SMS Spliting with EMS should be done in application. It's too hard to be
done in kannel, unless we implement the full EMS specification into it.

Then, to send multiple sms's, you should use the UDH field to say how
much parts and which message part you are sending.

You should look at 00 UDH Function, and do something like:
%00%03%00%02%01 
%00-UDH Funcion 00 - Multiple messages
%03-length
%00-Message number (use, for example, a random for your message and
should be the same value for each message part)
%02%01 - one is the maximum parts, the other is the part number (I never
remember which is each, but I guess it's MAX, Part number).

So, you'll send something like (assuming it's max parts first)
http://.....sendsms?...&udh=%XX%00%03%00%02%01%....
where XX is 5 + your message splitted part size
