No SIM Card Installed – iPhone 4 [SOLVED]


What didn’t fix it:

What I noticed:



  • Replace the bad SIM card with the correct size.  I had some spare ones at work I was able to procure, however, you’ll likely need to stop by the Verizon/AT&T/Sprint store and have them give you one.
  • You should be able to simply take the old one out and pop the new one in (use a thumb tack or a pin to open the SIM tray on the side of your phone).  It only fits into the tray one way.  If it fits in the tray, you’re doing it right.
