What is a good Wi-fi calling app?

Wi-fi calling app

I have a Galaxy S5, need an app to make & receive international calls over wi-fi. Looked into Whatsapp, but it appears to require both parties to have the app installed. Read about YouRoam, is it reliable? Would like my friends to be able to call me, even if they don't have the app installed. I live n US and I am travelling to Spain & Italy soon and will have access to wi-fi.

Have you looked into Google Voice using the Hangouts dialer? You'll have to give them a different phone number if you want them to call you on that app but you should be able to make calls over WiFi.

You can also set up a mobile number on Skype to send and receive calls with one phone number.
