Skype’s international VoIP phone calls for dirt cheap.

Try Viber out, I'm not that fan of Viber as a messaging app but for phone calls it was great value for the price.

I was looking for a solution when in Asia trying to call locally lines in Europe. I tried Skype first but the quality of phone calls was really deep shit. I was saved by Viber.
