Does 160-character Long Message Change Mobile Communications?

Short message service (SMS) is a globally accepted wireless service. It enables the transmission of alphanumeric messages between mobile subscribers and external systems, like electronic mail, paging and voice mail systems. This store and forward service provides you 160 characters to be used for numbers and alphanumeric symbols. It is easy, fast, and convenient and cheap - what else could be expected from the communications means of the third millennium?

Since its introduction, the history of SMS has been a success. It has a global presence, and only in Finland, the number of sent short messages increased by a factor of 20 from year 1997 to 1998, and the pace is still accelerating. People are replacing traditional mobile-to-mobile phone calls by short messages and short messaging is changing our communications habits. One needs to be capable of sending pictures, notices and committing daily tasks faster and more personally - with one's own mobile phone. This opens many possibilities to service providers.

Technically, the Short Message Service is a store and forward service, which means, short messages are not sent directly from sender to recipient, but always via an SMS Center, instead. Each mobile telephone network that supports SMS has one or more messaging centers to handle and manage the short messages. The Short Message Service features confirmation of message delivery. This means that, unlike paging, users do not simply send a short message trusting and hoping that it gets delivered. Instead, the sender of the short message can receive a return message back notifying them whether the short message has been delivered or not. Short messages can also be sent and received simultaneously with GSM voice, Data and Fax calls.

In this highly competed communications sector, SMS provides means for operator to benefit of this boom. Since it is important to differentiate from one's competitors and create some extra value to one's customers, SMS offers an excellent way to do this. SMS enables the service provider to increase call completion, and so to improve the service provided. By providing specialized services, the operator can gain a significant competitive advantage over its competitors. These new ventures are normally pretty low-cost to realize, and once introduced, they pay themselves back pretty fast.

SMS provides many useful services to end-users; from traditional messaging to fancy applications. The most important comes first - SMS is a means of person-to-person messaging. Using short messages you are also able to customize your phone; just select a ring tone, send a SMS and, voila, you are equipped with a new ring tone. SMS allows you to be updated on your emails, flight ticket reservations and just chatting with a group of your friends. You are able to order ordinary goods and even commit your daily tasks, like banking. This will only be the beginning of a long conquer story.
