Unlocked S7 Edge (US Version) Issue

[Eddster]

About 2 days ago my unlocked S7 Edge started acting really crazy. I'm using my AT&T sim and it just keeps flashing the "LTE" symbol even on wifi and it gets almost no cellular signal (not even one full bar) and speedtest is very poor. At first I thought AT&T might be having issues so I took out my sim and popped it into my Nexus 6. It worked just fine. Full LTE signal strength and speedtest was in the normal (fast) range. Put the sim back in the S7 Edge and same thing. I've reset all the connections to factory default. This is driving me crazy. I just bought this phone from Best Buy at the end of October. Any suggestions?

You might try registering your new phone's IMEI number with AT&T.

I ended up just doing a factory reset. That seems to have fixed the problem. Everything seems back to normal.

And the problem is back again. It's also causing the battery to drain very fast. UGH!!

I bought one of these to replace my broken S7 Edge and I'm using it on T-Mobile with no problems. There could be something wrong hardware wise with that phone. Try calling AT&T with the IMEI # before you try anything else though as suggested above.
