This service is called broadcasting and is used by companies to contact groups of employees or by online services to distribute news and other information to subscribers. In addition to person-to-person messages, SMS can be used to send a message to a large number of people at a time, either from a list of contacts or to all the users within a particular area. The message will remain stored on your friend's SIM card until he deletes it. The message is stored in the SMSC (for days if necessary) until your friend turns his cell phone on or moves into range, at which point the message is delivered. The advantage of this method is that your friend's cell phone doesn't have to be active or in range for you to send a message. SMS is a store-and-forward service, meaning that when you send a text message to a friend, the message does not go directly to your friend's cell phone. SMS is also a convenient way for deaf and hearing-impaired people to communicate. SMS doesn't require you to be at your computer like e-mail and instant messaging (IM) do - although some phones are equipped for mobile e-mail and IM services. It is often less time-consuming to send a text message than to make a phone call or send an e-mail.

When a friend sends you an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to your phone as a little packet of data on the control channel. The control channel also provides the pathway for SMS messages. The tower also gives your phone a pair of voice channel frequencies to use for the call. When someone tries to call you, the tower sends your phone a message over the control channel that tells your phone to play its ringtone. Your phone also uses the control channel for call setup. Every so often, your phone and the tower will exchange a packet of data that lets both of them know that everything is OK. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around.
