Same Network, Different Carrier: these are separate, "alternative" companies that use the same wireless networks as the major carriers, usually at a lower price. It's your way to use, say, Verizon Wireless, without paying Verizon's prices. You can choose your favorite prepaid carrier and see what network they use, or you can choose the network, like AT&T, and see what carriers operate on that network, for less. You get your phone, plan and customer service from these alternative companies instead of the underlying carrier. Some use more than one network and some allow you to choose your network. What providers made this list?
