Mint uses the T-Mobile network but is one tier below T-mobile subscribers:

Lower QCI values are better.
> QCI 6 is applied to all of T-Mobile's postpaid and prepaid plans (except for Essentials) and Google Fi which also has QCI 6 as well. This means if you want the absolute best from T-Mobile, you want to get a plan directly from them. Even their cheap $10 prepaid 1GB Connect plan has priority data.
QCI 7 is applied to T-Mobile’s Essentials plan as well as all MVNOs (besides Google Fi) such as Mint, Metro By T-Mobile, US Mobile GSM LTE, and Tello.
I'm not trying to serve websites with my phone, I'm merely communicating.
And I have run out of energy for fighting an increasingly hostile service provider to bring my $130 bill (which used to be less than half that) back down to earth when it could be $15.
