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.

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).
