Lumia 920 no service? HELP!

[xdasilvax18]

Hey guys,
so up until last week, my Lumia 920 (US, AT&T) was running perfectly, with no complaints at all. All of a sudden, my signal dropped to no service. I did not see this as much of a problem, so i soft-rebooted the phone. When it started back up, i was greeted with no service again. I waited it out. About a half hour later i was back up to my normal 4G LTE. About 5 minutes later, it dropped back down to no service. It has been repeating this cycle for over a week now and it is really really annoying. Do you think this could be an antenna problem? because i would like to address this issue myself.
Thanks.

How long have you had your phone, perhaps try and pull sim card out and wipe it off see if helps any.

A few months, but the SIM is a couple years old. I already tried removing and cleaning it with no luck.

My suggestion would be to replace the sim card give AT&T a call and have them replace it see if that fixes it.
