Your phone number becomes a URL with GNum and make free calls to any GNum users.

GNum stands for Global Number. It converts your phone number into a URL/Call Link ([call_name]) which you can share it with anyone in the world! Use this GNum app to call any GNum registered users for free just by keying in their URL or call link.

You could also personalised your URL by registering with GNum. Place the call link in your email, social media accounts or any other platforms and anyone can reach you just by clicking on your link.

Unlike conventional VoIP applications which need internet connection on both sides, on GNum only the caller needs internet while calling through the web or the app. The call is routed through PSTN (public switched telephone network) and the receiver will receive the call through normal landline or cellular network.

At GNum, we value the voices of our users to deliver customer satisfaction. If you have any feedback, concerns or enquiries, please contact us by calling us with our support URL "" or email us at

GNum is currently available for mobile numbers in Singapore. We will be widening our geographical scope and to landline very soon. Follow updates on our Facebook page:
