SIM security prevents unauthorized access to your SIM card. It provides additional safety denying access to your SIM in case you lose your phone, or it’s hacked.

Activate SIM Security now by following these simple steps to lock your SIM:

On your Android phones:

  • Go to ‘Settings’.
  • Click ‘Security & Privacy’.
  • Click ‘More security settings’.
  • Tap ‘SIM card lock’.
  • Toggle on ‘Lock SIM card’ slider.
  • Enter your current SIM card PIN (default PIN is 00000)
  • This will prompt you to change your PIN (Change to a unique 4-digit PIN)
  • Confirm your new PIN again and you’re done!

For low-end feature phones:

  • Go to ‘Settings’.
  • Click on ‘Setup SIM card lock’.
  • Click on ‘Lock SIM card’.
  • Insert your desired pin.
  • Input your *PUK number if required.
  • Confirm your pin and your SIM is locked.

 

And For iPhones:

  • Go to ‘Settings’.
  • Tap on ‘Cellular’
  • Click on ‘SIM PIN’.
  • Toggle on SIM PIN
  • Enter your current SIM card PIN (default PIN is 00000)
  • This will prompt you to change your PIN (Change to a unique 4-digit PIN)
  • Confirm your new PIN again and you’re done!

If you input the wrong SIM card PIN 3 times, it will request for a PUK.

Once you enter your PUK number, you’ll be prompted to change your PIN.

Your SIM card PIN is Personal. It is a secret number known only by you. Do not share it.

*PUK is the Personal Unlock Key – a unique code linked to your mobile phone’s SIM card and is 8 digits long. You can locate the PUK on the starter pack of your SIM card. If you can’t find it, please call 300, chat with Zigi, or visit any MTN shop.

Once the SIM card lock is active on your phone, you’ll be required to enter your PIN anytime your phone is switched on or restarted. If the phone is stolen and the SIM card is placed into a new phone, it will request for the PIN.
