T-Mobile and Bobsled
T-Mobile has embraced free Wi-Fi calling whole hog. They provide an app called Bobsled to make free calls over Wi-Fi. You can call any US number. It works from any Android or Apple iOS device – not just phones, but computers and tablets as well. Surprisingly, this free service from T-Mobile does not even require you to be a T-Mobile customer; it works with any carrier. As of right now there are over 2 million Bobsled users, and T-Mobile says 95% of them aren’t T-Mobile subscribers For this reason, Bobsled is my number one pick for best way to make free WiFi calls on your smartphone.

But How’s the Quality?
I’ve tested Wi-Fi calling in a number of circumstances, and generally, the quality is pretty good – sometimes I’m aware of a slight delay, and some tinny audio quality, but overall comparable to what I get using my cell phone to make calls in the traditional way. And remember, making calls over Wi-Fi isn’t just about saving a few bucks by downgrading to a cheaper plan. Many people have poor cell reception in the places they use it most – in their own homes or at work – places where they might have an excellent Wi-Fi signal. If this is true for you, you might actually get better quality by making your voice calls using Wi-Fi.
