I have been using my unlocked for Tmobile phone just fine for a while now. I was doing the pay by month thing. Now I decided to go to a full plan and now I get a message saying that data service is required. I am paying for unlimited everything. Any help on this would be great. Thanks
You have to set the data service up on the iphone cause its not tmobile... So go settings/general/network/Cellular data network and under apn type in wap.voicetream.com and you should be good if you want mms to work google tmobile mms settings to find out what to put in the mms settings. Or you can just call tmobile they will honest to god help set up your phone no questions asked.
That's all I did try turning ur phone off and back on or like I said give them a call they will get u straighten out
