Can they do this without connecting to a cell tower? Otherwise, the carrier would notice the pairing of your SIM to the new IMEI, and further security steps would be possible.
- gruez 3y agoWhile what you described is theoretically possible, I've never seen any mobile provider implement it. The reason is fairly simple: if you cared about the security of your sim, you'd set a sim pin. If you don't, you don't set a pin. Requiring reauthentication every time your IMEI is going to cause a massive increase in support calls for very little security gain.
