For those having a Blackberry (I tried it for a Blackberry Torch and it
really works:) the following link
http://www.zibri.org/2009/08/hidden-things-are-usually-best.html enables
Engineering mode. Follow the instructions and instead of the Help screen the
engineering screen is displayed. Under Utilities there is a SIM monitor
allowing to display SIM_Kc or USIM_Kc depinding on the type of SIM you use.
There is an impressive set of tools and different monitor functions ranging
from neigbour cells, System Information messages to Wifi and security
related settings.
