People calling but phone doesn't respond many times.

    I have a Galaxy S9 + and am having issues with people calling many times but the call never comes through.  I've had people call my phone and it rings on their end but nothing on my end.  Sometimes if they leave a voice-mail I don't get it for days.  I can make calls out with no issues and this happens lots of different places.  I'd understand if I had no wifi/cellular connection but I do.  My wife's phone, an LG phone from a couple of years ago has no issues at all with calls.  Anyone have any idea what could be the problem?  Oh, and it is with different callers, not just one or two.

     

    Thanks!
