Project Fi is currently testing and rolling out VoLTE to improve call quality.
Voice over LTE allows Project Fi users to make voice calls over data networks instead of standard cellular networks. This will provide a cleaner connection for your voice conversations when LTE data is available. Google has said that it will also allow you to multitask because VoLTE doesn’t affect other activities that use cellular data like web browsing. The new type of voice calls will not count against your data allowance. They are currently testing this new feature with a small set of users and is only available if you see the “Enhanced 4G LTE Mode” option in the Cellular Settings section in the Data Usage section within your phones settings. Once the kinks are worked out with the test users, Google will roll out this feature to all Project Fi users.
Project Fi is the mobile virtual network operator (MVNO) that Google rolled out in April of 2015 and has been advancing the service ever since. They’ve found a way to innovate an industry that has been dominated by four providers – Verizon, AT&T, T-Mobile and Sprint. They done it by combining regular cell service from T-Mobile and Sprint along with access to Wi-Fi networks not previously available without a prior connection to. This has allowed Fi customers to use much less data because Wi-Fi networks are prioritized over cell networks saving a ton of money on data consumption. The simplistic billing process and streamlined mobile app makes tracking data usage and monthly charges almost a pleasure. I’m glad they’re continuing to innovate and add new enhancements to push Project Fi to the next level. However, they do need to start to support more phones besides the Nexus and Pixel phones if they want to truly compete with the likes of Verizon and AT&T.
