How to protect your sim card in case it gets stolen
You don’t have to wait for your sim card to be stolen to start looking for ways to block MTN sim cards. You can deny anyone access to your sim card at all times, ensuring that even if the sim card gets stolen, the person will not be able to use it because they can’t access it.
This is done by putting a pin lock on your sim card, so whenever your phone goes off and on again, the pin will be required. If the sim is put in another phone, the pin will be requested.
To set up your sim card safety pin:
- Go to your phone settings
- Select Security
- Select ‘configure sim card lock’
- Select ‘lock sim card’
- Input the MTN sim card default pin (found on your sim pack)
- Select ‘change sim card pin code’ to input your new 4-digit pin code
- Re-enter the pin to confirm it.
- Finally, turn your phone off and on again to confirm the activation of the pin. If it’s active, a pin will be required before you can access your sim card.
Remember to always remember your pin, as three unsuccessful attempts will prompt the PUK number to be requested. If you cannot input your PUK number (found on your sim pack), your sim card will be blocked.
