[Q] Sporadic Service Problems
I have a GS2 running Cyanogemod 10.1.2 (Android 4.2.2) on AT&T. The main issue I have is that of the service for calling/texting being extremely sporadic (as in, most of the time, it either doesn't have service at all or says it has service, but is unable to do anything). I gets texts hours after the person sent them, and I miss almost all calls.
It's not just an issue of spotty service or a messed up SIM card, since I can put the card into my other phone and is works perfectly. It's also probably not a radio issue, since WiFi is unaffected and I've reflashed a few different radios a few different times.
I've also tried just restoring an old backup or two, reinstalling an older version of Cyanogemod, and messing with the APN's (which, as far as I've been able to find online, are at the correct settings).
Rebooting and turning off WiFi sometimes seem to help, but I haven't found any consistent pattern with that.
Does anybody know what's going on?
