Does anyone use this mobile service? It's very cheap. You are only charged for the minutes, data and text that you use. The average bill for a ting customer is $23 per month. So if you don't want to pay for a set # of minutes and data regardless how much you use, this is a good option. I just recently started using it and it's a very good deal. They use the same network as Spring and Verizon, so there's really no difference in quality. I definitely recommend checking them out at Ting.com. I think it's growing pretty rapidly, and for good reason.
Honestly, I pay less with tracfone. A 40 dollar airtime card will last me 3 months. They also have a bring your own device plan so if you want to use something besides their somewhat limited devices you can do so. I think I will choose to keep tracfone even if I upgrade my phone, because I don't think there is a better bargain anywhere.
