Late last year, Google changed the name of its Fiji Project Fi to Google Fi, opened more Android devices, and launched a beta program for iPhone ($ 1,000 on Amazon) .
If you've signed up for or thought about iPhone with an iPhone, you should understand the following to set up an Apple product on Google's wireless service.
Compatible iPhone Models
According to a Google Fi support page, the following iPhone models work with Fi:
It's a good idea to check if your particular iPhone model is compatible with Fi, with the Compatibility Tool from Google.
What you need
In addition to an iPhone compatible with the Google Fi network, you will need:
You can order a free SIM card on Google Fi, either through the mobile app or through the Google Fi Store
After receiving your Fi-SIM card, turn off your iPhone, insert the SIM card, and turn on the phone. Then open the Google Fi app. The app prompts you to sign in with your Google Account and guides you through the setup process. It changes the APN settings on the iPhone to know which network to connect to, and can send and receive MMS messages.
The Fi app shows you what to enter, and gives you the option to copy the URL entered into the MMSC field. Press the button to copy the URL. If you enter it incorrectly, you will not be able to send or receive picture messages.
If the URL is copied, exit the Fi app and go to Settings > Cellular > Cellular Data Network . Those who are on iOS 11 must > Cellular > Cellular Data Options > Cellular Data Network and then
, Enter "h2g2" in the three different text boxes named APN – without quotation marks.
In the MMSC field, paste the URL that you copied from the Fi app. If you have not copied it, either go back to the app and do it now or copy and paste this "http://fi.g.co/mms/wapenc" again, without the quotes.  Go back to the Google Fi app and scroll through the last few screens until you're asked to restart the phone. After starting up, reopen the Google Fi app and complete the setup process. Your iPhone should now connect to Google Fi without any problem.
There are, of course, some reservations. Unfortunately, Google Fi iPhone users will miss some features that users of an official Fi phone can use.
Visual Voicemail currently does not work and also has the ability to switch between networks or use Wi-Fi calls and SMS. iPhone users can only use the hotspot feature in the US.
With the inability to switch between networks, iPhone users can use the T-Mobile network for their Fi experience.
