How To Unblock MTN SIM Card

Using The PUK Code

The most common method to unblock your SIM is by using the PUK (Personal Unlocking Key) code. Here’s how:

• Find Your PUK Code:
  1. Check the cardholder that came with your SIM; the PUK code is printed on it.
  2. Alternatively, log in to the MTN mobile app or website to retrieve the code.
• Steps To Unblock:
  1. Enter the PUK code when prompted.
  2. Choose a new PIN code.
  3. Confirm the new PIN by entering it again.

Tip: Be careful when entering the PUK code. If you enter it incorrectly more than 10 times, the SIM will be permanently blocked.

Contacting MTN Customer Care

If you cannot access your PUK code or face other issues, contacting MTN’s customer support is a reliable option. Here’s what to do:

• Dial 180 (within Nigeria) or +234 803 101 0180 (outside Nigeria) on another phone.
• Select the option to speak with a customer service representative.
• Provide the following details:
  • Your phone number.
  • SIM serial number (printed on the SIM card).
  • National ID or other proof of ownership.

The support team will guide you through unblocking your SIM.

Using The MTN Mobile App

For tech-savvy users, the MTN mobile app offers an easy way to unblock your SIM. Here’s the process:

1. Download the MyMTN App from the Google Play Store or Apple App Store.
2. Log in using your MTN number and OTP (one-time password).
3. Navigate to the SIM Services section.
4. Select the “Unblock SIM” option and follow the on-screen instructions.

This method is convenient as you can resolve the issue without calling or visiting a service center.

Visiting An MTN Service Center

If the above methods don’t work, visiting an MTN service center is your last option. Follow these steps:

1. Locate the nearest MTN office through the website or app.
2. Bring along:
   • A valid ID card (e.g., National ID, driver’s license, or passport).
