Call Back allows users to make international calls at competitive rates simply by either sending an SMS or by dialing an access number and waiting for your phone to "Call Back". It's that easy. Simply send and SMS or dial the access number, let it ring at least two times and hang up. GTI's network will call you back within seconds and then you simply dial the international destination you desire. You can use your home, office or mobile as long as caller ID is available for that line.

The Call Back Service is available in the following denominations
USD 25		USD 50
USD 100

After payment you will receive a notification by email instructing you how to use the service and how to access your online account information.

Thank you for choosing GTI.
