Google has expanded Project Fi's country compatibility list to 170 different countries now, making its Fi wireless service reach further than ever before and making it extremely easy to use it while you travel, since you literally have to do nothing to make it work other than make sure your mobile network connectivity is on when you land and get to wherever you're going. In regards to the countries that are now included with Project Fi compatibility on top of the initial countries that were already compatible prior to today's announcement, it's now possible to use Fi service in Guam, Nigeria, Morocco, Jordan, Belize, Uganda and many others, all of which you can see in the image below.
While 170 countries is a rather large list of countries for the service to work in, there are still many places where it won't work. Google has thought of this and to help people figure out if the service is going to work where they'll be traveling, whenever they book flights and hotel stays for travel, the Gmail information for any international flights that were booked will be analyzed by the Project Fi app, and then it will alert the user to let them know if the service will work in those areas, which eliminates quite a bit of hassle that a user might have to go through to find out. If the service won't work, users can easily find another solution for the time they'll be gone, and if it does work they can just sit back and do nothing.
With data being $10 a GB no matter where you use it, Project Fi has been a super simple carrier option for many subscribers. Google made it even simpler when it introduced the Bill Protection option, which now makes sure that subscribers never have to pay for more than 6GB of data used, as Google will now allow you to use over 6GB at no extra charge, though the speeds do slow down after a certain point so while it is free, it won't be as fast. All of the newly supported countries should be available to use the service in as of today, so any consumers traveling to any of the new locations will likely have no trouble keeping in contact through Fi while there.
