This section covers messaging technologies: SMS, MMS.
Short Message Service ( SMS) :
Short Message Service (SMS) is the ability to send and receive short alphanumeric messages to and from mobile telephones. SMS can also be used as a transport for binary payloads and to implement the WAP stack on top of the SMSC bear. SMS was created as part of the GSM Phase 1 standard. SMS allows users to directly transmit messages to each other without the use of an operator (it is, however, necessary to have the underlying operator controlled wireless service). The first user can send a message to a mobile unit, via a direct connect computer. The SMS protocol of messaging is also "smarter" then standard paging. SMS is a store and forward method therefore, if the end user is not available, the mobile unit is powered off, or the unit is outside a service area, when the unit comes back on line the message will appear. A SMS message can also be sent "certified," where it will notify the message originator of the end user's receipt of the message.SMS appeared on the wireless scene in 1991 in Europe. The European standard for digital wireless, now known as the Global System for Mobile Communications (GSM), included short messaging services from the outset. In North America, SMS was made available initially on digital wireless networks built by early pioneers such as BellSouth Mobility, PrimeCo, and Nextel, among others. These digital wireless networks are based on GSM, code division multiple access (CDMA), and time division multiple access (TDMA) standards.
Network consolidation from mergers and acquisitions has resulted in large wireless networks having nationwide or international coverage and sometimes supporting more than one wireless technology. This new class of service providers demands network-grade products that can easily provide a uniform solution, enable ease of operation and administration, and accommodate existing subscriber capacity, message throughput, future growth, and services reliably. Short messaging service center (SMSC) solutions based on an intelligent network (IN) approach are well suited to satisfy these requirements, while adding all the benefits of IN implementations.
Enhanced Messaging Service (EMS ) is basically is an extension of Short Message Service, which enables the ringtones, wappush, mms notifications, SIM toolkit applications etcd binary oriented messaging.

Multimedia Messaging Service (MMS):
The Multimedia Messaging Service (MMS) is a new, versatile messaging service that can carry multimedia content, including images, video and audio clips, maps, graphs, layouts, ground plans, cartoons, animations, etc.
Today's popular text-based Short Messaging services and Smart Messaging services can be enhanced with richer MMS content. MMS also offers a radically better end-user experience compared to text only-based short messaging services. For example, a weather service can be extended from text-based information to include animated weather maps and forecast graphs with MMS capable terminals. Personalization will be more effective with such as new audio formats and color screens.

MVNO: is a GSM phenomenon where an operator or company which does not own a licenced sprectrum and generally with own networking infrastructure. Instead MVNOs resell wireless services under their brand name, using a regular telecom operator's network with which they have a business arrangements. Usually they they buy minutes of use (MOU) from the licenced telecom operator and then resell minutes of usage to their customers of MVNO. Currently MVNOs are emerging in fast pace in European markets and beginning in USA also. Slowly MVNO phenomenon catching up in Asia and other parts of the world also.
