What’s GNum?

GNum (also known as Global Number) is a calling app that converts your phone number into a click-to-dial URL so you can stay in touch with the people who matter!

How is GNum different and how does it work?

Conventional calling apps require both parties to be connected to the Internet. With GNum, only the caller needs data or an Internet connection, and the receiver will answer as if it is a normal voice call. With only one party dependent on an Internet connection, GNum calls are clear and stable.

How can I get a personal GNum URL and what’s a CallName?

Every user will be given a unique URL upon registration with GNum. A CallName is an option to personalise your name at the end of a URL. For example, if your CallName is “Adam”, your personal URL would be “www.gnum.com/adam”.
