   What is SMS?   

SMS is a service for sending text messaging. It is known as Short Message Service. You can send up to 160 characters (about 20 words) to mobile phones that use the Global System for Mobile (GSM) communication. SMS is similar to paging. However, SMS messages do not require the mobile phone to be active and within range and the message will be held for a number of days until the phone is active and within range.

The messages appears on the screen and they are an ideal way of providing 'two-way paging' between friends. One of the great advantages of SMS is that is is non-intrusive. You can send and receive messages at your own convenience.

Text messaging in the US is a 'non-event' since it requires digital networks and many American phones and systems are still analog. The digital networks that do exist are not compatible with each other. Americans also charge for mobile (cell) phone services, whether they make or receive a mobile call or send or receive a text message. They usually opt to pick up the phone and call someone.

In Europe and Asia messaging is cheaper because the carriers charge for the number of messages sent and not per-minute costs. Also the person who receives the call pays nothing (unlike US).

Some phones have 'predictive text' where the phone guesses a word as you type it, saving you from having to enter the whole word.
