Dont forget to let us know how it works on T-Mobile.
I received the P20 Pro today, and I am not disappointed. It works excellently here in Atlanta on T-Mobile LTE. I was a little worried because the phone is the international version, but I have not had any issues so far. It even connects to T-Mo's VoLTE, but there is no WiFi Calling. I also have the International Sony XZ2, and the difference in connectivity to T-Mo's network is night and day. I get at least to bars on the P20 Pro, and the XZ2 gets no signal at all in some areas. I will be selling the XZ2, and I plan on keeping the P20 Pro at least until the end of the year.
