Bring your number to Three

Are you bringing your number to a business SIM?

Only the main business account holder can request to bring their number to Three. By submitting this form you’re confirming that you’re the authorised account owner.

If you’re bringing more than one number to Three for your business accounts, you need to enter the details individually. If you have more than 25 numbers to transfer, give us a call on 0800 033 8033 to complete your switch.

Please make sure your SIM has been fully activated before completing this form - we recommend leaving 24 hours after activating your account before completing this form.
