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 phone. I first wanted to convert my SIM card to eSIM. But I realized that once I convert that SIM card to eSIM, I will no longer transfer it to the other phone. I then realized that having 2 SIM cards (SIM and eSIM) sounded quite hard to get used to. So I decided to switch the SIM card back to regular SIM by removing the eSIM off of my SIM card. But once I've done that, I have not been able to reverse its service availability unless I contact you which I'm not able to either. And that's when a number of sad results happen to my SIM card: I will only get emergency calls, I will get an error saying "Not registered on network" after making one phone call or text, and I will no longer have available mobile network service on it after I made changes. I restarted my phone, I reset my network settings, I checked my SIM card, I checked my phone's settings, I checked the network, and I checked basically everything; I still have never been able to fix and reverse my SIM card and its settings back to the way it was before. I'm in desperate need of help: how am I able to get it all back again? Thanks in advance for your answers.
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.
