The technologie and the service is running, but the association does not 
end successfully. Do I need to set something else in connman? Where do I 
have to look?

The try to connect ends up with:
Error /net/connman/service/cellular_240075810199181_context1: Did not 
receive a reply. Possible causes include: the remote application did not 
send a reply, the message bus security policy blocked the reply, the 
reply timeout expired, or the network connection was broken.
