Samsung claims thata ChatON now has a global subscriber base of over 100 million users. The service was launched in October 2011, hitting the 50 million subscriber mark in May 2013 and doubling that number to 100 million only four months later. ChatON's growth can be attributed to the support it offers across markets and various OS platforms. The service is accessible from PCs, Samsung feature phones, and all the major smartphone operating systems: Android, iOS, Blackberry and Windows Phone. ChatON's multi-screen support also allows users to sign-in on up to five different devices using one Samsung account ID.

ChatON also comes preloaded on most major GALAXY devices - the first of which was the GALAXY S III. Subsequent device launches include the GALAXY Note II, GALAXY S 4, GALAXY Note 3, GALAXY Gear and GALAXY Camera.

Samsung says that ChatON has also experienced steady growth in India, China and the United States, and is becoming increasingly popular in Europe and the Middle East.

The service currently supports 63 languages in major countries of the world. In India for example, ChatON has seen exponential growth as the service supports 10 regional dialects, with plans to support 13 dialects by the end of 2013. Additional features such as the Ramadan Anicon have helped boost its popularity in the Middle East.

ChatON has received positive feedback for its user interface features such as the ability to easily drag and drop media files into a chat window using the multi-window feature. Users can also create hand-written messages with S pen when using GALAXY Note 3.
