Project Fi, which previously only worked on a narrow selection of Android phones, has been rebranded to "Google Fi." The service now works on a wide range of phones from Apple, HTC, Samsung, Motorola, LG and others. However, Google still recommends that customers use phones that are "designed for FI," as other phones won't necessarily support Fi's network switching or other specific features. Fi for iOS is in beta, so not all Fi features will be supported on this Phone. Setup also requires a little extra attention, but we'll walk you through it. Before switching, make sure this phone is unlocked.
