Porting your mobile number from O2 to Plusnet Mobile

Leaving O2

How to switch from O2 & take your mobile number to Plusnet Mobile

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.

  • O2 will provide your Porting Authorisation Code (PAC) either over the telephone, by SMS text message or via email.
  • A PAC code 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 account will remain active until your number has been ported over to the new network. After the transfer is complete, your O2 account will be automatically closed.
  • O2 must issue you with a PAC number within 2 working days of your request, or a reason for why it cannot be issued, in accordance with Ofcom's "General Conditions of Entitlement". http://ofcom.org.uk

Many of the top mobile phone deals are available exclusively online, directly from the network providers listed here. So once you have received your Port Authorization Code from O2, get the best Plusnet Mobile offer suited to you.

Finally, provide your PAC code to your new Plusnet Mobile mobile network operator 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 contract before switching, otherwise you may lose your existing phone number and be unable to port it over. Once you provide your new network provider with your PAC code, your old account will automatically be closed once the 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 before porting your number.

How to switch to Plusnet Mobile & bring your O2 number with you

The first step is to sign up with Plusnet Mobile to get your new SIM card.

Once you have done that, ensure you have the following information ready:

  • Your original 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 Plusnet Mobile sim card.
  • You may also need the new SIM card number found on the back.

Once you have your PAC code, you can then text the word PORT to 07507 307 996 free from your new Plusnet SIM. They'll then send you a text. Just reply to that SMS with the mobile number you want to keep along with your PAC code. Alternatively, you can provide the PAC code over the telephone by calling customer services on 500 from your Plusnet Mobile or 0800 079 1133 from any other phone.

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 Plusnet Mobile 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.
