Porting your mobile number from iD Mobile to Tesco Mobile

Leaving iD Mobile

How to switch from iD Mobile & take your mobile number to Tesco Mobile

Contact iD Mobile customer services by calling 7777 free from your iD Mobile phone or 0333 003 7777 from any other telephone to request your PAC code. Make sure you ask for the PAC before the end of any contract agreement.

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

Once you have received your Port Authorization Code from iD Mobile, look for the best Tesco Mobile offer that is suited to you. Many of the best mobile phone deals are available exclusively online, directly from the network providers listed here.

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 iD 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 might not be able to port over your number. Once you provide your new network provider with your PAC code, your old account will automatically be cancelled when the number is migrated over.

Note: Credit on a PAYG (Pay-As-You-Go / Pre-Pay) account cannot be transferred and any remaining credit will be lost after the switch over.

Joining Tesco Mobile

How to switch to Tesco Mobile & bring your iD Mobile number with you

The first step, if you haven't already, is to sign up with Tesco Mobile.

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

  • Your original mobile phone number you want to keep.
  • The Port Authorization Code (PAC) from your previous iD 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 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.
