The PUK is an 8-digit Personal Unblocking Key that clears an EE SIM blocked by wrong PIN entries. Three bad PINs blocks it; ten bad PUKs destroys it.

⚠ Do NOT guess the PUK — 10 wrong attempts 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
EE offers several self-service routes to a PUK code:
1. Log into EE's account portal and look under SIM or account details for the PUK.
2. Check the EE app under account or SIM settings for the PUK.
3. The original SIM holder has the PUK printed on it, if it's still around.
4. Contact EE customer services as a final option; an identity check, then they'll read out the PUK.
