How does Project Fi work?
Project Fi constantly checks 4G LTE and WiFi availability and selects which network to choose without negatively influencing battery life. If 4G is not available, the fastest available network type is selected. For launch, Google partnered up with Sprint and T-Mobile.
For the time being, Project Fi is only available on the Google Nexus 6. This is due to a special technology implemented in the device which is required to use Google’s SIM card with multiple network access. At the moment it is not clear which devices will be supported in the future, but I would expect this to be exclusive to the Google Nexus.
Project Fi integrates perfectly with Google Hangouts
Next to the (already awesome) covering of the cellular networks, Google also integrated Project Fi perfectly with Google Hangouts. Incoming and outgoing calls are available from all devices where you’re logged-in with your Project Fi account. This includes computers, iOS and obviously Android devices. You’re also able to send and receive text messages across all devices. In addition to that, voicemail and messages will be synched across all devices.
Project Fi cost structure
Project Fi starts at $20.00 USD plus taxes for unlimited domestic talk and text, unlimited international text, WiFi-tethering and cellular coverage across more than 120 countries. Mobile data comes in addition to that, for 10 USD per GB. Any data not used throughout the month will be charged-back to your credit card. There are no hidden fees and you’re able to cancel your subscription on a monthly basis. Additional information are available on the official website.
