However they are counting on the misleading practice that most people are busy and won't ask questions.
Lot's of nonsense gets pushed like this.

Even before the acquisition, Mint Mobile was just a T-Mobile MVNO. While Mint Mobile has less expensive plans than T-Mobile, and switching would reduce T-Mobile's profit margin, the quality of Mint Mobile's service is also lower:
> Mint runs on T-Mobile networks so will get the same coverage except it does not get domestic roaming (on AT&T, Verizon, US Cellular, and other small regional carriers such as ACS/GCI in Alaska) that T-Mobile post-paid or pre-paid does. Mint is “deprioritized” (on QCI 7) meaning it will get slower speeds than most T-Mobile plans (that are on QCI 6). How much slower depends on the exact second how many people are on the same tower & band compared to the capacity of the tower/band, but with speeds usually between 20-90% of T-Mobile Magenta/Pre-Paid customers at the same time & location.

The U.S. wireless carrier industry is in desperate need of more competition. Price increases (such as this one and T-Mobile's earlier removal of the autopay discount for credit card purchases) are exactly what happen when corporate consolidation (T-Mobile merging with Sprint) reduces the number of high-end carriers from 4 to 3.
