Google recently announced their intention to become a cellular services provider and compete with ATT, Verizon, Sprint, and T-Mobile. What they are doing is launching an MVNO (Mobile Virtual Network Operator), which means they will be offering services on another carrier’s network. In this case, they will be providing phones that will work on two networks, Sprint and T-Mobile’s. In this way they can provide better coverage than either network would provide individually.
There is a long article on TechDirt that covers this project in much more detail, but my thought is this: if your cell phone plan is up for renewal, and you are thinking about switching carriers, you might want to wait until this plan shakes out. I foresee the opportunity to save a bunch of money by switching to Google, and who knows, this may be a major incentive for your current carrier to offer you a better phone and data plan than you have now.
