SIM card hot swapping is really bad. I work at a Operator and you don't want to know what kind of network trouble this can bring.
I've also had the Kaiser for a couple weeks now, and yes, it is supposed to shut down when you open the SIM cover. It's just for your own protection, you can even break your SIM if you remove it while the device is on (and, has a electric current flowing to the SIM).
