Can I use an Ulefone on my TMobile account?
Want to buy a Ulefone and use it on my existing line. Is this possible?
The specific model of the device always helps. Looking at a few of their devices though. T-Mobile band compatability is very limited. Knowing what bands are deployed where you intend on using it would also help. Even if a device lists VoLTE and HD Voice compatibility. That doesn't mean it will work with T-Mobile's implementation. T-Mobile uses Google's stock implementation of VoLTE and WiFi Calling.
