Fix: ESIM Not Working On Galaxy S23

Samsung’s latest S23 series allows us to use both physical SIM cards and E-SIM cards. E-SIMs behave the same as physical ones, but you don’t have to manually insert one into the phone. Unfortunately, many reports say the E-SIM isn’t working correctly on the S23. It either says no phone number has been assigned or the SIM is not recognized.

There are system issues with the SIM manager. If you have any such with E-SIM on your S23, this article will help you solve the problem. These fixes apply to the entire S23 lineup, not just the base S23.

If none of the above methods worked, it’s probably an unfortunate hardware issue with your unit. Contact the service center, and find out which hardware issue it is. You might be charged a fee for a replacement if it’s not covered under warranty.
