During today's IFA Preview Event in Munich, Deutsche Telekom, internationally better known a T-Mobile, gave an outlook of its upcoming RCS-e service which will be called "Joyn". During the presentation, Deutsche Telekom made clear, that Joyn is based on the GSMA's recommended RCS-e standard and will therefore be interoperable with other carriers, namely Vodafone, Telefonica, Orange and Telecom Italia, which were all part of the standardization process. This means, that Joyn will work across networks, as we know it today from SMS text messages. Furthermore, Deutsche Telekom unveiled, that it will start with chat, file transfer and video functionality and that a commercial availability is planned for October.
While chat and file transfer will be available free of charge for all users with a smartphone tariff, a data or SMS pack, video chat will be priced separately and all Joyn traffic isn't accounting into the inclusive volume of smartphone or data packs.
Also kind of interesting was another remark which seems to prove yesterday's information what Windows Phone 7.8 Windows Phone 8 differentiates from each other. On one of its slides, Deutsche Telekom mentioned that Joyn will become a native app on (upcoming?) Android and Windows Phone 8 smartphones, while older Android, iOS and Windows Phone devices will also get it as a stand-alone app.
Last but not least, Deutsche Telekom also said, that Vodafone Germany is expected to starts its RCS-e service a little bit earlier than Deutsche Telekom while O2 Germany will start with their version a little bit after Deutsche Telekom.
Only time will tell if Joyn will be the first successful service launch after such failures like UMTS video telephony, MMS and WAP but T-Mobile's pricing is the right step into a bright future. For charged services like video chat, Skype stays available anyway.
