Yeah stock, at first I was using the modded S4 MMS and sending and receiving didn't work over WiFi calling (not surprised!) So I went back and flashed the stock s4 app and sending and receiving worked over WiFi.. That's probably what it is in your case, modded MMS apps have never worked for me over WiFi calling, so you must be using plain stock app
