No SIM card error

A few people have run into a glitch where the iPhone 6 keeps complaining about the SIM card. It might say “Invalid SIM” or “No SIM card installed”. There are a few things worth trying.
Potential solutions:
  • Try toggling Airplane mode on and off again.
  • Restart your iPhone by turning it off and on again.
  • If you recently inserted the SIM card and started getting the error then there’s a chance it’s damaged or dirty. Try popping it out and taking a look. You can use a pencil eraser to clean the gold contacts and then blow away the debris before putting it back in your iPhone.
  • Make sure that your software is fully up to date via Settings > General > About.
  • Try the SIM card in another device if you have a compatible device, or try a different SIM card in your iPhone 6.
  • If the problem persists then contact your carrier or Apple.

If pressing the home button on your iPhone doesn’t always get a response, then the device may have a problem, even if the issue is intermittent.
Solution:
  • Apple is apparently aware of a manufacturing issue with the Home button on some iPhone models. Make an appointment with the Genius Bar at your local Apple Store to discuss the issue.
