I so rarely use voice, especially when traveling, that the potential problems someone might encounter with needing to make/receive voice calls aren't what immediately comes to mind.



The app allows you to make voice calls to real numbers if you have Google Voice set up on your account. You may need to sign up for Google Voice (voice.google.com) first; I don't know. Once it's set up, tap the icon that looks like a keypad to make calls to numbers.

Hangouts voice is disabled in some places but not others. It was not blocked for me in Korea. It was blocked in Taiwan (as well as, obviously, the PRC--they don't like Google at all there).

Skype may be more flexible but, as I mentioned, a tad more expensive (a higher fixed cost for a phone number plus calling rates are a bit more but still far cheaper than roaming rates). I didn't try Skype, though--I have a cheaper home-brewed VoIP setup through a wholesale provider and a custom app on my phone, so that's what I used when Hangouts didn't work for me.
