If you need your phone or just about any device to have cellular connectivity, you need to have a SIM card. However, as easy as popping in a SIM card and getting connected to a network is, there might be hurdles along the way that might restrict your card’s functioning.
In this article, we’re talking about how to unlock a SIM card without knowing the PUK code.

Unlocking SIM cards without PUK codes
If your SIM card is locked and you don’t know the PUK code, your only option is to reach out to your telecom carrier and have them help you out. The first thing you should do is reach out to the carrier’s customer care service and provide whatever information they ask for to verify that you own the SIM card. Once the ownership has been verified, the carrier’s customer support agent will remotely unlock your SIM card.
Alternatively, you can also try visiting your carrier’s website and logging in with your account to check the PUK code there. Most carriers offer online accounts for customers to manage services and subscriptions as well as pay bills. These accounts also contain important information, including your PUK code that might come in handy in such situations.
Finally, if none of these approaches help you out, you can try entering basic codes such as 0000 or 1234 to see if they work. This approach might work, especially if you haven’t changed the default PUK code. That said, most SIM cards only allow for a specific number of tries before locking the SIM card completely, so you might want to be careful with your guesses.
Regardless, if you can’t figure out your PUK code and the carrier’s customer support service isn’t able to help (which is unlikely), your best bet is to get another SIM card with the same number or a completely new SIM card.
