Dear brother, this problem I faced also in my A51 and M21 after previous month update and fixed that easily by reset settings
follow these steps...

"Goto settings > general management > reset > reset all settings "
after reset it will restart automatically. And your settings will be default and new 👌
It's very safe and no any type of data loosing... 👍

Put the sim card in other devices and check if there is a problem with it, if not restart the phone again -> insert sim card -> and reset the access point name.
