Get BT Mobile PAC code to keep number & switch to iD Mobile network
Keep my BT Mobile number
How do I get a PAC code from BT Mobile & transfer my number to iD Mobile?
Contact BT Mobile to request your your PAC (Port Authorization Code) by dialing 150 from your BT Mobile or 0800 800 150 from another phone or +44 179 359 6931 from abroad.
If you wish to use the 'text-to-switch' service, simply send the SMS text
PAC to 65075
free from your BT Mobile SIM to get your BT 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 iD Mobile
number instead of keeping and transferring your BT Mobile number.
- BT 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 BT 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 BT Mobile account will remain active until your number has been ported over to your new iD Mobile network. After the transfer is complete, your old BT Mobile account will be automatically closed.
While you wait to get your PAC code from BT Mobile, find the best iD Mobile 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 BT Mobile PAC code?
Provide your PAC code from BT Mobile to iD Mobile who will then be able to port your existing BT 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 iD Mobile your BT Mobile PAC code, your old BT 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 iD Mobile
How to switch to iD Mobile and keep my BT Mobile number?
First get your iD Mobile 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 BT Mobile mobile phone number that you want to keep.
- The BT 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 iD Mobile SIM card activation.
- You may also need the new iD Mobile SIM card serial number found on the back as an additional security check.
With your PAC code from your previous network provider, log into your iD Mobile account and select My Services then click Keep My Number to enter your PAC code. From there you can select the Port Date and the mobile number you would like to keep.
Alternatively, contact customer services by calling 7777 free from your iD Mobile phone or 0333 003 7777 from any other telephone to provide those details.
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 iD Mobile 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.
