What devices are compatible with Google Fi?

Project Fi is compatible with a wide range of devices. Initially, it was limited to Google's own devices, such as Nexus and Pixel phones. However, with advancements, Project Fi has expanded compatibility to include various Android smartphones, both unlocked and those purchased through the Google Fi website. Additionally, iPhones can now be used with Fi. This broadens the options for users who wish to switch to Google Fi without having to change their current device. While compatibility is not guaranteed for every smartphone model, the selection has significantly increased. Users can check the Google Fi website to verify if their device is compatible or can consider purchasing one of the supported devices for a seamless experience on the Fi network.
