Swap your number from one SIM to another
Got a new SIM? Fill in the form on this page and we'll swap your number to your new SIM. It normally takes about 30 minutes for the number to be swapped, but sometimes it can take up to 24 hours.
Looking for your SIM number?
The SIM number is printed on the new SIM card itself. You can also find it through your phone's menu (unfortunately, this isn't available on Android phones).
Enter the number of your SIM card in the form on this page. Use the prefix 89441 followed by the 15 digits on your SIM – none of the letters are needed.
You’ll need to swap your SIM if:
- You've changed or upgraded your phone and it needs a different size SIM (check our handy guide to see what SIM you need)
- Your phone’s lost or stolen
- Your SIM is damaged
If you’re joining us from another network or switching from Pay as you go to Pay monthly, you can keep your current number by transferring it over.
If you're a large business or corporate customer, please contact your account manager.
