I got a Google Project Fi phone and sim card for testing about a month ago, with a phone I had so Google just opened it to more people. For a quick rundown it means a lower cell phone bill and more data. And it works overseas just like it works in the states at no extra charge. Verizon $10 per day charge is killing me and they limit the data you can use, it use to be whatever you had on your plan data wise you could use when traveling.
Long story short I’m going to be using the Google phone ( and number ) for the next month or so to see if the bill is lower. So if you need to contact me via text it might be delayed.
