Sending Long or Concatenated Messages

Our system will automatically split long messages and send them out in separate parts to be concatenated together when they reach their destination.

The charge for long messages depends on the number of parts the message needs to be broken into. If a long message needs to be sent as two concat messages then you will be charged for the two messages.

It should be noted that if a message is concatenated then the available length of each individual message is reduced to 153 characters due to the concatenation headers.

You should also bear in mind that some special characters like the Euro symbol (€) take two characters to encode and may cause a message which would appear to fit in one SMS to be split into two.

If a message should be split into two in this way then you will still be charged for each part.

For more information about this process please consult the HTTP SMS Specification Document article.
