I have a blackberry storm running on tmobile..A few days ago my data service stopped working, when I tried to send a text or use the browser I would get an sos signal so I called tmobile and these are the steps they gave me to fix it. THEY DID NOT WORK FOR ME...BUT they might work for some people.

To switch to GSM / EDGE from the default setting of 1X/EVDO, proceed as follows:

Then go to and tap Mobile Network.
Tap Network Technology.
Next to Network Technology change the option from global or any other setting to GSM / UMTS.
Next to Network Mode change the option to 2G.
Register the device and initiate the download of service books:

Scroll to and select Options.
Select Advanced Options.
Select Host Routing Table.
Press the Menu key.
