Get Virgin Mobile PAC code to keep number & switch to O2 network

Keep my Virgin Mobile number

How to get a PAC code from Virgin Mobile & transfer my number to O2

Call Virgin Media on 789 from a Virgin Mobile SIM or dial 0345 6000 789 from any other phone, and ask for your "Port Authorisation Code" or PAC number.

To use the text-to-switch service make sure to include your date of birth (as DD/MM/YYYY format) when texting PAC to 65075 e.g. PAC 19/07/1987

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your Virgin Mobile SIM to get your Virgin Mobile PAC code by text message and begin the porting process.

  • Virgin Mobile will provide your PAC code (Porting Authorisation Code) either by SMS text message, email, over the phone if you contact them directly, or through an online Virgin Mobile login.
  • A PAC number is valid for 30 days. If you don't use it within thirty days it will expire and you will need to request a new one.
  • Your Virgin Mobile account will remain active until your number has been ported over to your new O2 network. After the transfer is complete, your old Virgin Mobile account will be automatically closed.

While you wait to get your Virgin Mobile PAC code, find the best O2 online offer for you. Many of these exclusive mobile phone & SIM only deals are only available online, directly from the network providers listed here.

Got your Virgin Mobile PAC code?

Provide your PAC code from Virgin Mobile to O2 who will then be able to port your existing Virgin Mobile number. They will tell you what day the transfer is due to take place (usually within 48 hours).

Important: Do NOT cancel your SIM only or mobile contract before switching, otherwise you may lose your current phone number and be unable to port it over. Once you give O2 your Virgin Mobile PAC code, your old Virgin Mobile billing account will be closed automatically when your mobile phone number is successfully ported over.

Note: Topup credit on Pre-Pay / PAYG (Pay-As-You-Go) accounts cannot be transferred over and so any remaining credit balance or bundles will be lost after the switch is complete. If you have any top-up credit left, one good option is to donate your remaining balance to a charity via SMS text message before porting your number.

Transfer my number to O2

How to switch to O2 and keep my Virgin Mobile number?

First get your O2 deal and activate your new SIM card.

Once you have done that, get the following information ready for the step-by-step instructions:

  • Your old Virgin Mobile mobile phone number that you want to keep.
  • The Virgin Mobile PAC code (Porting Authorization Code) from your previous network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new O2 SIM card activation.
  • You may also need the new O2 SIM card serial number found on the back as an additional security check.

Contact O2 customer services with your PAC code and let them know you wish to transfer your old number to O2. You can reach them either from your 02 mobile phone on 4445 for Pay As You Go, or 202 for Pay Monthly contracts.

If you are calling from a landline: dial 0344 8090222 for Pay As You Go customer Service or 0344 8090202 for Pay Monthly customer Service.

Alternatively, you can fill in the online O2 form and they will contact you when the transfer is complete.

Note: You may lose network service for a short period on the day of transfer. If this happens, turn your phone off and on occasionally, until you see the O2 signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your old phone number in your new mobile network provider.
