Do these "Super SIM" cards work?

Don't waste your money on those. They can only emulate the first generation of SIM cards used before 1999 and only by some (few) companies. With the original GSM design came a proposal on how to implement security. Instead of using their own brain a few companies actually used this propsal. The CCC (Chaos Computer Club) demonstrated first how the hack works. In Germany only D2 (today =Vodafone) used COMP128V1 but soon changed to better security. No German SIM today will work with this "Super SIM" the same is true for most other countries on the planet.
