What Is a SIM PIN?

A SIM PIN (Subscriber Identity Module Personal Identification Number) is a security feature that locks your SIM card with a unique PIN code. This ensures that even if your SIM is removed and inserted into another device, it cannot be accessed without the PIN.

Why Set Up a SIM PIN?

Setting up a SIM PIN provides:

• Protection Against SIM Swapping: Prevent unauthorized use of your SIM card.
• Security for Phone Calls and Messages: Blocks access to your phone number and text messages.
• Added Layer of Security: Ensures SIM-based services like two-factor authentication (2FA) remain safe.
