Who can I make phone calls to?
Google uses Voice over iP (VoIP) technology. Because of this, you can call any other Hangouts user on their computer or mobile device BUT you can also make free calls to just about any phone (mobile or land line) in the US or Canada from anywhere in the world (with just a few exceptions like Mexico and Argentina. (If the number you call isn't free, it's only 1 cent/minute.) Calls to destinations outside of the US are at very low rates. Learn more...
