The Moto X Style supports T-Mobile's 700Mhz Band 12 which is great. However will it support T-Mobile VoLTE and VoWiFi abilities? Also, T-Mobile just announced this week the network will support Rich Communication Services (GSM Association) that Europe has adopted that will really amp up SMS/MMS texts into the chat and video LTE age. Missing RCS isn't a deal beaker for me but missing T-Mobile VoLTE and VoWiFi would kill it for me.
