It's finally official, Google has launched their very own cell phone service and are calling it Project Fi. Project Fi is only available for Nexus 6 owners in the United States but I think it would be safe to assume more people will be eligible in the future. Right now you have to apply to be part of the early access program, but chances are good that Google will be opening this program up to more users in the near future.
Here is the deal:
Our plan starts with the Fi Basics for $20 per month. This includes:
Unlimited domestic talk and text
Unlimited international texts
Low-cost international calls
Coverage in 120+ countries
Then it's $10 per GB for data. $10 for 1GB, $20 for 2GB, $30 for 3GB and so on. That's it. With no annual contract required.
The one interesting thing about Google's plan is that if you pay for 3GB of data and only use 1GB you will receive a credit for unused data. Issuing a refund for unused data could put some pressure on the competition who either make you lose unused data or if they are generous let you carry it over to the next month (up to a certain limit).
Overall I'd say the prices are pretty competitive, especially if you aren't using a ton of data. You can find out more over at Google's Project Fi website.
