Yep, I quit T-Mobile and switched to Mint last month for this exact reason. My price is now 1/4 what I was paying before, and everything else is exactly the same. Should’ve done this years ago.
But then Verizon would get some of that money. The pile of shit company that programmed a physical key on your phone next to the scroll wheel to bill you 1.99 a month for the privilege of using 0.00001 MB of data if you accidentally clicked it during the month and it opened their shit “get it now” store. Literally the company that pushed for hostile design back in the 2000s. Fuck them. Fuck Bank of America , Wells Fargo and Comcast.
They’re also assholes as customers. Worked for a company that did monitoring for them and they were an absolute nightmare to deal with. They were so demanding of our time and liked to wave around legal threats so often that eventually management shelled out for a consulting company (who were SMEs with our product) just to manage their install.
