Abstract: The method of the invention for sending a message batch download in a telecommunication network comprising a sender entity, one or more receiver entities, and intermediate entities there between, is mainly characterized by creating a test message and sending the test message to each receiver, receiving an acknowledgement in case of a successful delivery of the test message sent, creating the real message to be sent to said receiver(s) and submitting the real message in batches.
