Google's Project Fi
Google's new wireless phone service, Google Fi, is simple. Unlimited minutes and texts for $20/month and pay for only the data you use. The catch? It'll only be limited to select areas (Google rarely releases a product/service to everyone at first) and it'll only worked with one phone, the Nexus 6, for now. The coverage will use T-Mobile's and Sprint's networks which is interesting since they use different technologies. It will also include millions of WiFi hotspots but we don't know much about that. Google promises smooth connection transitions between the various networks. Google Voice like features come native to Project Fi users as you can get messages using your computer and other devices.
At $10/GB, it's pretty expensive considering you can get unlimited data from T-Mobile for $80. It is cheaper than the Verizon 1GB/2GB plans at $60/$75; Google Fi (sounds like Googlify, the verb I just made up), would be $30/$40. As a user that averages around 30GB/month, that would cost me $320 a month with Google Project Fi...
Google Project Fi will have a market though, low usage users (under 5GB). It's definitely something worth trying but $10/GB seems a bit expensive for what seems to be an experiment for Google.
