Google Fi was launched to prove that a network-of-networks serves smartphone users better than a single mobile carrier's network. Patents related to Google Fi, filed in early 2007, explain Google's vision – smartphones negotiate for and connect to the fastest network available. The patent and Google Fi share a common notion that the smartphone should connect to the fastest network available, not a single carrier's network that may not provide the best performance. It breaks the exclusive relationship between a smartphone and a single carrier. Meanwhile, a story at BostInno points out that Google's not the only one with a network-hopping hybrid approach to phone calls.
