Anyone else's IPhone x having trouble reading there sim card? My sim card never had issues in my SE 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!

I recommend you go to your wireless carrier’s store and get a replacement SIM card for it.
