Switch from O2 to Sky Mobile and keep your number using a PAC code

Ofcom’s policies have made it extremely quick and easy to switch and transfer your O2 number to Sky Mobile.

It’s completely free to transfer your number - you simply need to request a PAC code from O2 by sending a text message, which takes no more than 2 minutes to arrive. Once you’ve handed the PAC code to Sky Mobile, the switching process will take no more than 1 to 2 working days to complete.

If you want to join Sky Mobile and get a brand new phone number, without keeping your existing O2 number, the process is almost identical - the only difference being you will need to request a STAC code instead of a PAC code.

Joining Sky Mobile and transferring your number from O2 is a very easy process, and should take no more than 1 to 2 working days.

You simply need to request a free PAC code from your O2 number, and hand it to Sky Mobile.

You can hand your PAC code to Sky Mobile at the time of ordering a new Sky Mobile phone or Sky Mobile SIM, or you can do this after you’ve received your order. When you choose to do this is up to you - it doesn’t make a difference.

After you’ve handed your PAC code to Sky Mobile, your number will be transferred to Sky Mobile within 1 to 2 working days, and your account with O2 will automatically be closed.

1. Request a PAC code from O2

Requesting a PAC code from O2 is quick and free. The easiest way to do this is via text:

  1. Text: From your O2 number, text PAC to 65075 for free. You will receive a reply within 2 minutes, containing your PAC code
  2. Online: Login to O2, open the My O2 ▾ menu, click Manage your details, then under Thinking of leaving O2? click Request your code. You'll then be asked to perform a quick security check, before you can see your PAC code
  3. Phone: Call 202 from your O2 number or 0344 809 0202 from any other number.
    • Monday - Friday: 8am - 9pm
    • Saturday: 8am - 8pm
    • Sunday: 8am - 6pm
  4. Store: Locate your nearest O2 store and request to leave O2

You will have 30 days to hand your PAC code to Sky Mobile, after which it will expire and you will need to request another one from O2.

Note: If you wish to switch to Sky Mobile, but you want a brand new number without keeping your O2 number, you need to request a STAC code rather than a PAC code from O2. You can do this by texting STAC to 75075 instead.

2. Order a new phone or SIM from Sky Mobile

If you’re not given the opportunity to hand your PAC code to Sky Mobile at the time of ordering, don’t worry. Instead, you will receive a temporary number with your new Sky Mobile SIM.

Note: Apart from being slightly more convenient, it doesn’t make a difference whether you choose to hand your PAC code to Sky Mobile at the order checkout or after you’ve received your order.

3. Hand the PAC code to Sky Mobile
