My galaxy note 20 does not work after updating one ui . I have reset all the settings several times.  Still is not working. My sim card works on another phone. Please advise on this.  The sim card reader is reading but the only problem is network.  I have tried different network sim cards but still the same.

@Sirmothoa: To begin with, please head to Settings > Connections > Mobile networks > Access point names, and check to make sure that your network plan is registered here. If it isn't, tap the 3 dots in the top right > Reset to default, to see if this helps. Tap the Back button > Network operators > Select automatically, and make sure that this is toggled on. 

If the problem persists, power off your phone, remove the SIM card and give the gold contacts a rub with a dry, microfibre cloth, then re-insert it and power the device back on. When the phone has finished booting, check the top left corner of the lock screen, where your network details should be visible. 

To further troubleshoot the issue, please head to Settings > Connections > SIM manager, and make sure that your SIM is recognised, and toggled on. Also, you may wish to head to Settings > General management > Reset > Reset mobile network settings > Reset settings.
