Hello Nickel, I had exactly the same problem while trying to use kannel with a mobile. I could first confirm that in case a wap simulatot hosted locally on my kannel server, kannel answer is fine. Then I understood this was a netwsork problem. Snoop data show that the handset was trying to connect again after a few seconds. In fact handset never got back kannel answer. After network problem was solved I confirm every thing is working fine.
Hope this will help. Antoine Garnier
