A PUK (Personal Unblocking Key) code is an 8-digit code used to unlock a SIM card that has been blocked after too many incorrect PIN attempts. If you enter your EE SIM PIN incorrectly three times in a row, your SIM will become blocked and you will see a message asking for your PUK code. Entering the wrong PUK code ten times will permanently destroy the SIM.

Unlike the PIN (3 attempts), you get 10 PUK attempts total across all time. Entering the wrong PUK 10 times permanently destroys the SIM card — it cannot be unblocked and a replacement must be ordered. Only enter the PUK once you have confirmed the correct code from your online account, SIM packaging, or network customer service.

Quick checks before resetting EE APN settings

Your EE PUK code can be found in several ways without having to call customer service:

1. EE account online: Log in to your EE account at the EE APN hub. Go to your SIM or account details section — the PUK code is usually listed alongside your SIM information.

2. EE app: Open the EE app and go to your account or SIM settings. Your PUK code should be visible in the SIM details section.

3. Original SIM packaging: The PUK code is printed on the credit-card-sized card your SIM came inside. Check any original packaging you may have kept.

4. Call EE customer service: If none of the above options work, call EE and ask for your PUK code. You will need to verify your identity. See the EE APN hub for the correct number.

Step-by-step EE data fix on Android and iPhone

When your phone displays SIM card locked — enter PUK code, type the 8-digit PUK code on the unlock screen. You will then be asked to set a new 4-digit PIN of your choice. Enter the new PIN twice to confirm. Your SIM will immediately unlock and reconnect to the EE network.

Escalating persistent EE data issues to support

You can disable the SIM PIN entirely if you prefer — go to Settings → Security → SIM Card Lock and toggle off Lock SIM Card. Alternatively, change your PIN to something more memorable via the same menu. A SIM without a PIN is less secure but eliminates the risk of accidentally locking it.

What if I enter the PUK code wrong?

You have ten attempts to enter the correct PUK code. After ten incorrect attempts, the SIM is permanently blocked and cannot be recovered. You will need to order a free replacement SIM from EE — your phone number and account will transfer automatically to the new SIM.
