Galaxy S21 not registered on the network error after a new update or flashing new firmware?
Suppose the error message started appearing after you flashed a new firmware. Chances are you have flashed an incompatible firmware. For example, if your phone is carrier-locked to T-Mobile and you have flashed O2 firmware on it. You will not have registered due to a network error. In order to solve it, you will have to install the appropriate stock firmware on your Galaxy S21. You can use this guide to flash the firmware.
Sometimes, after an OTA update, if you encounter this error, chances are it will be solved after a reset if none of the solutions mentioned above work for you. Factory reset your phone. Or just reset the settings of your phone while keeping the data. You can back up your phone on your PC via Smart Switch before performing a factory reset.
