scottnezos, Mar 3, 2019 : Don't waste your time with the T-Mobile version. I have it, upgrade to the international version of the software, and added the dual SIM tray. if I were to do it over again, I would buy direct, and avoid the conversion process. These are great phones that do not need the carrier B.S. if I were OnePlus, I would just crank up the marketing in the US, and avoid letting carries mess with their phones like Apple. OnePlus should control their updates and user experience.
