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

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.
