7. Reset the Network Settings 

The no SIM card error might also occur if the network settings of your phone are corrupted.

  4. Upon restart, set up the network on your phone, and afterwards, check if it is clear of the no SIM card error.

8. Clean the SIM Card

If there is corrosion on the SIM card, it may fail to properly connect to the phone’s SIM card holder and thus cause the issue. Cleaning the SIM card and reinserting the SIM into the phone may solve the issue.

Also, if your phone has been in tight spots for longer times (like in your pocket), then the constant pressure on it may cause a slight bend in the SIM area of the phone and create a distance between SIM and SIM card holder, hence causing the no SIM card error. In such a case, placing a piece of paper under the SIM and reinserting it may solve the problem.

  1. Power off your phone and remove the SIM card from it.
    Use a pin to remove the SIM card
  2. Now clean the SIM (the contact side) with pink eraser rubber.
  3. Then use a lint-free cloth to remove any remnants of the rubber from the SIM and then use a compressed air can to blow air in the phone’s SIM card holder to remove any debris from it. Afterwards, reinsert the SIM into the phone.

11. Reset Your Phone to the Factory Defaults

Before proceeding, back up your phone’s essential data and fully charge it. Also, it will be better to check if a new SIM card of the same number resolves the issue before resetting the phone to the factory defaults or you can opt for an E-SIM (if supported).

  1. Launch your Settings and select System.
  2. Now open Reset options found at the bottom of the screen.
