A SIM PIN code is a number, usually four digits long, that is used to how to Unlock Any SIM Card. Your carrier gives you the code, and some of them let you change it. When you turn on your phone or when you lock it yourself, you’ll need to unlock your SIM card. To do this, you type the code into the pop-up window that appears when you turn on the phone screen.
A SIM PIN code is a way to make sure that no one can use your SIM card without the right code, just like a lock screen PIN code. When you put a SIM card with a PIN into a phone for the first time or lock it by hand, you’ll need to know the PIN to use it. This makes sure that the card can only be used to make calls or send messages by people who know the code.
Steps to Unlock Any SIM Card
- Enter your SIM unlock code. If you locked your SIM card, you will be prompted to enter the password when you insert that SIM into a new phone. If you know the password, enter it to unlock your SIM.
- Get the PUK for your SIM. This code comes from your mobile provider, so you’ll need to contact them directly. Your provider may ask for the number on the SIM card, so write that number down before you contact them by phone.
- Since your SIM isn’t working, you’ll need to use a different phone (or a VoIP service like Skype or Google Voice) to contact customer service.
- Some providers, including AT&T, allow you to get the PUK online. If you have AT&T, you can follow these steps to get your PUK:
- Enter the PUK when prompted. The PUK is typically 8-digits long. Be careful when entering this code if you are unable to enter the correct PUK after 10 attempts,
- Create a new PIN. Even if you want to disable the PIN, you’ll need to create a new one before you can disable SIM locking. This time, write down your PIN so you have it in case you lose it.
- Disable SIM locking (optional). If you don’t want to use a SIM PIN in the future, here’s how you can disable SIM lock:
- iPhone: In the Settings app, tap Cellular, select SIM PIN, and then toggle off the switch. You will need to enter your new SIM PIN once to verify that you’re turning it off.
- Android: In the Settings app, tap Biometrics and security (or Security & lock screen, or similar), select Advanced or Other security settings, tap SIM card lock or Change SIM PIN, then then toggle off the switch.
