With all the geeks, I was really expecting more Ting love. My cell phone bill is now less than $30 a month with an android smartphone, and I'm getting the same service with better support than I was before.
Essentially, Ting's a cell phone company run by geeks (tucows), for geeks -- think web startup for the cell industry. They bill for what you use, with no contract. They use the Sprint network, and use Sprint phones (except for the iphone which is "coming soon"). Their support is fantastic, very quick responses and good service (I've submitted two tickets for minor issues, all resolved in less than 5 minutes via email).
The great part: if you have a smartphone that can connect to WiFi and you're around WiFi for most of the day, you can use Google Voice and an VoIP app to bypass cell charges and only use the WiFi for all your talk/text/data. And when you're away from WiFi, you can use your cell data to do the same.
For me, I'm around WiFi at least 90% of the day. So I just have my smartphone connect to that. The only charge I get from ting is a small amount for data usage when I'm out and about. Because of how their plans work, that means my bill has been between $15-30 a month since I signed up.
The downside is that, while the plans are much cheaper, the phones are unsubsidized. This usually isn't too big of a deal; in my five months on Ting I saved enough to buy a lastest-generation upgrade on ebay. I just wish I had known about them before.
