How to Unblock My MTN, Airtel, Glo, and 9MOBILE SIM Card

Unblocking your SIM card requires using the correct SIM PUK code. It’s an 8-digit code that you can easily find on the SIM packaging if you still have it. If you have a blocked SIM card that now asks you to "Enter PUK code” once you turn on your phone, you can easily unblock it by entering the correct 8-digit PUK code, as seen on your SIM pack.

But unless you’re a good keeper or recently bought the SIM card, chances are you’ve misplaced the SIM pack, just like any other irrelevant commodity. Nonetheless, you may still be able to retrieve your SIM PUK number if you’ve misplaced its packaging, usually by contacting your service provider or sign-in into your network operator's self-service platform or app. We've written extensively about how to get a PUK code to unlock your SIM card. You may need to read that first to learn how to retrieve your misplaced PUK number.

For now, here’s your straightforward guide on how to unblock my MTN, Airtel, Glo, and 9mobile SIM Card.

How Can I Unblock My MTN SIM Card?

MTN is arguably the most popular network provider in Nigeria, and they have supportive and easy customer service, too. So, you may be able to retrieve your PUK code effortlessly if you don’t have the SIM pack anymore.

To get the PUK for your MTN SIM card, I recommend chatting with Zigi, MTN’s personal assistant, rather than calling their customer care number. You can chat with Zigi via WhatsApp, Facebook Messenger, Telegram, or MTN's official website.

Here's how MTN users can retrieve their PUK number by chatting with Zigi on WhatsApp

  • Message +2349033000001 on WhatsApp.
  • Log in with your phone number or chat as a guest
  • Choose “Chat with an agent”
  • Tell the agent you want to retrieve your PUK number once they connect.
  • They’ll ask you a few security questions to confirm if you truly own the SIM card.
  • Answer the question sincerely and wait for a moment to get your PUK.

Simple? You should get your Personal Unblocking Key if you get most of the security questions right. Now that you have the key, simply re-insert the blocked SIM into your phone and use the retrieved PUK to unlock it.

However, if chatting with Zigi didn’t work, which is rare, you may contact MTN’s customer service line by calling 180 (or 08031000180 if you’re calling from another network).

How Can I Unblock My Airtel SIM Card?

Unblocking your Airtel SIM card is not any different from other mobile networks in Nigeria. First, you need to have your Aitel PUK ready by checking your SIM pack or calling Airtel customer service. If you don’t have the SIM pack anymore, you can get it through the simple steps below:

  • Dial 111 to call Airtel customer service from an Airtel number
  • Or, dial _+234802150011 if you're calling from another network.
  • Ask to speak with an agent, then tell them you need the PUK for your block Airtel SIM.
  • Complete the security questions to receive your PUK.

Once you have the PUK code, insert the blocked SIM card into a phone and enter the 8-digit code when requested to unlock your SIM. You'll also need to set up a new 4-digit pin code after unblocking the SIM.

How Can I Unblock My Glo SIM Card?

If you also can't get your Glo SIM PUK from its pack, you can contact their customer service.

Calling the Glo customer care line can be a mess and a total waste of time in most cases, so I'll recommend chatting with them online via their website, Facebook Messenger, or the Glo Café app.

Here’s how:

  • Go to on your mobile browser
  • Click on the chat bubble on the page to start chatting with an agent.
  • Tell them you need PUK for your SIM card
  • Provide your mobile number and complete the security questions to get your Glo PUK.

That’s it. You can now use the PUK obtained to unblock your SIM card.

How Can I Unblock My 9MOBILE SIM Card?

Similarly, you can contact 9mobile’s customer service to retrieve the PUK for your 9mobile SIM if you can’t find it on the SIM pack anymore. The customer service personnel with ask you a few questions that you need to answer sincerely to prove that you really own the SIM. After that, they'll provide your correct 9mobile PUK to unblock your SIM card.

Here's how:

  • Call 200 from a 9mobile line or +2348090000200 from another network.
  • Seek to speak with a customer care personnel and tell them you need your SIM PUK
  • Provide the affected phone number and answer the proposed security questions to get your Personal Unblocking Key.

It’s as simple as that.

Final Thoughts

The integral part of learning “how to unblock my MTN, Airtel, Glo, and 9mobile SIM card” is getting the right Personal Unblocking Key. Do you know that entering the wrong PUK ten consecutive times will damage your SIM card? Nonetheless, contacting your service provider may pave the way even if your line gets barred as a result of entering the wrong PUK.

After all, it might just be a nice move to avoid setting SIM card pin on your phone to avoid such a problem in the nearest feature. Most modern smartphones offer robust security options that are way better than SIM pin codes. So, stick to the security features on your phone and not SIM card lock.
