Not registered on network after converting and deleting an eSIM on my SIM card
I've decided to exchange two SIM cards between two of my phones: Samsung Galaxy A32 (old) and Galaxy S21 Ultra 5G (new). I've been experimenting with new SIM manager settings on my new S21 Ultra 5G p...
When you convert your pSIM to an eSIM, the pSIM is deactivated and no longer usable. You will need to purchase a new SIM card and have it activated with your number. The quickest way to do that is, to visit your local T-Mobile Store.
What if you reset your SIM card or your phone to factory and back up your SIM data to the cloud? Will it still help?
Where the eSIM is stored is not backed up. It would exist on a part of the device that even if factory reset. Would still be there. When you delete it, you have erased it. You used to be able to redownload your eSIM from your my.t-mobile.com account but that was changed after a lot of SIM swapping scams hit. You can still purchase another eSIM online to activate on your device and have your number assigned to it.
