Why would an iPhone need a SIM card replacement twice in the last few months?

A family member's phone has needed to be brought into the AT&T store to replace the SIM card twice in the last few months. What can cause this?

We can share a few things that may cause for a SIM card replacement, @msxcski


A customer is usually required to replace their SIM due to the following reasons: 

  • SIM card was lost or misplaced. 
  • SIM card has been damaged. (Damage to the SIM card can occur when the device has been dropped.)
  • SIM card is blocked. (PUK or PIN blocked.)
  • SIM card error. (insert SIM or invalid SIM.)
  • SIM card age. (Some SIM cards were phased out due to our most recent network change and we now only support version 27 or higher.)

Wondering how to get a physical SIM card?

  • You can get SIM card kits at one of our stores, online, or from another online retailer. The kits come with three SIM card sizes.

If additional assistance is required with this matter, please have your family member contact us here on the Community Forums. Our Specialists are happy to help!
