The customer service has sent me a PUK code twice that doesn't work. They don't seem to know what a NUC code is. Please help.</P> Wed, 29 Nov 2023 11:23:56 GMT https://community.o2.co.uk/t5/Pay-Monthly/Network-unlock-code/m-p/1672444#M267477 Fedupwith021 2023-11-29T11:23:56Z https://community.o2.co.uk/t5/Pay-Monthly/Network-unlock-code/m-p/1672447#M267479 <P><a href="https://community.o2.co.uk/t5/user/viewprofilepage/user-id/5389782">@Fedupwith021</a>&nbsp;</P><P>Guide here <LI-PRODUCT title="Guide: Unlocking an O2 phone to use a different SIM card" id="Guide003"></LI-PRODUCT>&nbsp;</P> Wed, 29 Nov 2023 11:29:26 GMT https://community.o2.co.uk/t5/Pay-Monthly/Network-unlock-code/m-p/1672447#M267479 MI5 2023-11-29T11:29:26Z
