CALLER ID

Allows you to identify the number of the person who is calling before you answer your mobile phone. You can answer with a personal greeting.

CALL WAITING

Allows you to answer a second call while another call is in progress. You can also switch between calls. Air-time charges apply to both calls.

CALL FORWARDING

This redirects your incoming calls to an alternative pre-selected phone number either permanently or when the phone is busy or not answered. Air-time charges do not apply for calls which terminate on another phone or in a Voice Mail box.

VOICE MAIL

Allows you to receive messages when your phone is busy, or if you are unable to answer the call. You can also play back messages at any time from your own mobile or from any touch-tone phone.

ROAMING

Roaming gives Mobile Customers the opportunity to Make and Receive calls outside of their home service area (the country where their mobile phone was first activated.) This service will give customers travelling to specified international destinations the ability to use their mobile phones immediately on arrival. International visitors to Trinidad and Tobago in the same way can use their mobile phones on arrival to the islands. There are two types of Roaming:

Seamless Roaming

Seamless roaming allows customers to Make and Receive calls outside their home market, once there is a Roaming Agreement between the Visited Market and the Home Market.

Unregistered Roaming

Unregistered roaming allows customers to only make calls in a visited market where there are No Roaming Agreements with their home market. Origination can either be Collect, Credit Card or Calling Card Calls.

• Please note that a TSTT mobile or landline customer calling another TSTT mobile customer who is roaming will pay for a local call only. The Roamer pays for incoming airtime and toll.
  
  
• If a foreign mobile customer is roaming in Trinidad & Tobago, and a local customer calls that Roamer, the local customer will have to pay for an overseas call.
  
  
• When a foreign customer is roaming in your market you can call a local telephone number (684-ROAM), and your call will be placed to a Roamer Port which gives you access to dial the roamer's number at the Local Airtime Charges.
  
  
• If you are roaming in a foreign city (e.g. Miami), and someone who lives in Miami wants to contact you, they can call the Roamer Port number from that serving carrier, and the call would be billed as a local call.

 

INTERPRETING BILLS

• When a customer is roaming All Calls Received are to be paid for.
  
  
• When calls are delivered to your phone whilst roaming abroad, the originating number is not normally seen on your bill. What appears is the translated international number used to set up the call delivery. This number is different for different carriers, and can also be different for calls received from the same carrier. What the customer will see on the bill next to that number is CD, meaning Call Delivery.

MOBILE NETWORKS

• Mobile Networks operate in two major frequency bands: A-band and the B-band. TSTT operates in the B-band. As a result roaming customers will have to change their units from B-band to A-band in markets where the carrier's operating frequency is the A-band.
  
  
• International Help Line Numbers 611 & *611 Customers can call these numbers when roaming. Information about a serving carrier e.g. their frequency band, their rates, the operating times of their call centers and information about their roamer ports can be obtained from dialing these numbers. Carriers also have their own hotline numbers that they give to their subscribers to contact them if problems are encountered while roaming.
