    I have a galaxy s7 that updated this morning. After the update i'm getting the "invalid SIM card" message. Restarting the phone didn't help. Taking the SIM card out and reinserting only worked for a minute or so then the message popped up again. Is there any way to fix this that doesn't involve a factory reset? Please help!
