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 etc binary oriented messaging.

Why many countries dont have SMS rapid usage as this service is rapidly becoming as ingrained into modern culture as its voice counterpart.
