Understanding the use of the SIM card PIN
Your SIM card PIN (Personal Identification Number) is a 4 to 8-digit password that is required to activate and unlock your mobile phone. Protect your data from unauthorized access in case your device is lost or stolen. Additionally, the PIN acts as an additional barrier to security vulnerabilities and helps maintain control over stored information.
It is essential to remember Entering an incorrect PIN three consecutive times will automatically lock the SIM card. To unlock it, you will need a PUK code (PIN Unlock Key) provided by your mobile service provider.
