Are you getting a SIM error on your iPhone 13? The SIM card is necessary to use the cellular plan on your phone, though many phones now have eSIMs (embedded SIMs) that you can use instead of a physical SIM card. You may be getting a SIM failure error because there's something wrong with your SIM card or cellular plan. In this article, we'll go over the top methods to fix the "SIM failure" error on your iPhone 13.

Get a new SIM card from your carrier.
If your current SIM card isn't working or is damaged, you can replace it with a new one from your carrier. You should contact your carrier to see what options are available for SIM card replacement.

Contact your carrier for any eSIM-related problems.
If your phone doesn't have a physical SIM and you're experiencing issues with your eSIM, you should contact your carrier for help. If needed, your carrier can issue a new eSIM to see if that will fix the issue.
While your cell carrier typically takes care of SIM-related issues, Apple Support can assist if nothing else is working. You can
