Wifi Calling SMS/MMS support?
I have 4.1.2 on a T989 using a TW interface only because my home has no coverage and I use WiFi Calling as my sole means for voice, sms, mms. Would this still function? Specifically the MMS portion, as no 3rd party app yet recognizes that my WiFi is used for MMS and it tries to fire up my 3G/4G connection (which doesn't exist).
I am asking because I can't get it to work, or maybe I've not set up a particular setting correctly yet. APN changes needed to get it to work maybe?
