An anonymous reader writes: Google unveiled today a new cell phone service called Project Fi. It offers the same basic functionality as traditional wireless carriers, such as voice, text and Internet access, but at a lower price than most common plans. From the article: "Google hopes to stand out by changing the way it charges customers. Typically, smartphone owners pay wireless carriers like AT&T and Verizon a bulk rate for a certain amount of data. Google says it will let customers pay for only what data they use on their phones, from doing things like making calls, listening to music and using apps, potentially saving them significant amounts of money. For now, the program is invite-only and will only be available on Google's Nexus 6 smartphone."
