Google Pixel 6?

Yeah I personally took that as a... It's coming but I can't say but who knows... That being said... I looked back at the rest of the thread ... Generallyt speaking (and I mean always with extremely few exceptions...) If a company makes a phone as an unlocked direct from manufacturer device... I.e. apple and their iPhones, Samsung and the Galaxy lineup.  They will work without issue and have all the bands built in for all carriers.  This has been the case for a long time.  Example is apple sells various devices for various carriers but they are all the same phone.  The only difference is that the ones for carriers are locked to that carrier for the purposes of carrier financing.  But once the phone has been unlocked (i.e. you pay cash for phone or you payoff the lein) the phone is functionally  the same to any carrier's network.  The exception to this is when you see a device say... The LG V60 ThinQ which was made exclusively and marketed as such for att and I think maybe a Verizon model?  Those were unlockable and able to be brought to tmobile but lacked certain bans (also some bands were introduced after the phone was made).  So in the event Tmo doesn't do the pixel at launch if Google sells an unlocked one (you can check the bands they will publish upon release) it 99.99% will be good as if Tmo sold it direct.  (Promise I'm not making this up used to work in telecom on network and device side)
