Ting will buy you a cup of coffee just for stopping by and seeing if your AT&T device can work with its service

The a-la carte shopping of features, like low minutes, a bunch of text messages, and a couple gigs of data can be less than $50 per month. If things are running really lean, you could drive the bill down to under $10. You can also go data only, 2GB for $35.
Ting believes that if people realize they can move their device off AT&T, they will. “If you can bring your phone to Ting, the calculation gets very simple. You are going to have a better customer experience and you are likely going to spend less,” according to Ting VP of Sales and Marketing, Michael Goldstein, “But sometimes people need a more immediate incentive to take that first step. Until a better incentive comes along, we’re going to stick with coffee.”
