Anyone use Mint Mobile? How good is it?

[Indus]

Is it reliable like no dropped calls or calls going straight to voicemail?

And more specifically how is it for T-mobile (unlocked) phones? I know it uses the T-mobile network but how does it work?

I heard an ad for it recently so looked it up. It is pretty expensive. I got my MIL a plan at Tello and it is $14 a month. Sure they use Sprint (what I have) but it works fine in this area (unless you are on a mountain). I am sure Mint works 100% the same as T mobile if that is what network they lease.
