Get iD Mobile PAC code to keep number & switch to VOXI network

Keep my iD Mobile number

How do I get a PAC code from iD Mobile & transfer my number to VOXI?

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.

If you wish to use the 'text-to-switch' service, simply send the SMS text PAC to 65075 free from your iD Mobile SIM to get your iD Mobile PAC code by text message and begin the porting process.
Alternatively, you can text STAC to 75075 if you want to switch and get a new VOXI number instead of keeping and transferring your iD Mobile number.

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

While you wait to get your PAC code from iD Mobile, find the best VOXI online offer for you. Many of these exclusive mobile phone & SIM only deals are only available online, directly from the network providers listed here.

Got your iD Mobile PAC code?

Provide your PAC code from iD Mobile to VOXI who will then be able to port your existing iD Mobile number. 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 current phone number and be unable to port it over. Once you give VOXI your iD Mobile PAC code, your old iD Mobile billing account will be closed automatically when your mobile phone number is successfully ported over.

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

Transfer my number to VOXI

How to switch to VOXI and keep my iD Mobile number?

First get your VOXI deal and activate your new SIM card.

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

  • Your old iD Mobile mobile phone number that you want to keep.
  • The iD Mobile PAC (Porting Authorization Code) from your previous network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new VOXI SIM card activation.
  • You may also need the new VOXI SIM card serial number found on the back as an additional security check.

With your PAC code and mobile phone number to hand, contact the VOXI support team by dialing 191 from your new VOXI sim, or call 03333 040 191 from any other phone.

If you are switching from Vodafone or Talkmobile, you do not need a PAC code as they run on the same network. Just let them know that you want to keep your mobile number when switching to VOXI.

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 VOXI signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your old phone number in your new mobile network provider.
