Network issues after one ui 7 update

[aboutzahurul]

Following the One UI 7 update, 

the device displays full network signal strength; however, call functionality is not working. Incoming calls report the number as unreachable. A device restart provides a temporary solution. 

Additionally, network signal bars remain visible even with all SIM cards removed. Is this the expected behavior? Have other users experienced similar problems?
