I have the latest build on my Lumia 925. I use Family Mobile as my service provider which uses T-Mobile towers. Has anyone heard of data issues since upgrading? My phone service works fine and I can get data via WiFi but that's it. Thanks.
Found a solution that worked for me. Went to settings and Access Point. Copied the info from the T-Mobile AP and then created a new AP called TMobile and entered in the info in the same fields. Activated the new AP, deleted the old and Voila!
