I know the x3 supports Band 12, which is used by T-Mobile quite a bit in my area. In this area much of the coverage is band 12 only, so only LTE service is available. There is no fall-back to 2G or 3G for anything including voice calls.
However, T-Mobile doesn't seem to 'play nice' when it comes to unlocked devices on Band 12. I'm doubtful that VoLTE works on the X3 with T-Mobile, so therefore the device likely won't/shouldn't connect to Band 12.
Can anyone speak to their experiences and if it works or not?

Here is a link to the tech specs that show the bands that are compatible.
