Please complete the details below.

    The number that comes with your new Three SIM.

    Your existing phone number

    You can get this from your old network - not Three. It comes in 123456ABC format and uses capital letters.

    The earliest available date is automatically selected above, but you can pick any working day within the next 30 days if you prefer. Bear in mind that Bank Holidays can’t be chosen, and some other dates may be unavailable.

    Switching your services
    Before we can switch your services to Three, we need to confirm you understand what this means.

    Your existing provider will have sent you important information about the impact the switch will have on your services with them. This will cover any charges you’ll need to pay or refunds you’re due. If you use your STAC to switch your services to Three and later change your mind about bringing your number to Three, you will need to contact your previous service provider to see if this is possible.

    Our support pages have more information about our switching process.  This includes information about your right to compensation if there’s a delay. These details are also in the pre-sales contract information. 

    We’ll keep a record of this consent, in line with regulations.
