Thanks, your request has been submitted.

Your existing number will not be transferred to your Three SIM. We’ll send a text to that number to confirm this.

What's next

Now you’ve sorted out your number switch, you can carry on using your Three SIM as normal. Your number will switch within 24 hours of your chosen date, and from then you’ll be able to use it with your Three SIM. If you’ve delayed your switch date, just remember that you’ll be using the allocated Three number until the switch takes place.
