If the destination network is GSM, you can not submit more than 160 
text characters or 140 binary octets per SMS. The GSM standard clearly 
says this and it also says how to encode more than 160 chars into 
multipart messages. If your SMSC does that internally, fine, we do it 
already so the SMSC should simply accept our already correctly encoded 
packets and delivers them. If it doesn't do this correctly, blame the 
SMSC vendor. Apparently your SMSC belongs to the category non-standard 
which Kannel is not supposed to support.
