I'm on Cellcom, a non-MVNO who owns towers in Wisconsin, USA. Data works but voice/txt don't. APN re-config had to be stolen from a working phone (APN config: name="Cellcom", APN="VZWINTERNET").
My understanding is VoLTE must be programmed into the modem & accepted by the carrier. I attempted a bit of simple modem AT commands to force a generic handshake to get voice/txt but no-go.
Ting (via T-Mobile) also worked for me (data+voice+sms) but their tower is 40miles away from home so ... I only got signal once in a blue moon on a cloudy night
