Discover the ways you can unlock your SIM card in this article.

SIM Card Packaging

The SIM card packaging includes all the details you need, including your phone number and the PUK code. You can find the PUK code in two places:

  1. On the first page of the plastic package that covered the SIM card
  2. On the back of the plastic card that the SIM card came out from 

You should see a 7 to 8-digit PUK code with a SIM PIN code in the mentioned places. The PUK code is usually labeled as such with the digits next to it. 

Network providers cover the PUK codes for security purposes. You can scratch this area with a coin or any edgy item to reveal the code. 

Calling Customer Care

If you lost the SIM pack or the network didn’t provide the PUK code on the package, you can call customer care. Carriers such as T-Mobile, U.S. Cellular, AT&T, Verizon, and others have their own support team that you can reach out to.

When calling, describe your concern, and they’ll give you your PUK code or generate a new one. 

Be ready to answer security questions to prove your identity. They might ask for personal details like address or date of birth. Just make sure that you are calling the right support hotline so you can avoid the risk of identity theft.  

Mobile Carriers’ Kiosks

Mobile carriers’ kiosks or carrier stores can also help you get a PUK code for your SIM card. They will have to ask for your details to prove your identity. Be ready to provide them when asked. 

Carrier Website

Many mobile carriers offer online accounts to their customers. You can enter your credentials into the mobile carrier website if you have an account. Your profile should include your PUK codes. Websites also have chat support or email support that you can reach out to unlock your SIM card. 

Unlocking Your SIM Card 

Once you have your PUK code, you can then use your PUK code to unlock your SIM card. There are several ways in which networks ask for your PUK code. Generally, you can follow these steps: 

  1. You might need to attempt to make a phone call
  2. Enter the PUK code when the network prompts. 
  3. Your device will show instructions on creating a new SIM PIN. You must enter it twice. 

But when the network doesn’t prompt you to type in a PUK code, you can do these steps instead:

  1. Open the phone dialer and call **05*[PUK]*[New PIN]*[New PIN]#.
  2. It will say “PUK,” and then you can enter the PUK code.
  3. “New Pin” will show you can enter your new SIM pin. You must enter it twice. 

It might differ from each network. It would be helpful to check their websites or call their customer service if needed.
