What is the cheapest way to keep my phone number?

I have way too many phone bills. I have a land line, a business landline (I work from home) two cell phones and it's nonsense! Is there any ways to save on phone bills? I dont want to lose my numbers

You could get T-Mobiles HotSpot @ Home, which lets you have unlimited calling at home. You could cut out one of the cell phones too. So, you could have a cell phone as your home phone and a cell phone, and your business land line. To keep the cell number, wait til one of the contracts expires then take it to t-mobile.
