7 Best Fixes for ‘No SIM Card Installed’ Error on iPhone

To enjoy dual SIM functionality on your iPhone, you can use a physical SIM and set up an e-SIM. While Apple hints toward the complete SIM tray removal to make portless iPhones, many users still rely on a single physical SIM card for using the mobile network.

But some users complain of seeing the ‘No SIM Card Installed’ error on their iPhones. If you are also facing the same, here are some solutions to help you fix this problem and stay connected with your contacts.

1. Re-Insert SIM Card

Starting with the basic solutions, you can pop out and re-insert the SIM card. Ensure that the placement of the SIM card is correct in the SIM tray. Eject the SIM tray and re-insert it with the SIM card to check whether your iPhone is reading it. If this solution doesn’t work, keep reading the next ones below.

2. Check For SIM Card Damage

The second solution is checking whether there are any scratches on your SIM card. That’ll happen if you remove and insert the SIM card again in the iPhone multiple times. This can limit the SIM card from being read by your iPhone. In case you see a lot of scratches, we suggest contacting your Mobile Network Operator for a new SIM card.
