Short Message Service


The Short Message Service (SMS) is a paging service to send short messages to mobile telephones. SMS started as a service within the GSM network. Nowadays, a number of other systems for mobile communications offer the same service.

A Short Message Service has a length of 1120 bits. This gives the possibility to send and receive text messages of at most 160 characters or data messages of at most 140 bytes. However, it is possible to join a few messages to one larger message.
