Concatenating a message is a way of getting around the 160 (70 Cyrillic or Unicode) character limit. Applications, and most mobile devices, can write SMS messages longer than this limit. In order to send them, the device divides the message into two or more smaller ones that fit within the character limit. Each of these is charged as its own message. The messages can then be recombined by the receiving device and displayed either as a long message, or several shorter ones.
