OK, so has anyone here ever had a sim card error my phone has a kinda translucent airplane mode that won't go away I can turn the airplane mode on and off and it still won't disappear like it's in my developer settings. Also ehere tbe network signal was there i stop or a no sign. A circle with a line through it. I let an at&t guy take my phone to look at it and it's been messed up ever since? Any insight to what happened will be greatly appreciated
