anyone intersting in develop a SIM-free app?

[Guest meokey]

Does anyone here heard a kind of magic SIM card, in which there are multi-SIM cards KI/IMSI pairs? You may read your KI/IMSI pair from your original SIM cards from network carrier via a SIMcard-reader, and input the pairs into your magic SIM card. one application named SIMEMU in the card managers the multi KI/IMSI pairs, it will enable you switch your line among 10 SIM numbers, one to another easily and quickly.

Here is a profissional forum about this

Otherwise, a guy fix Simens SL45i with a patch named kvSIM which do the kind of thing and enables SL45i can switch the line among a real SIM card and 2 virtual cards in the patch.

Here is a page of kvSIM, and another page.

Don't you think it will be very convinient for you to switch between more than one numbers, such as number for business, for family, for friends???

MS Windows mobile system is much powerful than SL45i's. I believe such a applicaiton is also feasible. But I havn't seen such an applicaiton on smartphone yet. Do you intersting in develop it??? ;)

Of course, since the application "hook" the communication between the cell phone and SIM card, a real SIM card is not necessary indeed. and, the application can stores tons of encrypted pairs on the storage of smartphones even on the storage card, and switch quickly. Also, address book and SMS inbox should be moved to the storage and enlarged hundreds times than on SIM cards.

IMHO is impossible to emulate sim cards via software. The software you indicated clones two real sims in a real smart card. You need a smart card programmer for do this. I don't think that phone's firmware permits to bruteforce reading the sim and clone it.

Therefore, is quite illegal cloning sim cards, even if it's yours....

however is cool ;) in this way you can have free internet (read stewieforpresident last topic) ;)

but what if your operator discover it??? ehm... :P
