Mint Mobile vs. Google Fi: Which wireless is best for you?
Mint Mobile comes out ahead in terms of value

Google Fi is a fairly well-known MVNO carrier among Android fans, especially those traveling abroad. Its plans aren't that dissimilar to those of many other MVNOs, with a high-speed data cap on its unlimited plans and the T-Mobile network providing the majority of the carrier's coverage. But it also has quite a few nice software features, even for iPhone users. Google Fi even supports multiline savings on all of its plans, so you can bring the whole family along.
