Short Message Service (SMS): is a communication service defined as part of the GSM mobile communication system, with standard protocols that allow the exchange of short text messages among mobile phone devices. (SMS) delivered through cellular provider maintains for the end devices. The SMSC (short message service center) can send SMS messages to other devices with 140 octets as a maximum load. This determines the upper limit of a short text message to 160 characters using 7-bit encoding. You can probably go for other plans, such as 8-bit or 16-bit encoding, which reduces the maximum message length to 140 characters and 70, respectively (Brown, Shipman, & Vetter, 2007). The basic features of SMS includes message sending, receiving, reporting status, requests for command execution and replying.

SMSCs Works in two ways:

Store-and-forward: the system will store the message for some period of time to make sure it is delivered, if not then the system will resends the message again until it is successfully received.

Forward-and-forget: the system sends the message to the end device without assurance of receipt or an attempt to redeliver in the case of failure.

The SMS protocol a package has four layers: according to (Le Bodic, 2005)

The application layer: employed in SMEs in the form of software applications that send, receive, and understand the content of messages such as message editor and games. It is also known as (SM-AL) for Short-Message-Application-Layer.

The transfer layer: it consist some information about message length, message sender or receiver, date when received. The transfer layer is also known as the(SM-TL) for Short-Message-Transfer-Layer.

The relay layer: OR (SM-RL) for Short-Message-Relay-Layer allows the transport of a message through a range of network parts.

Link layer: as well as (SM-LL) for Short-Message-Link-Layer, it is the physical level of transmission process.

However, all these issues disappeared over the time by changing the system and by the end of 2000 the average increased to 35 per consumer per month.
