Anyone else's iphone x having trouble reading there sim card? My sim card never had issues in my S8 and was working fine in my Iphone X for the past week. Suddenly i keep getting a pop up that says invalid sim / sim card failure? If i remove the sim card and then put it back in then everything is fine for a while but an hour or two later the same message pops up! U updated my phone to 11.2.1 today in the hope it might be software related and the new update might fix this but its still hapeneing
