Leading companies in telecommunications agree that Multimedia Messaging Service will build on the success of SMS services

(June 18, 2001)

In a unique initiative CMG, Comverse, Ericsson, Logica, Motorola, Nokia and Siemens unveil a common vision for Multimedia Messaging Service (MMS). The objective is to raise overall awareness of MMS and to ensure consistent market development into an open global market.

MMS is driven by active individuals creating content and sharing experiences through multiform communication that combines new forms of rich content, such as audio and video clips, photographs and images with text messaging. MMS adds new functionality and new content types in small steps that consumers will readily understand and enjoy. This will lead to rapid adoption and penetration of the service.

Each of the companies believes MMS will be a key mass-market service for mobile operators, content providers, application developers and advertisers alike. Owing to the rapid uptake of messaging services by various market segments, the concept of MMS is appealing for all users. In addition to MMS being a key person to person service, it is also a bearer for media content and other applications.

SMS services have been the fastest growing mobile data services with notable impact to operator's revenue and profit. According to the GSM Association, the worldwide SMS traffic amounted to 15 billion messages in December 2000. MMS will offer a natural and successful evolution of the SMS business model, generating new revenue streams from existing customer base and attracting new customers. Messaging in the form of MMS will lead the way to profit in 2.5/3G just like SMS has done in 2G.

MMS is a 3GPP and WAP Forum standardised service that can interoperate with existing mobile SMS devices and other messaging applications. MMS can be seamlessly integrated into existing services and brought directly to a large customer base. By planning the MMS implementation today, the early movers will be well positioned to take advantage of 2.5/3G technologies and applications.
