Is Google’s Project Fi worth a try?    I’m Fred Fishkin with technology BootCamp, a report on gadgets and gear.   Google has partnered with T-Mobile and Sprint to offer a mobile phone service that uses WiFi whenever possible and one of those two mobile networks when necessary.   Initially…you have to request an invitation from Google and either own or be willing to purchase a Nexus 6 smartphone.  So jumping in is taking a leap of faith.  The Nexus 6 is one big phone….but if you’re a fan of the Galaxy Note or iPhone 6 plus…you’ll feel pretty much at home with it.   The pricing is innovative too.  The basic service for unlimited voice and texting costs 20 dollars a month with data priced at 10 dollars per gigabyte.   And you only pay for what you use.   Project Fi is a no contract service and allows you to use your phone as a mobile hotspot tapping into the data you pay for.  I’ve been taking a look and so far I’ve been impressed with the coverage and with the phone…although I wish it had a user replaceable battery and a memory card slot.   You can find us at BootCamp.com.   I’m Fred Fishkin.
