A PUK — Personal Unblocking Key — is the 8-digit code EE uses to unlock a SIM that's 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.
Getting your PUK code via customer service — EE PUK Code Free
There are a few ways to dig up an EE PUK code without ever picking up the phone to customer service:
1. The EE account portal often has it — log in and check SIM or account details for the PUK.
2. The EE app lists it too: account settings, then SIM details.
3. Check the original SIM card mount — EE prints the PUK right on the credit-card-sized holder, if you kept it.
4. Call EE support if all else fails — the PUK is given out after verifying identity, with the number on the EE hub.

What to do if your PUK code fails (EE PUK Code Free)
Via Settings → Security → SIM Card Lock, the PIN can be disabled completely or swapped for an easier one — a trade-off against security, but no accidental lockouts.
Entering the wrong PUK code (EE PUK Code Free)
Ten tries is the limit for entering the right PUK — get it wrong ten times and the EE 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.

Source the PUK from EE's account or the SIM holder rather than guessing
