Currently, camel-smpp splits a long message into 140 byte SMS messages to go over the network. This is done automatically for any long message.
Not all networks support these split messages. Some networks drop the subsequent frames after the first, some don't delivery anything.
It would be useful to give users of the component the ability to set a message splitting policy, e.g. to refuse to split messages and throw an exception if a long message is encountered. This will reduce load on the SMPP provider and may also avoid costs associated with messages that are never delivered.
