google-project-fiLooks like Project Fi is looking to get a bit more versatile in the near future.  Currently, the service offers voice calls via 3G via Sprint, T-Mobile, & US Cellular.  Google is currently testing LTE voice calls over Project Fi.  

Looks like T-Mobile will be the partner providing the VoLTE service since their the ones better suited out of the 3.  Sprint only has HD Calling w/ its own VoLTE is still in the works.  They’re testing the new service w/ a small group of users before kicking off a full rollout to all of its Fi subscribers.  More than likely sometime later this year.  

Any Fi users looking to get in on this action?
