Latest News Links Zone Feedback Zone Site Map Concatination Zone Concatenation is the process of stringing several short messages together as a group. Up to 255 short messages can be concatenated.
Every short message contains additional information outside the short message text itself.
One of these information fields, the User Data Header Indicator, is used to signal that concatenation is being used, which set the concatenated short message belongs to, how many concatenated short messages are in that set and where the concatenated short message belongs in the complete sequence. This enables the receiving application to put the concatenated short messages back together in the right order and determine whether all the short messages have been received. Mechanisms for handling such errors are therefore at the discretion of the specific application software. Concatenation can in theory be used for any application that requires more than 160 characters of information transfer. However, SMS was not designed for high volume information transfer.
