    Hi!

    Udh: How sohuld the udh look?
    Body: And the body?


    Im trying with this UDH: 0B0504158a0000

    And the body: 00030C0201E8329BFD4697D9EC37

    where 00030C0101 is the concatenated part...

    And on the 2:nd message the body is 00030C0202E8329BFD4697D9EC37

    I endup with 'the message cannot be displayed' i have a Nokia 6510.

    I am lost... i cant find more useful information

    RE: Multipart SMS.

    User data header indicator (bit 6) has to be set in the First octet of
    SMS-SUBMIT:
    51 First octet of SMS-SUBMIT Description below
    bit 7 0 TP-Reply-Path Reply path not set
    bit 6 1 TP-User-Data-Header-Indicator Indication that user data contains an additional header
    bit 5 0 TP-Status-Report-Request Not requested
    bits 4,3 10 TP-Validity-Period-Format Relative format
    bit 2 0 TP-Reject-Duplicates Do not reject duplicates in SC
    bits 1,0 01 TP-Message-Type-Indicator SMS-SUBMIT type

    Then user data header in the beginning of 1. user data:

    05 Length of the User Data Header
    00 Information Element Identifier (IEI; concatenated short message, 8-bit reference number)
    03 Information Element Data Length (IEDL; 3 octets)
    01 Information Element Data (concatenated short message reference number)
    02 Information Element Data (total number of concatenated messages (0-255))
    01 Information Element Data (sequence number of current short message)

    Then user data header in the beginning of 2. user data:
