Samsung A50 loses service after disconnecting from WiFi network.

Whenever I leave a location where I am connected to a wifi network, my phone will lose all cell service.  I get an "emergency calls only" notification and I cannot receive texts or calls.  The only solution I've been able to find is to toggle airplane mode on and off and then it will connect, but that's hardly any solution at all...it's a giant pain and one that I shouldn't have to deal with.  The phone and network should just "work."  Very frustrating...any help would be appreciated.
