Possibly the AT driver has not finished connecting (initializing the 
modem) yet, and so is not trying to handle the messages. once you put 
in the SIM, the driver completes initialization and delivers the 
messages.

I suspect that if you pull out the SIM after kannel has completed 
initialization of the modem, then further messages sent will be 
rejected by the modem (as it can no longer use the network) and will 
receive a NACK status from kannel.
