    My samsung galaxy s2 has no signal

    Hello, my samsung galaxy s2 at&t sgh i777 has no signal for some reason. I've switched sim card with another phone and it works, so it must be the phone. It was doing just fine for a few weeks, then all of a sudden no signal. I've factory resetted, it works for a few calls, then no signal now for the whole day. Do you guys know what to do?

    Sometimes it shows that i have a bars of connectivity, but when i call, no ring tone, when i try to send text messages, it sends for so long and comes back saying unable to send message.

    Is the phone stock or modified in any way?

    If you aren't having any tower issues with your other phone I would suggest flashing the stock firmware. You could also just try flashing the modem to see if your modem package is corrupt.
