Dazu müsste man die Datensätze der Orginalkarten auslesen, was aber bei den meisten Karten nicht klappt, da dort ein relativ sicherer Algorhytmus verwendet wird. Das hat nur mit einem Musteralgorhytmus geklappt, den anfangs einige Netzbetreiber wie swisscom NATEL und D2 PRIVAT verwendet haben.
Mit heutigen Karten funktioniert das nicht mehr.
Scheinbar hast du recht. Ich habe zu einer 'baugleichen' 16-in-1-Karte folgendes gefunden:
The legislation of some countries forbids creation and/or use of clones GSM Sim- card (read laws !)
All backUp function support A3A8 COMP128V1 SIM Card only
This SIM Card Back-UP device doesn't support newest SIM Card that uses COMP128V2 algorithm to code KI key
Some GSM SIM Cards from 2001 (COMP128V1) are Scan-Limited. It has limited running scan times. If the scan is over the limit, the SIM Card will be locked and will not work any more. So don't scan the same SIM excessively if not necessary.
Hints to distinguish between V1 and V2 sim cards:
SIM cards issued before JUNE 2002 most likely are COMP128v1 SIM cards
Phone book capacity more than 250 entries most likely are COMP128v2 SIM cards
The assumptions made above based on my testing results with SIM cards available here in Hong Kong, it might not applicable on all SIM cards in different countries
When two or more SIM cards with same number (original and cloned) are in used:
Both phones can dial out but NOT in the same time
Only the latest dialed out or powered on phone can receives calls, the other
phone will not ring
If one phone is officially turned off (e.g. by switch off the power button), the
other phone can't receives calls even though it's still power on, the other phone
must make a call in order to make it can receives calls again.
