What's next?
Now you’ve commited to a new number, you can carry on using your Three SIM as normal. We'll let your previous supplier know you're leaving and they'll close your account. Your previous number will be deactivated within 24 hours of your chosen date.
Remember, if you've delayed your deactivation until a certain date, the previous number will stay active until then.
