(Telecompaper) Deutsche Telekom's subsidiaries in Romania and Slovakia have launched Joyn apps, with support from Jibe Mobile. Marketed as Joyn powered by Cosmote in Romania and Joyn by Telekom in Slovakia, the service provides customers a single application to connect
via video call, text, instant messages and group messaging and share photos and videos over iPhone and Android smartphones. Jibe's IP Communication Cloud and RCS Hub support the services. The company demonstrated its support for RCS with Deutsche Telekom at the Mobile World Congress in February. Developed with support from the GSMA, Joyn is the brand name for Rich Communications Services. The new apps are the operators' attempt to compete with popular IP applications such as WhatsApp, Viber or Line.
