I am surprised that I don't see any comments on Ting wireless. If you have multiples phones in a family or business that you want to pool together it can save you tons of money.
Instead of paying a flat rate for "unlimited" everything, you pay only for what you use -- a great option for folks who may consume a lot of one thing but very little of another.
Ting charges $6 per device on your account, with no limits. Then everyone pools their voice, text, data activity into that same bucket system. You can check with their usage calculator if and how much you would save:

They use the T-Mobile network for GSM devices and Sprint for CDMA. If those networks have poor coverage in your area than forget about it. I never had a a problem with GSM.
Since Dan has no referral link AFAIK kindly use mine:
