reduce your cell phone bill minutes by using uma wifi calling

TMobile has introduced new cell phones that can use your home's wireless internet connection to make and receive calls. The technology is called UMA, or unlicensed mobile access.

It does cost an extra $10 a month, but you might be surprised to know that they don't count those minutes against your plan. So, depending on how often you use your phone at home, you can move to a lower cost plan and save way more than the $10 charge.
