Is this happening everywhere or in a particular place @b15H  ?

What's your signal bars like now you've updated ?

Look at > https://eu.community.samsung.com/t5/galaxy-s21-series/poor-phone-signal-on-ee-in-the-uk-try-this. 

You could try resetting your network connection in Settings, General Management,  Reset, Reset Network Settings. 

Sometimes this helps too > Clear your System File Cache via the instructions in the Samsung Link. You may need to hook upto a computer or insert your headphones to get to the recovery menu. https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/

Thanks so that rules out mast issues.

Please do follow the advice given. 

Also as a process of elimination try your sim card in another phone just to help rule out your network account and a faulty sim card @b15H

Hello I had the same problem after this update too, i switched flight mode on for 1 min and then turned it off and ive remained connected for now, its not as fast as it was before this update at connecting but its at least connecting again, hopefully samsung will sort this issue as it seems alot are having this issue - ive been a huge samsung fan but i am contemplating apple for the first time. just from the lack of response from samsung on this matter.
