mobile

I have the AT&T G2, rooted and Unlocked. Currently running kitkat via Cloudy G2 2.2 and have TWRP. I bought the phone to use with BYO Wireless, a prepaid company and all went well. I stuck the SIM in and activated it; there wasn't a problem. Until I realized that I couldn't receive any texts! I can call and be called, can send SMS and MMS, and data is fine as far as I can tell. The one, consistent problem over every ROM I've tried including reverting to stock is the lack of SMS on the receiving side.

I read online to try and put it in another GSM phone but the only one I could find said "Invalid SIM", it was an old Blackberry.

I've already tried taking it out and powering the phone down for a while, which only solved the issue where the SIM wasn't detected.
