Hi everyone, I found the following PDU and I would know the meanings of all bytes. The documentation I already found here was very helpful but some bytes remains totally mysterious for me. Here is the PDU: 00000000: 8c80 9831 3233 3435 3637 3839 3000 8d90 00000010: 972b 3335 3834 3032 3232 3232 322f 5459 00000020: 5045 3d50 4c4d 4e00 8918 802b 3335 3834 00000030: 3031 3131 3131 312f 5459 5045 3d50 4c4d 00000040: 4e00 9654 6573 7420 4d4d 5320 6d65 7373 00000050: 6167 6500 8504 3bd6 65f8 84a3 0201 3983 00000060: 5468 6973 2069 7320 616e 2065 7861 6d70 00000070: 6c65 204d 4d53 206d 6573 7361 6765 2077 00000080: 6974 6820 706c 6169 6e20 7465 7874 2061 00000090: 6e64 2069 6d61 6765 2e1d 83c3 6403 9e81 000000a0: 83ae 1780 8610 4a46 4946 0001 0201 0131 000000bo: 0131 0000 ffed 0de6 18 ...1234567890... .+35840222222/TY PE=PLMN....+3584 0111111/TYPE=PLM N..Test MMS mess age...;.e.....9.
