Message Payload

This field is part of the SMPP 3.4/5.0 Specification, and is used in place of the short_message fields to send messages up to 900 characters (byte size will vary based on encoding used.)

The message_payload parameter contains the user data. Its function is to provide an alternative means of carrying text lengths above the limit of the short_message field. Applications, which need to send messages longer than 140 bytes, should use the message_payload TLV.

When used in the context of a submit_sm PDU, the sm_length field must be set to zero

Field	Size Octets	Type	Value
Parameter Tag	2	Integer	0x0424
Length	2	Integer	Set to the length of User Data in bytes. Maximum byte length is 1800
Value	Variable	Octet String	Message User Data. Maximum size is 1800 bytes, and the message can be no more than 900 characters with encoding.

Submission Errors

An error ESME_RINVMSGLEN (0x00000001) - Message Length is Invalid will be returned if this value is greater than 1800 OR if the encoded message exceeds 900 characters.
