I've been with them for 3-4 years in NYC/NJ. I've been nothing but happy, and in Jersey City, they've got better coverage than AT&T and Verizon (anecdotal, but repeatable, data). Their phone support has always been fantastic for me. Right before they switched to no-contract mode, I called in to cancel a USB data card I wasn't using much anymore. I have a phone (no contract, unlocked nexus 4) as well as that card, that had finished its contract some time ago. They gave me ~40% off of my entire bill if I agreed to a 2 yr contract. Then again, when I go out into some parts of the country, I get almost no signal. There was an HN post some time ago with a map of comparative cell-coverage.
