Porting your mobile number from Orange to Tesco Mobile

Leaving Orange

How to switch from Orange & transfer your mobile number to Tesco Mobile

Contact Orange to request your "Port Authorisation Code" (PAC) at the same time you give your notice of leaving. The Orange customer support line for Pay Monthly customers is 07973 100 150 (or 150 from your mobile), and for Pay As You Go customers dial 07973 100 450 (or 450 from your mobile). Orange will then send out your PAC code by post within 2 working days.

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

  • Orange will provide your Porting Authorisation Code (PAC) either over the phone, 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 Orange account will remain active until your number has been ported over to the new network. After the transfer is complete, your Orange account will be automatically closed.

Many of the exclusive mobile phone deals are only available online, directly from the network providers listed here. While you wait for your Port Authorization Code from Orange, get the best Tesco Mobile offer tailored to you.

Finally, provide your PAC code to your new Tesco Mobile mobile network operator who will then be able to port your existing phone number from Orange. 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 be clsoed automatically 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.

Joining Tesco Mobile

How to switch to Tesco Mobile & keep your Orange mobile number

The first step is to sign up with Tesco 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 Orange network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new Tesco Mobile sim card.
  • You may also need the new SIM card number found on the back.

Contact Tesco Customer Care by dialing 4455 from your Tesco Mobile phone or call them on 0345 301 4455 from another telephone. Let customer services know that you would like to transfer your old number to your new TescoMobile account and provide them with the PAC number from your old network provider.

Alternatively, you can text PORT to 23424 free from the Tesco Mobile number you want to replace.

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 Tesco 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.

About Orange

Orange UK was a mobile network operator and a former internet service provider in the United Kingdom, launched in 1993. In 2000, it was purchased by France Télécom (now Orange S.A.), which then adopted the Orange brand for all its other mobile communications activities.

Orange UK has since merged with Deutsche Telekom's T-Mobile UK to form a joint venture, EE. EE continued to operate the Orange brand until February 2015, when new connections and upgrades on Orange tariffs were withdrawn. Existing Orange customers who wish to upgrade must switch to an EE tariff when their contract term ends, or can choose to remain on their existing Orange tariff without renewing.
