Pixel 4a (5G) is currently the only Google-made handset available through T-Mobile, but this could change soon.
Google and T-Mobile yesterday announced a partnership that encompasses a broad range of services, including making Messages by Google the default messaging app for T-Mobile’s Android phones, promoting Google One as the preferred backup solution, and winding down the TVision live-TV service to steer customers towards YouTube TV.
T-Mobile boasts the most Android handsets in the US and the roster is likely to include more Pixel smartphones in the future, as droidlife has pointed out.
