DT Delays joyn Launch

Deutsche Telekom apparently has delayed its launch of the “joyn ” messaging service. Joyn originally was scheduled to launch in December 2012 but DT apparently has run into implementation issues.

Joyn, the GSMA-backed effort to create a carrier over the top messaging service, will allow DT customers to chat and send files, free of charge,  on all smart phone tariffs, at no incremental cost incurring data usage charges, for all customers who have a calling plan with flat-rate data usage or text messaging plans.

Some have questioned whether joyn really will be able to compete with WhatsApp and other over the top messaging services, but the retail packaging plan DT has chosen is intended to make joyn usage an amenity for users who already are paying what DT considers to  be reasonable amounts of money for voice and messaging usage.

Smart phone adoption is driving mobile service provider mobile broadband revenue. But smart phones also are cannibalizing service provider voice and messaging revenue.

In 2012 the increase in smart phone penetration will cause voice and messaging revenue erosion of 3.9 percent in Western Europe and 1.6 percent erosion in Eastern Europe, according to Informa Telecoms & Media.

In fact, every increase of 10 percentage points in smart phone penetration in a given market costs Western European operators a 0.5 percent loss of voice and messaging revenue, according to Informa calculations.

Joyn is a service made possible by the “Rich Communication Suite,”  essentially messaging applications built on IP Multimedia Subsystem (IMS) standards.
