I consistently have to re boot my phone because when I make a call they can't hear me and I can't hear them. I have to reboot my s21 ultra to have it work again. Frustrating!!!!!!

Any advice would be most welcome

Is this happening in a particular area or everywhere @Members_M8iyvAg  ?

If in a particular area then check with any available network mast checker your mobile network provides to see if any cell masts are showing a known fault.

Contact your networks customer services to ask.

As a process of elimination try your sim card in another phone and another sim card in your phone.

This will help to rule out the sim card or phone at issue.

You can reset network settings in your phone via Settings.  General Management,  Reset and then Reset Network Settings.

The advice I offer is my own and does not represent Samsung’s position.
I have no affiliation with Samsung.

I had the same problem; turned out I pressed "volume up" and "power" key simultaneously at one point or another, which mutes all sound or something. Pressing it again toggles off
