Apparently some Project Fi customers have noticed improved voice call quality over the last few weeks. That’s because Google has been testing Voice over LTE for some users. It was announced four days ago over at the Project Fi Help Forum.
Hi everyone,
Some of you have noticed this already, but over the past few weeks we have been testing VoLTE with a subset of Project Fi users.
A few advantages of VoLTE are:
higher quality calls over data – without using any of your data allocation.
faster data browsing during an on-going call
faster call setupYou can tell you’re making a VoLTE call because your signal indicator will continue to display LTE instead of falling to H [HSPA] when you make or receive a call.
We will continue to keep you informed as we progress with our testing.
Thank you!

Unfortunately I’m not one of the lucky few yet who are getting to test this. If you happen to be a Project Fi customer you can tell if you are a tester by looking for the signal indicator to continue displaying LTE when you are on a call.
VoLTE lets you use your data to make a call, without using your data allocation. It also means that you’ll be able to use faster data browsing even while you are on a call, such as when you are looking up contact info online or need to look up directions.
You can also go into your settings – data usage – cellular networks and there will be a new switch for you to turn it on.
Currently Project Fi is limited to the Google Pixel and Pixel XL, Nexus 6p, Nexus 5x and Nexus 6. VoLTE support for Fi is limited to when you are on T-Mobile’s network since it’s the only US partner that fully supports VoLTE. No telling when Sprint or US Cellular will get on the bandwagon.
