Project Fi - A wireless service from Google

I have been traveling through a bunch of countries with this service, and I must say I'm super happy.

Some highlights:

1. It works perfectly with my iPhone 7 Plus (Calling, 4G, hotspot)

2. Since it's roaming free, it always swap to the provider with the best reception

3. fi.google.com/account is really intuitive.

4. Support replies within 1 minute

5. It comes with a free data sim

I have been using this service for about an year. It is extremely spotty when compared to AT&T etc, but I am sure it will improve over the next few years
