So, my Verizon SG3 is rooted and was running Cyanogen 10 nightly for the past few days, then today I loaded and tried to run MIUI. However, when it loaded everything up, it couldn't activate, and it said that I wasn't on a network. I've tried restoring back to Cyanogen 10 but still, it says that I'm in a roaming network. Is this a problem with a ROM, or with my SIM card? My first guess is sim, but it only started after I flashed MIUI for the first time. If it's a rom issue, any idea how to fix it?
