Google decided to give up the goods, and let them all in. More phones can now use Google fi (Project Fi), and this is a GREAT thing. Opening the doors to everyone is a major win, and they can take LOTS of users from others carriers.
The coverage on Google Fi is amazing, and I have nothing but good things to say about it at this point. Been using project fi since it launched, and I’m staying with it. Love it. Video on how to setup your iPhone for project fi below.
