Minternet? T-mobile 5G home equivalent?

I’ve been a prepaid Mint customer for 7 years. Mint just came out with a 5G home internet plan cheaper than T-Mobile, especially as a phone customer, as low as $30/mo. Using the same Gateway modem/router and towers as T-Mobile. Can anyone share info if they are on T or M home? Former comments go back to 2022. Thanks
