(Telecompaper) Deutsche Telekom announced Immmr, a service for mobile numbers as an independent, open communications service for voice, messaging and video telephony that will launch in the second half of this year. The service makes mobile phone numbers virtual, meaning they are no longer tied to a specific device or SIM card. Immmr will initially be available for download as a free app from the App Store and Google Play. The service developed by the Deutsche Telekom's R&D department T-Labs in Berlin is being tested in selected European countries.
