In my case, my cellphone carrier is a small mvno and they use at&t network. Fast charging is good. For that price, this can't be beat. But battery is not too amazing.

The phone works flawlessly on the mint mobile network, and i'm sure it'll also work on the t-mobile network. Only 1-2 official custom roms exist for 11lite. Use cellmapper. App to get the best mobile experience.
