Project Fi on Ubuntu Touch

Project Fi SIMs appear to work great in Ubuntu touch, but there's a little bit of configuration you need to take if you want your data connection to work properly. Both the standard Fi SIM and the new Data-Only SIMs work in Ubuntu Touch. Note that only the T-Mobile side of Fi will work, since there is no switching support. Here in Denver, this is not a problem at all, but your mileage may vary.

(All of my testing was performed on a Nexus 5 in 15.04 r15/rc-proposed, which was installed from the ubports.com server.)

You'll need to activate your SIM first. For a regular SIM, this means inserting it into a supported Android phone (Nexus 6, 5X, or 6P) and completing the activation there. For a Data-Only SIM, simply go to the website and enter in your SIM's code (this is fairly standard).

Next, you can insert the SIM (And adapter, if needed) into your Ubuntu Phone.

Boot the phone up and go into System Settings > Cellular > Carrier > APN, then tap the + icon to add a new APN. Set Used for: to "LTE", name it "Project Fi - LTE", then set the APN to "h2g2". Then hit the checkmark icon to save it, and check the newly added APN to activate it.

If you need calling/SMS (For a primary SIM card), then hit + again, set Used for: to "Internet and MMS", name to "Project Fi - Cellular", and the APN to h2g2, then the MMSC to "httpmmsc1.g-mms.com/mms/wapenc", then save it and activate it as well.

You might want to reboot just to make sure everything is applied correctly, but it shouldn't be necessary. Note that it may take a few minutes to get a data connection after the reboot, but it should eventually come.
