If this doesn't fix anything, you can remove the iPhone's SIM card tray with a paper clip or ejector tool and reinsert it. In these cases, you can attempt to push the tray in all the way. If your SIM tray has not been inserted completely, your iPhone won't be able to read the SIM card properly and it will give you a no SIM card installed error.Īlso, if your SIM tray is broken, it may prevent the iPhone SIM card from sitting properly, even if it can enter the phone. Every iPhone model has one, even down to the very first model. The SIM tray is the receptacle for your SIM card. This will help expel any dust that might be present to enable it to work properly. If you have compressed air around, you can blow it into the open SIM slot.

If this was the problem, then you should see your SIM card installed successfully after reinserting the SIM tray. To fix this problem, all you have to do is take your SIM card out and clean the gold chip with a soft cloth ( microfiber is best if you have one) and put it back in. This can be the case if you're using an old phone. It may also be as a result of dirt or dust accumulating in your SIM slot. If that chip gets dirty (typically with oil from your fingers), it can affect the way your iPhone reads the data and communicates with it. That little metal chip that takes up most of the backside of your SIM card is the part that's responsible for its functionality.
