Mocha Messenger, an over-the-top (OTT) service that provides free Internet-based calls and messaging for users, reached some 10 million of users by the end of October, two years after its launch.

The service, developed by Viettel Telecom, a member company of Viettel Group, offers free in-bound calls for subscribers who are students. Students do not need to have 3G or 4G access to use the free calls.

Viettel Telecom also upgraded its appearance to provide a more friendly and easy-to-use experience.

Notably, it integrated its online money transfer service Bankplus on Mocha to enable users to transfer money during their talks. The application is available for both Android and iOS.

Besides basic functions such as text messages, group chat, voice calls and photos, the service allows users to listen to music together on the social networking site integrated in the application. — VNS
