Can't receive any calls nor messages

I looked up other forum topics that could give me the answer but none of them worked.

It’s always a good idea to list all the tips you already tried, so we know what not to suggest to you.
Also a little better description about how you fail to receive calls would be nice.
First thing I’d think of would be a permissions issue:

Check your phone app’s permissions and notification settings in Settings>Apps and Settings > Sound & Notifications. Also check if an antivirus app or similar may block your phone app from working properly.
