Re: splitting messages

The reference number should not be confused with message id. A same reference number in UDH of multiple short messages identify them as part of same long message, so in such a case you will have same reference number in all segments of a long message whereas every such segment shall be assigned a unique message id.

Also in this case, ETSI GSM Specs 3.40 clearly define that "Each concatenated short message contains a reference number which together with the originating address and Service Centre address allows the receiving entity to discriminate between concatenated short messages sent from different originating SMEs and/or SCs."

Also I couldnt understand what purpose it would solve to send op logo with different originators?

  well there is a sort of message id inside the udh ..its the concatenated short message reference number ,.. there is no need to use the short number

  of course smsc won't complain about it...
  every message for smsc is separate, it does not try to reassemble 
  messages , it just sends the parts which are actually totally separate 
  short messages;
  reassembling of messages is made on phone itself, and i am 99% sure that 
  what you are trying to do can't be done;
  phone just assumes it got first part of one thing and second part of 
  another thing; while the originators differ it would mean that two 
  different originators sent their messages, though none of them delivered 
  both parts;
  that is because there is actually no message id inside the udh...

  So, theoretically, [i did not try this actually] one would be able to 
  send two operator logos to one phone and (with some unpredictable delays 
  that happen during delivery) get both logos broken (mixed) on the phone...
