Porting your mobile number from Tesco Mobile to 1pMobile

Leaving Tesco Mobile

How to switch from Tesco Mobile and transfer my number to 1pMobile

Call Tesco Customer Care on 4455 from your Tesco Mobile phone or alternatively 0345 301 4455 from another telephone, to request your PAC code.

You can also transfer your number from one Tesco Mobile SIM to another by texting SWAP to 23424 for free from your original SIM card.

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

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

While you wait for your Port Authorization Code from Tesco Mobile, get the best 1pMobile deal 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 Tesco Mobile?

Provide your PAC code from Tesco Mobile to 1pMobile online who will then be able to port your existing phone number from Tesco Mobile. 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 when 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 1pMobile and keep my Tesco Mobile number?

The first step is to choose your 1pMobile plan and receive 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 Tesco Mobile network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new 1pMobile SIM card.
  • You may also need the new SIM card number found on the back.

Log in to your 1pMobile account and activate your SIM if you haven't already.

You will be asked if you want to keep your number, and prompted to enter your Porting Authorisation Code (PAC).

You can then choose the day you would like to transfer your existing mobile phone number, providing at least two working days notice.

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 1pMobile 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.
