I unlocked my T-Mobile G2 successfully and took it to AT&T to get on the Go Plan.. The sales rep put in the sim card, money into my account and my call and text is good to go.. however there is no data at all.. I called AT&T CS and they gave me APN settings but still no data.. Ive seen people say they have LTE working on the same set up.. Any advice? Would flashing a stock AT&T G2 Rom work or would i get bricked?
Seems like the phone is compatible and uses similar bands.. At this point I don't care if it is 3G, 4G or LTE.. I just need data lol..
You are describing the exact issue my bud had when he went to cricket. No Data Service. He called cricket and download a small package they sent through sms and then had him respond to the text with a pin. Fixed him right up. Call your service provider and explain the whole no Data issue.
Also, I don't know how you unlocked it, but if you used a method where you copied over files then that may be the problem.
I had a sprint G2 along with my TMO G2. With the sprint one I put a custom Firmware TMO base on there and it worked fantastic really glad someone made a sprint firmware that could support TMO. If you haven't tried this type of method I would. That could solve the problem.
