What can I do if my device does not connect to the T-Mobile GPRS/EDGE data network? (BlackBerry®)
To send or receive e-mail and have other forms of Internet access, your device must fully connect to the T-Mobile data network, which is referred to as a GPRS/EDGE network.
If you do not see the uppercase GPRS indicator or EDGE indicator on-screen, refer to the following links:

Performing a manual network selection

If you are roaming on a non-T-Mobile network, it might not offer GPRS or EDGE for your device. In this case, you should perform a manual network selection to register to the T-Mobile network or a T-Mobile roaming partner that offers GPRS or EDGE.
To perform a manual network selection, perform the following steps:
1. Consult your device's user guide for instructions on how to perform a manual network selection, or search T-Mobile Support for an article with information on how to do so.
NOTE: To search T-Mobile Support, in the search bar, enter How to perform a manual network selection - device make / model.
2. After several seconds, verify that GPRS or EDGE appears.
NOTE: GSM appears first, then gprs, then GPRS, and then EDGE if the network in your area is EDGE-capable.
3. Attempt to send or receive e-mail.
NOTE: If the steps above do not resolve your issue, go to Contact Us.
