samsung galaxy s 3 – lLineague OS 17.1 – locked simcard – what did I do wrong?

I installed Lineague OS 17.1 on my Galaxy S3. Everything worked just fine until I put in my simcard. The first thing which happened after booting was getting directly asked for the PUK code although I didnt even enter a pin at all. So I just rebooted the phone again which made it not recognize the simcard anymore.
After that I put my simcard in my Galaxy S5 with stock ROM and I got the message that my simcard is permanently blocked.

Any idea what happened there?
