How it happened: I bought this just recently. I tested the unit before buying it. There were no problems with the all features. I even connected to a wifi network using my tablet's tether network, but with no internet, just to see if the wifi works. It was fine so I bought it and performed a factory reset inside settings. After I got home, I connected to my wifi network with internet, then the "Please call me" screen appears.
Solutions I've tried:
I've tried another factory reset and wiping the cache using the recovery menu (power + home + volume up). When I rebooted, it's still the same.
Any ideas? I haven't tried flashing the rom yet.
