Wifi Calling Availability
Device: Yes
Carrier (T-Mobile): Yes
Current OS Version (24.04-1.2): No

Note: My assumption that 4G LTE and wifi calling were synonymous is that the two technologies always seemed to be in the same discussions. I thought wifi calling was dependent on 4G LTE. However, this is not the case. Thanks to those who had taken the time to reply and help make me aware of this.
