and the World Trade Organisation in respect of legislative reform in the telecommunications/ICT industry.”

    The Explanatory Notes for modifying the definition of “public telephone service” “..will make it abundantly clear that the Authority will regulate the delivery of all public voice services irrespective of the means used to provide the service (e.g., VOIP)”

    Page 3 of the Explanatory Notes for the definition of “value added service” states that : “The existing definition creates ambiguity with respect to the classification of ISPs. Government’s policy requires the regulation of ISPs as public data telecommunications service providers. The revised definition (of value added services) is in accordance with this policy prescription as the definition makes it clearer that value added services are services that provide content and shall not include services by which such content is provided. ……

    Various comments/opinions of the Telecommunication (Amendment) Bill :

    The Telecommunications Amendment Bill, 2004 was passed in the House of Representatives on the 20th April, 2004. It was passed in the Senate with amendments on 18th May 2004. The House of Representatives approved the Senate Amendments on the 26 May 2004. It was assented to on June 14th, 2004.

    SMS in TnT | [05-jun-2004]

    SMS in TnT

    updated : 05 June 2004

    Introduction

    SMS or Short Message Service, (also known as short messaging service, text messaging, mobile messaging, or alphanumeric paging, celltext, texting, phone messaging) enables you to send brief text/numeric messages to and from digital cellular telephones. Messages can originate from cell phones as well as e-mail addresses and public SMS gateways on the Internet. Telecommunications Services of Trinidad and Tobago (TSTT) is offering the service under the brand name “TSTT Lingo”.

    The Trinidad and Tobago Computer Society (TTCS) is unable to answer questions about services, cellphones, etc offered/available in other countries.

    What are the benefits of SMS?

    Messages can be received while making voice calls, there are no busy signals to contend with, it is silent and discreet (unless you have one of the many annoying alert tones enabled!). Messages generated by SMS are delivered immediately and directly to your phone, there is no need to call an access number or enter/remember a password to retrieve it (as must be done with voice-mail).

    In Trinidad and Tobago, users of the pre-paid services (both “Liberty” for the TDMA and pre-paid Mpower GSM) have found that brief messages sent via SMS are cheaper than making a voice calls to “send” the same information.

    SMS messages are sent to and processed by a Short Message Service Centre, which then delivers the message to the recipient’s phone. If the phone is turned off, the service centre will store the message and attempt to re-deliver it for a period of 3 to 7 days. The actual time is dependant upon the service provider (TSTT).

    What is the difference between SMS, Instant Messaging Service (IMS), and E-mail?

    E-mail and SMS are both “store and forward” systems that utilize a “gateway” to pass messages from senders to recipients, however, the obvious difference between the two are the length/complexity of the messages that can be sent on the respective systems. The maximim size of a SMS message is usually 160 characters (actual size is dependant on the service provider). The messages are limited to text and numeral characters. Graphics, colour, HTML formatting and file attachments are not allowed.

    On the other hand, e-mail can contain thousands of characters and allows the use of HTML formatting, files to be attached and images to be embedded within the message . Instant Messaging Service (IMS), (e.g. AOL Instant Messenger “AIM”, ICQ, MSN Messenger and Yahoo Messenger) allows you to conduct real-time text conversations (“chat”) with people who are simultaneously connected to the Internet and, in some cases, allow the transfer of files. SMS messages are immediate, but not simultaneous.

    How do you send and receive SMS messages?

    Receiving messages is easy. Most phones will display an incoming message alert graphic on the screen. You may also set a tone to sound when incoming messages are received. Once a message is received, you can use the scroll keys on your phone to view the content of the message. Options to store, reply, or forward each message will be available at that time. The exact procedure to send a message varies from device to device, but it usually involves entering the recipient’s phone number or e-mail address, and then composing the message with the phone keypad. You may have the option to send the message instantly or store it for later delivery. Check the user’s manual for the specific details on how to access these features on your particular brand/model of cell phone.

    How do you use public gateways to send messages?

    Cellular service providers who offer SMS usually offer public SMS gateways, which allow you to compose and send messages from the service provider’s web site. TSTT does not offer such a service from/on any of its websites at this time. A number of independently operated message gateways also exist on the Internet. These public gateways are usually available from any computer with Internet access. Examples of locally operated gateways can be found at:

    Update: According to a news report (Sunday Guardian: 14th December 2003 page 3 and Sunday Newsday: 14th December 2003 page 8) TSTT will begin to charge for receiving SMS messages sent from the Internet in April 2004. How will this affect the public SMS gateways? We do not know but most likely they will have to shut down.

    Update 2: May 2004: TSTT has not implemented any charges for receiving SMS messages sent from the Internet at this time.

    What are the fees for the TSTT Short Message Service?

    Some information in this section is based on a TSTT advertisment in the Trinidad Guardian newspaper (Sunday 9th November 2003 pg 61)

    How to send a message via SMS on the TSTT system

    Some information in this section is based on an official TSTT advertisment in the Trinidad Guardian newspaper (dated Monday 4th March 2002 page 15)

    There are three ways to send messages via SMS:

    • To send a Short Message using Internet-based email, the message must be addressed to: 868#######@tsttmobile.co.tt (where ####### = the cell number of the person receiving the message). The email must conform to SMS message specifications
    • To send a Short Message using a local public gateway, use these links and follow all instructions:
    • To send a Short Message using your cellular telephone, the message must be addressed to: 868####### (where ####### = the cell number of the person receiving the message). The exact procedure to send a message from one cell phone to another cell phone varies from device to device, but it usually involves entering the recipient’s phone number and then composing the message with the phone keypad. Check the user’s manual for the specific details on how to access these features on your particular brand/model of cell phone.

    Notes:

    • Check your retailer to make sure your new phone supports sms before purchasing it!
    • If your phone model/manufacturer is not listed here, check your user’s manual to make sure it supports these features.
    • All sms options supported by these units may not be available on the TSTT system.
    • Check the users manual for further info on how to use these features on your phone.
    • Contact TSTT at: 824-TSTT(8788) if you require more information on the features, availability, restrictions, requirements, fees, etc associated with this service.

    SMS message specifications

    Your SMS message must meet the following specifications in order to be sent and received successfully:

    • Maximum size of the message: 160 characters (punctuation marks AND spaces are counted as characters).
    • Messages have to be in plain text. SMS does not support HTML formatting. In other words, it won’t look like a web page and you can’t see colours, graphics or those email “wallpapers”. Outlook/Outlook Express users take note! You may have to check your software settings/options/configuration and switch off HTML formatting.
    • You cannot send any sort of file attachments e.g. zip, mp3, mpeg, mpg, avi, doc, xls on the SMS system.

    SMS Etiquette

    • Turn down the volume of your alert tone. YOU need to know you received a message. No one else does.
    • Keep your subject line brief. The characters in the subject count towards your total of 160. Better yet, do not use a subject line that way you can maximise the content of your message.
    • Messages must be read on cell phone screens so keep your message brief.
    • Don’t send a “signature”, a tagline, inspirational quote or any other unnecessary material with your message. Remember, there is a character limit so your message will be truncated if it exceeds that limit.
    • Avoid unnecessary spaces in the message. Spaces count towards your total of 160 characters.

    The SMS (Short Message Service) Dictionary

    SMS supports a limited number of characters per text message (approx. 160) so here’s a list of abbreviations and emoticons to help create that message.

    FAQ (Frequently Asked Questions)

    • Who can I contact at TSTT for further information?The contact number given in a TSTT advertisment is: 824-TSTT(8788).
    • Can you tell me if brand X, model y is sms capable?If it is not on the list, then no. Read your user’s manual and/or check the manufacturer’s website for further information.
    • You keep telling me to “read the user’s manual” but I don’t have one! Where can I get one?The manufacturer of your cell phone should have an electronic version of the manual available for download (usually a Word .doc file or an Acrobat .pdf file) from their official website. Nokia and Motorola offer such a service.
    • Why is there a limit of 160 characters?This is due to the limits of the SMS specification as well as the system in use by the SMS provider.
    • Can my phone be “upgraded” (via hardware or software) to support SMS?If the manufacturer did not include the capability then you either have to live without it or buy a new phone with SMS support. It cannot be upgraded.
    • Can I use SMS to download new ringtones to my phone?Yes,but your phone (brand/model) must support the ability to change ringtones (check the user’s manual for the specific details). At this time (June 2004) TSTT does not offer this feature. The TTCS also has a separate page to provide details about (Nokia) ringtones at this URL: http://www.ttcsweb.org/articles/nringtones/.
    • How do I change the “message received” alert tone for my phone?Check the user’s manual for the specific details on how to access these features on your particular brand/model of cell phone.
    • Why must I change the settings in Outlook/Outlook Express?These email clients send HTML formatted email by default. HTML is the “language” used to create web pages. SMS does not support HTML formatting. So if you want to use these clients to send SMS messages you have to turn off HTML formatting and send it in plain text.
    • I used the SMS gateway site(s) mentioned on this page but my message was not sent or I got an error message. What’s wrong with the gateway?These gateways must interface with TSTT so whenever the TSTT system is down, the gateway sites cannot transfer your message. The operators of the gateway site(s) have no control over the availability or reliability of the TSTT SMS service.
    • Is SMS the same as email?No.
    • Can I send SMS messages from the network in my office?Only if your network has Internet access and only if the system adminstrator allows it.
    • Can I send SMS messages from my TSTT cellphone to a cellphone on a foreign network in another country?No. At this time, you cannot send a SMS message from a cellphone on the TSTT cellular system (either TDMA or GSM) to a cellphone on an overseas (TDMA, GSM or PCS) network.
    • Can I send SMS messages from a cellphone on a TDMA network to a cellphone on a GSM or PCS network?Yes, but only because the networks are operated by the same carrier. In Trinidad and Tobago, TSTT operates both TDMA and GSM networks. Therefore it is possible to send a SMS message from a cellphone on the TDMA network to a cellphone on the GSM network and vice versa.
    • If I “roam” abroad with my TSTT cellphone, can I still send/receive SMS messages?Only if the following conditions are met:
      • You are using a GSM phone from TSTT
      • TSTT has a roaming agreement with network operator(s) in the country where you are roaming.
      • You are using a TSTT SIM-card in your phone.

      You will not be able to send/receive SMS messages if you are using a non-TSTT SIM. The TTCS page about GSM service in Trinidad and Tobago provides a list of coutries where TSTT GSM customers can roam and send/receive SMS messages.

    • How do I send SMS messages to cellphones in other countries?You will have to investigate this on your own since it will be country/SMS-provider specific. It is possible that there is an internet-email to SMS facility or a SMS gateway you can use to send such messages. Ask the intended recipient to do some research for you. If you want to share the information then email us: ttcs@opus.co.tt
    • Can someone from another country send SMS messages to me?Yes. They can use the email method or log onto one of the local sms gateways and send you a message. Remember
      , they have to know the number of your cellular telephone! Check this section for details.
    • Will SMS work on my GSM phone?Will the local SMS gateways be able to send messages to my GSM phone?Yes. Further information about the TSTT GSM system can be found here: www.ttcsweb.org/articles/gsm/.
    • I don’t want this service . . . Can I switch it off?Once the cellphone provider has switched on the service and your phone is SMS capable, it will automatically receive messages addressed to it. However, (according to an official TSTT advertisment in the Trinidad Guardian newspaper, Thursday 7th March 2002, page 15) TSTT cellular customers can contact TSTT to have the service discontinued. The contact number given in the advertisment is: 824-TSTT(8788).
    • Is there any way to block someone from sending SMS messages to my phone?The only definite way to block messages to your phone is to contact TSTT (at 824-8788) and have the service discontinued, unfortunately, this would mean all SMS service/features, not just the nuisance messages, would be blocked.
    • How long has SMS been officially available on the local cellular network?TSTT officially launched the service to the public under the brand name “TSTT Lingo” on Monday 4th march 2002.
    • Where did you get all of this information? Do you work for TSTT?The creator(s) of this page and the TTCS are not affiliated with Telecommunications Services of Trinidad and Tobago (TSTT). All information on this page was gathered from public sources. No one invoved in the creation and maintainence of this page is employed by TSTT.
    • How long has this SMS page been online?This SMS page has been online ever since TSTT started testing the service in the last quarter of 2001.

    Troubleshooting Tips

    • Why can’t I receive messages?
      • Is your phone capable of receiving SMS? Some older phones cannot receive sms. Check your users manual.
      • Was it sent properly? review the send messages via SMS section and SMS message specifications to make sure.
      • Did the sender include some sort of attachment or HTML formatting that could “confuse” the SMS gateway?
      • Is it a used phone? Did the previous owner have the service switched off?
    • Why is the message cut off half way through the text?Why did I receive only part of the message? This will happen if the sender did not restrict the message to 160 characters!
    • Why can’t I send messages?
      • Is your phone capable of sending messages? Some older phones cannot transmit sms. Check your users manual.
      • Was it formatted properly? review the send messages via SMS and SMS message specifications to make sure.
