How to switch from O2 and transfer my number to The Phone Co-op

Ask for your Port Authorisation Code (PAC) from O2 customer services by contacting them, either from your 02 mobile phone on 4445 for Pay As You Go, or 202 for Pay Monthly contracts. Alternatively from a landline: dial 0344 8090222 for Pay As You Go customer Service or 0344 8090202 for Pay Monthly customer Service.

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your O2 SIM to request a PAC code by text message and begin the porting process.

  • O2 will provide your Porting Authorisation Code (PAC) either by SMS text message, via email, or over the phone if you contact them.
  • 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 O2 online account settings will remain active until your number has been ported over to the new network. After the transfer is complete, your account will be automatically closed.

While you wait for your Port Authorization Code from O2, get the best The Phone Co-op offer for you. Many of these exclusive mobile phone deals are only available online, directly from the network providers listed here.

Got your PAC code from O2?

Provide your PAC code from O2 to The Phone Co-op online who will then be able to port your existing phone number from O2. 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 existing phone number and be unable to port it over. Once you give your new network provider your PAC code, your old billing account will be closed automatically when your number is successfully ported over.

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

Joining The Phone Co-op

How to switch to The Phone Co-op and keep my O2 number?

First get your The Phone Co-op package and activate your new SIM card.

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

  • Your old O2 mobile phone number you want to keep.
  • The Porting Authorisation Code (PAC) from your previous O2 network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new The Phone Co-op SIM card activation.
  • You may also need the new The Phone Co-op SIM card serial number found on the back.

Contact The Phone Co-op on 01608 434 000 or fill out the customer services form form to provide your PAC (Port Authorisation Code) from your previous mobile network provider.

Please note that they ask for at least 5 working days notice before your PAC expires to transfer your number to them.

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 The Phone Co-op signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your existing phone number in your new mobile network provider.
