Google Fi Wireless

Google Fi Wireless (pronounced /faɪ/), formerly Project Fi and Google Fi, is an American MVNO telecommunications service by Google that provides telephone calls, SMS, and mobile broadband using cellular networks and Wi-Fi. Google Fi uses the T-Mobile network. Google Fi is a service for US residents only, as of late 2023.

The service was launched for the Nexus 6, by invitation only, on April 22, 2015. The service was opened to the public on March 7, 2016. It began to work with additional device models, including the Pixel and Pixel XL smartphones, on October 4, 2016. On November 28, 2018, Google rebranded Project Fi as Google Fi and made it work with more device models, including partially with iPhones. In 2023, it was once again renamed Google Fi Wireless.
