How To Solve Project Fi 1 Ring Issues

There are times when Project Fi just doesn’t behave like it should.  It’s rare but it happens and when it does, figuring out how to sort yourself out can be a real time saver.  Recently I had an issue where I was receiving calls but it would ring once or twice then roll to voicemail.  I did some testing, restarted my Nexus 6 and cleared the app cache but nothing seemed to work.  The strange thing was, it started somewhat out of the blue.  One day I was fine, next I wasn’t.

I spoke with the Fi support team and I got this series of instructions to solve the issue.  And solve it, it did.  While the steps are a bit involved, it is worth having these instructions handy in case you ever run into this problem.  Obviously I can’t promise or guarantee that this will work 100% for you as it did for me – but it should.  As you will see after the break, the process is pretty involved and invasive. Also be aware that this involves clearing your device’s cache.

To go through this process, you will need to have your Nexus device running on Project Fi and will need to have a paperclip or SIM pin tool to extract the SIM from your device.  The step-by-step instructions on how to solve the 1 ring problem can be found after the break.

Project Fi 1-2 Ring Then To Voicemail Step-By-Step Resolution

  1. Power off your Nexus device
  2. Using the paperclip or SIM pin, remove the Project Fi sim from your phone then reinstall the empty SIM tray.  Leave your SIM out of your phone for now.

  3. Start your Nexus phone without the SIM installed.  You will get a “No SIM” warning but just OK your way through it.
  4. Go to Settings>Apps>Project Fi>Storage and in the app settings, tap the Clear Cache button.
  5. Tap your Home button then go to your Apps and uninstall the Project Fi app from your phone.
  6. Go to Settings>Storage & USB (under Marshmallow – Just Storage in Lollipop) and scroll down to Cached Data.  Tap it and tap OK to clear your device’s cache.
  7. Power off your Nexus phone again
  8. Using the paperclip or SIM pin, remove the SIM tray from phone, reinstall the Project Fi SIM and insert it back into your phone.
  9. Power up your phone
  10. Go to the Google Play Store and reinstall the Project Fi app

As you can see, this is a pretty significant amount of work to solve the problem but in my case on my Nexus 6, it solved the problem on the first try.  In all, it takes about 5-10 minutes to do all of this so you won’t be out a significant amount of time.  This is also one of those How To’s that hopefully you never have to use but keep it bookmarked just in case.
