Why Does My iPhone Give Me a NO SIM Warning?

Episode 1721 (1:15:00)

Jane from Torrance, CA
iPhone 8

Jane says her iPhone 8 gives her a NO SIM warning every few days and she has to take out the SIM and put it back in. But then it'll do it a few days later. Leo says that chances are the SIM is warped and doesn't sit flat in the slot. But the good news is she can request a new SIM from the carrier. Just ask them.
