A user's SIM card is protected by a SIM PIN. The phone is stolen and the thief removes the SIM and inserts it into another phone. What does the SIM PIN protect against in this scenario?

• A.The card lock stops the carrier from porting the number to a different account (the operator checks the lock state before it processes a transfer request), leaving the subscriber protected against a swap performed at a retail counter by a persuasive caller
• B.The SIM PIN prevents the SIM card from functioning in any device until the correct PIN is entered, blocking the attacker from making calls, sending SMS (including SIM-swap verification texts), or using the subscriber's mobile data on a different device
• C.The card lock triggers a remote wipe on the original handset once the card is inserted elsewhere (the network signals the device management service), leaving the thief with a device that erases itself during the first attempt to use it on another network
