VoLTE in Japan?
GSM-phones built for the US (and GSM) aren't compatible with 2G in Japan which is based on CDMA.So I'd like to know can I use VoLTE in Japan when roaming using Tmobile's roaming agreements with the carriers in Japan? And if so, does that work fortxt messaging as well? If VoLTE is a no go should I be prepared to use VoIP alternatives (I.e. with a different phone number)? Thanks! David
