Pycom FiPy compatibility

Does anybody know if Pycom device FiPy with Expansion Board will work on the U.S. West Coast (4G LTE T-Mobile). I have seen a list of hardware/devices somewhere on a github that I cannot find anymore and this device was not in the list. But at the same time I don’t know if that list is really maintained and accurate. If FiPy is not working in my region what other device I can get that also have WiFi in addition to CAT-M1. Some decent development environment, preferably in MicroPython would be great too…
