You just bought a new phone, excited to use it with a new SIM card. But your phone pops up with a request for a PIN code to unlock it. What’s that all about, and what do you enter? There are two main reasons why your phone might be asking for a SIM PIN or unlock code:
SIM Network Lock
The SIM Network Lock is a restriction placed by your phone’s original network provider, locking it to their network. It means you can only use the device with SIM cards from that specific carrier. Carriers use this to ensure that the phones they sell work only with their service. When you buy a subsidized phone, they want to ensure you stick around for the contract duration.
If you insert a SIM card from a different carrier, your phone will ask for a SIM Network Unlock PIN or Network Unlock Code (NUC). You’ll learn more about it in the upcoming sections of this article.
SIM Card Lock
SIM Card Lock is a security feature that protects your SIM card from unauthorized use on other devices. It requires you to enter a PIN (Personal Identification Number) to unlock the SIM card before you can use it.
The default PIN is usually printed on the back of the SIM card or its packaging. If you haven’t changed your PIN, use the 4-8 digit code provided by the carrier when you get your SIM card.
If you’ve forgotten the SIM PIN code, you can use the PUK (PIN Unlock Key) code to unlock the SIM and set a new PIN. The PUK code is also printed on the SIM card packaging, but be careful, as entering the wrong PUK code too many times can permanently lock the SIM card.
Not knowing the SIM unlock PIN code can be frustrating, especially if you want to switch mobile carriers. So, in the next part, we’ll explore whether it’s possible to unlock a SIM network-locked iPhone device.

Both the network unlocking code and PUK code can unlock your phone but for different reasons. The SIM network unlock code lets you use any compatible SIM card with your phone (useful for switching carriers).
Meanwhile, the PUK code unlocks your SIM card if you enter the wrong SIM PIN code too many times. You get the network unlock code from your carrier, and the PUK code comes with your SIM card or carrier.
