Talk to your operator’s customer support representative and ask him to disconnect your existing simcard… it’s the simplest way, no PC is required.

For the next time prefer an operator which is using COMP128v2 simcards & keep your pin1 enabled.

enable the Pin asking on the simclone like you would do on an original card.
After 10 wrong PUK entries the simemu will block to prevent the bruteforce "Puk" entering like an original simcards.

During initial programing the sim-emu firmware on the card, have the write protect ON and disable the Loader.

Simemu firmware is storing the important Ki in the CPU-eprom section so it's pretty secure of not being extracted in case you loose the simclone card.

Everything can be hacked/cracked/reverse engineered though (it's just a matter of time), in case you loose your simcard and you fear that somebody might make use of it, (IMO) better disable the simcards through the network provider.

original and clone (both) will be terminated, so dont worry, so do it right now,

CH@IN · 05-14-2006, 20:52

as pawaa says. The clone is an exact copy of the original. If you deactivate the original card, the clone won't work neither.

Even if you get a new "fresh" card from your Network provider with the same phone number and IMSI, the Ki will be ALWAYS different.
