If you're moving your mobile service to O2 or another network, you might find that your phone is locked to Vodafone. If you're not sure, you can check by inserting a SIM card from any network other than Vodafone into your phone. If you see an error message such as:
SIM Card Not Accepted
Enter SP Code
Insert Correct SIM Card
Your phone is locked to Vodafone. You'll need to get your phone unlocked before you can use another network SIM card. The good news is, we can arrange this for you free of charge.
The IMEI (International Mobile Equipment Identity) is a 15 or 17-digit code, which is unique to your device. You should be able to find it:
You'll need to know the model of iPhone you have before you contact us. We'll need to know whether it's an iPhone 8, iPhone x, iPhone 11 etc.
There are a couple of ways you can find the model of your iPhone if you're unsure:
Tap Settings in the main iPhone menu and then and tap on your iCloud profile at the top of the menu. You'll see your model name listed a little way down the page as 'This iPhone XX'.
Connect your iPhone to iTunes on your computer. Once you've selected your iPhone, you'll see your model name at the top of the screen.
Tap Settings from the main menu > About.
Your model name and number will be displayed in the Phone Information Section.
Type in *#0000# on your phone's keypad. The display shows your phone's model.
Once we've let you know that your unlock request has been processed, here's how to unlock your phone:
iPhones are unlocked Over the Air. Simply insert your new SIM card and start using your new service.
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.
