⚠ 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.
Getting an unlock code from Vodafone — How to Unlock Vodafone Phone
Several self-service routes exist for finding a Vodafone PUK code:
1. Log into your Vodafone account online and check SIM or account details, where the PUK is normally shown.
2. The Vodafone app lists it too: account settings, then SIM details.
3. Check the original SIM holder — Vodafone prints the PUK on the credit-card-sized carrier.
4. Ring Vodafone support as a last resort — they provide the PUK after an identity check, with the number on the hub.
