Hi Everyone,

Just want to ask a question that has been bothering me for quite some time:

Although I have read it many times that Apple can block the x-sim solutions if they please I would like to ask how? I understand that some of the cheaper cards all use the same ICCID and that apple could easily block that ICCID and they would stop working, but the stealthsim uses the operator code of att and then the rest of the numbers on your sim. So the first numbers are for at and t and then the rest are off your sim card making a "unique" iccid. Since every stealthsim user has a seperate iccid how can they block its use? Am I missing a piece of the puzzle?

edit: I did a little bit more research and am unsure but believe it would be done with the IMSI, although im not 100 percent sure.

apple cant block them its up to at&t
if apple wants to block it they would need to mod the hardware somehow on brand new iphones

They (Apple) can't block your existing solution, but they can stop this from working in future firmwares. This as the SIM solutions only emulate the AT&T network ID the first times it is requested, because those are the times the iPhone asks this for its own purpose. Later the phone asks for this information on behalf of the network, and at that time the real network ID must be provided, otherwise the SIM won't work. Thus I believe it is easy for Apple to prevent this from working in future firmwares by asking for the network ID more frequently and during the entire operation of the iPhone.
