A PUK or 'Personal Unlocking Key' is a security feature on most mobile devices that protects your SIM card data. A PUK code is required when a SIM Card PIN code has been entered incorrectly.You can get your PUK code:
Using your PC: via My Account
Using another phone: via a Call
Unlocking a SIM card with a PUK differs from 'Network Unlocking' which allows a mobile device to be used with other mobile networks.
If your IMEI number and device has been blocked due to a lost stolen / scenario please see this article instead for details.
If you don't know your PIN, just hold the line for these further options.
If you experience difficulty entering your PUK, consult your user manual or contact us.
