so according to one plus the phone will work on everything except for 5G. It is not going to be in millimeter wave phone at least on Verizon Verizon has its own special 1 + 8. the best place for the OnePlus 8 pro is actually T-Mobile because it has all the bands to work on low band 5G in mid band 5G. I don't see any millimeter-wave phones or phones that will come out with all 35 g bands until millimeter-wave is more widespread that's going to be like 2 or 3 years however T-Mobile is going to have widespread mid-band spectrum pretty quickly probably by the end of 2020 you'll have about half the country already or half their Network already melted into one.
