How to Fix No SIM Card Installed Error on iPhone 6s

If you are getting no SIM card installed error on iPhone 6s, make sure that your plan is active by contacting your network provider. You can also perform a hard reset on your phone or update its software version. Performing a factory reset might also help. For more details, read further.


If you get a pop-up on your iPhone 6s telling you No SIM card is installed, or you see No SIM in the top left corner instead of your signal, this can be caused by either a software or hardware issue. Here are some steps you can take to try to solve this problem:

    • Is this an iPhone you recently purchased? If yes, make sure it was not blacklisted or that it was successfully unlocked if it didn’t originally belong to your Carrier.
    • If your iPhone was not recently purchased or this is a recent issue, try a SIM pull.
      • Power off your iPhone.
      • Remove your SIM card from the iPhone.
      • With a dry cloth wipe the SIM card clean and blow into the SIM slot to clear any dust.
      • Re-insert the SIM card and power on your iPhone and test.
      • If issue persists proceed to the next step.
    • Go to Settings > General > Reset and select Reset Network Settings.
      Note: This will erase any saved WiFi connections, you must reconnect to WiFi after this step.
      • Your iPhone will show the Apple logo and restart.
      • Once your iPhone is back on, see if it’s still giving you the No SIM error message.
    • Verify if your iPhone is up to date.
      • Go to Settings > General > Software Update.
      • If there is an update available then make sure to download it.
  • If none of the above worked, try a factory reset. To do that, follow these steps:
    • Access Settings from the Home screen. 
    • Tap General.
    • Scroll down to and then select Reset
    • Tap the Erase all contents and settings option.
    • Enter your device passcode once prompted.
    • Then tap to confirm all settings reset.

If all else fails and you are still getting a no SIM card installed error on iPhone 6s, then it is likely caused by a hardware issue in this case. Consider having your iPhone replaced or repaired through Apple.
