Switching Physical Sim to ESIM - S21 Unlocked

I have an S21 Unlocked phone (obviously with an AT&T sim) recently updated to Android 12.


1. How to switch from AT&T Physical Sim to Esim?

2. Once Esim is activated, Physical sim is deactivated. Can you switch back to Physical sim again and how?

3. For questions 1 & 2 can you do it without going to the store using an app or anything to do this?

We notice that you're interested in migrating to a eSIM, .


You can migrate from a physical SIM to an eSIM which must be done at your nearest AT&T store. To revert back to a physical SIM, you must purchase a new SIM. You'll also, do this in stores. We hope this information helps. Let us know if you have additional questions. Thank you for reaching out to AT&T Community Forums!
