Did you know you can make free calls to the USA and Canada using GMAIL? Yes, it’s absolutely free – you will not need to pay anything to make the calls and there are no restrictions in minutes or whatsoever. All this with a Gmail account only.
In order to make free calls to the USA, you, however, need to provide a one-time phone verification with Gmail. After you verify it, you can easily make tons of calls using Gmail, either from your PC, MAC, and even from the mobile using the HANGOUT application (for both ios & androids).
Please do let us know if you have any confusion.
