How to protect your MTN Sim from being accessed by a third party?

Wondering how to protect your SIM card from being hacked by cyber criminals or any other unauthorized personnel that might accidentally gain access to the sim card either because the sim is lost or stolen? Follow these simple steps to lock your MTN SIM card:

On the home page of your mobile device:

  • Navigate and click on Settings.
  • Scroll to select Security.
  • Click on configure SIM card lock.
  • Click on the “Lock” SIM card.
  • Insert the default PIN code of the MTN SIM card (which is 00000).
  • Press “CHANGE SIM card PIN code” to replace the default PIN code with your unique 4-digit PIN code.
  • Confirm your unique 4-digit PIN code.
  • Switch off and on again to check if the SIM PIN code is activated.

Note that you will always receive a prompt to insert your SIM PIN code every time you remove and insert your SIM card into a device or turn on your device, and the above process will only apply if you have never changed your SIM PIN code. If you enter the wrong PIN by mistake and your SIM card asks for a PUK code, enter the correct PUK code if you have it.

Can’t find your PUK code?

Locate any MTN store nearest to you and visit them, dial 180, or get in touch on their social media client support media (Facebook: @MTNLoaded, Twitter: @MTN180) to avoid destruction to the SIM card.

If you lost your sim card, the individual that will use the sim card for crime will most of the time put it off first and once he/she put it on again, there will be a need to enter the sim card pin of which the person will always want to guess. Once the individual enters the wrong pin 3 times, the sim card will be blocked.
