Unlock SIM card
To unlock your SIM card, enter the PIN you received with your SIM card. If you are using an eSIM, your PIN is usually provided digitally during the activation process rather than on a physical card. If you’ve lost your PIN or aren’t sure of the numbers, it’s best to find the code or contact your carrier rather than guessing. You only have a limited number of attempts; after that, you’ll need a PUK code to unlock the SIM card. We explain more about how this works below.
Unlock your SIM card with a PIN
You use a four-digit PIN (Personal Identification Number) to unlock your SIM card. For a physical SIM, you can usually find this code on the plastic card holder it came in. For an eSIM, the default PIN is often included in the confirmation email from your carrier or within the digital “eSIM profile” instructions provided when you scanned your QR code.
If you’ve forgotten the code and no longer have the packaging, you can often find this information by logging into your online account on your carrier’s website or mobile app. If you can’t find the right section or feel unsure, you should contact your carrier’s customer support directly for assistance.
Please note! If you have previously changed your PIN to a personalized one, you must use that code. In this case, the original code in your online account will no longer work.
It’s important to remember that you only have a limited number of tries to enter the correct PIN. With most Canadian carriers, you have a maximum of three attempts, though some may allow more. Always check with your carrier, as you should never try to guess your code.
If you enter the wrong PIN too many times, your SIM card will be locked. You will then need a PUK code to unlock it.
How do you use a PUK code?
The PUK code (Personal Unlocking Key) consists of eight digits. It is used to unlock your SIM card if you’ve entered the wrong PIN too many times. You have ten attempts to enter the correct PUK code.
After the tenth failed attempt, your SIM card will be permanently disabled, and you will need to order a new one. Make sure you have the correct PUK code and enter it carefully to avoid using up your attempts.
How do you get your PUK code?
Just like the PIN, the PUK code is usually printed on the plastic card holder that your SIM card was attached to. If you no longer have that or haven’t saved the code elsewhere, you will need to contact your carrier directly.
Most Canadian carriers also allow you to view your PUK code within your self-serve account via their website or app, though the layout may vary between providers.
If you have an eSIM, your PUK code is almost exclusively found within your online account or by contacting customer support, as there is no physical packaging to refer to. It is highly recommended to log into your carrier’s app and take a screenshot or note of your PUK code as soon as you activate your eSIM, just in case you lose internet access while the SIM is locked
Can you disable the SIM card PIN on your phone?
Yes, you can disable the SIM card PIN directly in your phone’s settings. Below is a guide for both iPhone and Android. Please note that these steps are general examples; menu options may vary slightly depending on your specific model and software version, especially on Android devices.
Turn off the PIN on iPhone
- Open Settings > Cellular > SIM PIN.
- If you have an iPhone with dual SIM or eSIM, go to Settings > Cellular, tap the specific number you want to manage, and then select SIM PIN.
- Toggle SIM PIN to the “Off” position.
- Enter your PIN if prompted. If you haven’t changed it, use the default PIN that came with your SIM card.
- Tap Done.
Turn off the PIN on Android
- Open Settings.
- Tap on Security & Privacy > More Security Settings.
- Select SIM Card Lock. (On some models, you may need to tap on the specific eSIM/SIM provider first).
- Toggle the Lock SIM card switch to the Off position.
- Enter your PIN to confirm.
Don’t confuse a SIM PIN with a carrier lock
It’s easy to mix them up, but they are two different things. In Canada, all phones sold after December 1, 2017, are required by the CRTC to be network-unlocked, meaning you are free to switch to any provider at any time.
This guide specifically covers the SIM PIN, which is a personal security feature for your SIM card or eSIM profile – not a restriction on which carrier you can use.
