Google has officially announced Project Fi, an MVNO that will offer consumers wireless service in the U.S. using cellular networks belonging to Sprint and T-Mobile. Additionally, Google will also use Wi-Fi networks when available. Google has developed a new type of technology that will connect subscribers to the fastest network possible at any given moment, regardless if it is a Wi-Fi connection or a cellular one.
The service will choose from more than 1 million Wi-Fi hotspots verified as being "fast and reliable" by Google. Once connected, the signals will be encrypted. Calls will be seamlessly handed over from Wi-Fi to cellular. Customers' Project Fi phone numbers are stored in the cloud, so they can be used on any device that supports Google Hangouts.
In order to subscribe to Project Fi, you will require a Motorola built Google Nexus 6, which is the only device which supports the network. The handset will use a special technology that will connect to either a T-Mobile or Sprint signal depending on which one is stronger at the time. The Nexus 6 will be offered to consumers in the "Midnight Blue" color with either 32GB of storage or 64GB of memory. Subscribers can opt to pay for the phone outright, which works out to $649 or $699, respectively. There is an option that will allow you to pay $27.04 monthly over 24 months for the 32GB model, or $29.12 a month over 24 months for the 64GB version. A credit check is required with this option. Those who already own a Nexus 6 can use it with Project Fi simply by inserting a special SIM card into the phone.
Google will charge $20 a month plus taxes and fees for unlimited domestic voice and texting, unlimited international texting, low-cost international calls, Wi-Fi tethering and coverage in more than 120 countries. Data will cost $10 per GB with overages billed at the same rate. At the end of each month, you are credited for any unused data.
If you are interested in trying out Project Fi, you can do so by requesting an invite from Google on the Project Fi website linked below. Keep in mind that in order to use the service, you will be required to own a Nexus 6 and pay a monthly fee of at least $30.
