Many people have probably heard the term SMS but have no idea what it actually is or what it stands for, and even less idea as to how it actually works. SMS short for Short Messaging Service is technology that allows people to send and receive text-based messages using mobile equipment, such as cell phones.
The younger generations have taken to SMS big time and have even started to create their own unique language and symbology for sending messages. This is a measure of how much SMS technology has been absorbed into youth culture. The possibility of a completely wireless worldwide web is becoming more and more of a reality. Mobile hand held devices such as palmtops are at the top of almost everyone's list of 'must haves'. These devices are now considered by more than half the world as essential, and not a luxury. The 'want' of the masses has now turned into a 'need,' and for some very good reasons.
SMS allows us more than just a way of keeping in touch. It is an extremely cost-effective way of communicating, allowing us to watch our budget in these times of economic worry. When using SMS, typing in just over one hundred and fifty characters takes up as much space on memory as one second on a voice-to-voice call. This can represent a significant saving to anyone. So long as the cell phone is switched on, SMS messages are usually received almost instantly. They are similar to e-mails in that they can be reviewed on the screen and can be stored in your own unique filing system for as long as you need them. SMS also offers the facility to send out messages to large groups of people with a single click of the 'send' button.
SMS has the facility for allowing different messaging formats for the user. It can be used for sending voice mail, for fax messages, as well as for e-mails. SMS allows users to collect all their messages in these formats from their mobile device.
Europeans have really adopted the SMS culture and send more than a billion messages each and every month. Incredibly, this same level of SMS culture does not yet apply to the United States of America. SMS service is way under-utilized in the USA, although it is growing. The main explanation of this unusual phenomenon is that the USA does not at the present time use the digital wireless interface standard used in Europe - GSM. Global Systems for Mobile Communication or GSM is the platform for all SMS communication.
Essentially GSM is a system based on digital technology, which is the reason that SMS features work so well. Most countries do use the GSM digital standard, but the USA is one of the few countries that prefer to use CDMA and TDMA rather than GSM. There are GSM networks throughout the USA but the general preference appears to be for the other two systems, which is somewhat odd since both these other systems reduce the capabilities of SMS. USA is starting to change to GSM but the change is relatively slow.
If you are wondering how such a tiny cell phone can hold so much information, most mobile devices can have SIM or Subscribe Identification Module cards fitted. These are essentially plastic cards with chips on which information is stored. If you are unfamiliar with the concept of SMS or have never used it, you really should give it a try. It is amazingly practical, extremely reliable and an affordable way to stay in touch with family, friends and colleagues.
