SOS Only on/off iPhone SE though connected to FIOS WiFi in same room as router

My phone goes on and off SOS Only through the day though  Apple iphone SE is connected consistently with Fios Wifi in the same room.  In settings, phone is setup to be able to receive and make calls via wifi.     On top left, if usually has "VZW WiFi, but that will change to Verizon or SOS Only throughout the day.    Cannot receive calls while SOS Only and sometime when "Verizon".   In all cases the bars showing access to router is fine and access via other means (including computer) continues as normal.  

Yes, rebooting normally fixes it for a time, but then it continues sometime later to SOS Only or whatever.  

Any fixes?
