If you are thinking of leaving O2 but want to keep your old number, you will need to obtain your O2 PAC code.

Follow the step by step instructions on how to get your O2 PAC code:

  • Call O2 free on 4445 (PAYG) or 150 (Contact) from an O2 phone or 0800 028 8151 and ask for ‘Retentions’.
  • O2 must supply you with your PAC code within 2 days. On receiving the PAC code it will be active for 30 days.
  • In the meantime, you should order a new mobile phone and select a package from your new network provider.
  • When ordering your new mobile phone online, you should insert the PAC code that O2 provided you into the relevant space on the website when placing your order. Alternatively, once you have received your PAC Code you can call your new network provider and enter the code over the phone.

That’s it! You will get a new temporary number until your old number is transferred over. (This could take up to 3 days).
