How to transfer your number from Sky Mobile to Three Mobile?

If you got a new phone as part of your contract, take the pin-key included in the box and unlock the handset's SIM tray. Then insert your Three SIM card.

If you went for a SIM-only deal instead, you can just put the Three SIM in your existing phone.

While the number transfer is taking place, you’ll be given a temporary phone number that you can use and on which people can contact you.
