I have heard from several people that their S3's are getting a "No SIM" error randomly which disallows them to do anything with the phone. One way to correct it is try a power cycle but if not, pulling the SIM and battery for a minute seem to help. Others have said that if they just let it go, it will resolve itself after a few minutes. This is more of a probing post to find out if there are any others having this problem. It doesn't seem to be an actual SIM issue since a few people came from a previous phone using the same SIM, never had a problem on the previous phone. I am leaning towards this being a software issue since it seems to be fixable by a power cycle and/or battery/SIM pull. I bought an S3 for a backup phone to my Gnex so I havent had enough time with it yet to see if mine does this too but any and all feedback is welcome. I am just really doubting that everyone I know that has this phone, getting this error, would have a defective phone. Discuss!!
