In a post on Project Fi Help Forum, Google confirmed that Project Fi is now trying voice call by using LTE technology for a limited group of subscribers. The feature has been available to significant carriers such as Verizon, AT&T, and T-Mobile for quite a while and finally making its way towards Google's system.

According to Digital Trends users can only figure out if Voice over LTE has been activated is by looking at the wireless signal indicator during a call. If it keeps on showing LTE, instead of falling back to HSPA, that person will be a lucky individual from the group that has got the feature.

The test had been occurring for a few weeks, however, it is just now that Google has released a public proclamation confirming about the said feature. Voice over LTE have various advantages that include enhanced call clarity, faster web browsing during a call, and faster call set up.

In addition, TP reported that Project Fi is a mobile virtual system that has been formed on account of Google's cooperation with the system partners like T-Mobile, Sprint, and U.S. Cellular. Since Google's administration does not rely on a single carrier, it can change network operators to give clients an ideal experience that might lead to better connections.

Voice over LTE is the most recent feature to Google's system, which has seen a plenty of useful updates over that last several months. The service is, however, a quite premium and it is limited to only a couple of Google Android cell phones like the Pixel, Nexus 6P, and Nexus 5X.

Unlike the other carrier, Project Fi refunds clients at the end of the month for the unused data. With that, coupled with additional features like automatic switching Wi-Fi hotspots and global high-speed data in several countries with no additional charge, has made Project Fi more popular by choice.
