Hi!
Let's continue:
Hungary, Pannon GSM, 2002
NOT OK Prepaid
Hungary, Vodafone, 2002
NOT OK Prepaid
Hungary, Vodafone, 2005
NOT OK Prepaid
I think most of the cards from Hungarian Vodafone have no limit and the cards work after many hours Ki searching too, but the Ki cannot be extracted.
The cards from Pannon GSM are more protected than the cards sold by the vodafone because you aren't even able to read the card at all. Cardinal and other programs write: Unknown smart card error (during the reading process)
But I think it depends on the reader too.
