I have a Samsung Galaxy J7. I've had it for a couple years now with no issues. Now, I am getting an Invalid SIM Card error and its not letting me make calls, receive calls, send messages or receive them. I tried to take the card out and put it back in, as well as restarting the phone, and doing a factory reset to no avail. Please help?
