If you’re having problems using your Network Unlock Code (NUC), make sure you’re entering it correctly. Network Unlock Codes are case sensitive, so you’ll need to enter it exactly as it was given to you.
The NUC will work for only the specific device you gave us the details for. If you want to unlock a different device that's been used on TalkTalk Mobile, you’ll need to contact us.
You only get a limited number of attempts to type in your code. If you’ve entered it correctly but are still having problems, we recommend you contact us for support and to double check your NUC.
