Keeping Your Phone Number
If you’re switching to Three so you can take advantage of their 6 months half price offer, it’s easy to keep your current UK phone number.
Start by asking your current mobile network to give you a PAC Code. You can get one through your mobile network’s website or app, or by texting PAC to 65075. Once you have it, order your new phone or SIM card from Three’s website.
When your new phone or SIM card arrives, fill out this form on Three’s website. After you’ve submitted your PAC Code in the form, Three will schedule the transfer of your phone number (normally for the next working day). In the meantime, you’ll continue receiving a service from your old network.
