5 Check SIM Card

Check SIM Card if the above things don't work for you. SIM card is essential to make or receive any call, hence if there is any damage or scratches on your SIM Card that could hinder in establishing a connection. Eject the SIM card tray with the SIM-eject tool and check the SIM card with other smartphones to see if it works fine. Try inserting any other SIM card into your iPhone and check if you still can't make or receive calls on your iPhone or not.

6 Check with Your Carrier

After reinserting the SIM card, if it still doesn't resolves, call your carrier. Before calling, make sure all your bills have been paid off, just to ensure that it isn't an unpaid bill block. If you have paid all your bills, call your carrier and ask them if any issue is persisting on the network to know whether it's just you or others are facing the same issue. Or else, ask them for a SIM card replacement if you found your SIM card damaged.
