I don't think you actually save any money on Ting. Their biggest data plan is 3000M for $55 (with no text messages and no phone service), compared with T-mobile's unlimited everything for $70. The innovation they offer is that if you don't use anything and know you never will, you only pay $6 a month. But then again, I could get you the complete lack of calling, data, and text for $0 a month. You don't even have to buy a phone.
