Google’s Project Fi service was established in April 2015 providing cellular phone plans for $20 a month which includes: unlimited domestic talk, unlimited domestic and international text, and ability to use your phone as a Wi-Fi hotspot.
Data is an additional charge of $10 per gigabyte and you will only be charged for what you use. If you have a 2GB data plan per month and only use 1.2GB, your account will be credited $8 for the unused data.
The catch, at least for the time being, you must have a Google Nexus phone to use the service. Project Fi is known as a MVNO (Mobile Virtual Network Operator) that will switch your connection to the strongest possible signal in your area that the service has access too.
Project Fi uses free public Wi-Fi connections and the networks of Sprint and T-Mobile to provide coverage in over 120 countries. Google has stated your data will be secure.
Project Fi subscribers can also get a data SIM card for their tablets at no additional charge to share their data plan. This can bring internet access to your iPad Air 2, Galaxy Tab S and more. For now, access to this service is by invite only.
