Mint mobile in NOVA/DMV

Does anyone here use or has used mint mobile as their mobile carrier?

What’s their coverage in the area like? Any issues with connectivity, speed…?

I know they use T-Mobile’s infrastructure for their network and I’ve never used T-Mobile so I can’t speak to that.

I do like their prices compared to my current carrier, but I don’t want to switch if that means worse service.

Any thoughts?
