Samsung galaxy a32 no network available issue

[Sobiiii]

Since a week I'm facing this issue sometimes phone shows signals but whenever I try to call it appears "no network available " 

I visited many repair shops but no one identified its real cause. 

I'm just confused what to do in this situation.

Try to restart your phone after recent update its happening even in my s23 ultra

Ok thanks will check. But I did that before many times for a time being it works then again same issue.
