Not outgoing or incoming calls after December security patch

[Members_K4vt1W6]

Hi, 

I updated my S21 FE with December security patch, but after that there is no outgoing or incoming calls. I tried everything; reset mobile network, cleared cache partition. Can anyone please help me what I have to do?

Thanks.

Phone samsung help number, you will get it online, ask for remote session, that's the easiest and fastest way to solve most problems.
