Hi Michaelp,

For the moment, the only way to determinate if one SIM uses COMP128 v1 or V2 is make a search Ki by collisions (normal method of SIM SCAN, cardinal or XSim.

If there aren´t collisions this card are COMP128 v2.

Normaly, All COMP128 v2 are 32k but not all 32k are COMP129 v2.

Best Regards,
Sir Graham.

Thanks SirGraham!

This SIM card has 64k (mentioned in invoice).

Well I'll wait till COMP128-2 will be crecked.
Also simemu has to have possibility for every number set ciphering algorithm (COMP128-1 or COMP128-2).

Good luck.
