Want to keep or change your number when switching to iD Mobile? You’ll need a PAC or STAC from your previous network. Watch our quick video guide to get started, or follow the detailed steps below:
Please note: If you gave us your PAC or STAC when you bought your plan, you're all set. There's no need to submit it again. Your switch will take place on the date you specified.
What is a PAC and STAC?
- A PAC (Porting Authorisation Code) is a unique 9-digit code that lets you transfer your number to a new network.
- A STAC (Service Termination Authorisation Code) is a unique 9-digit code that cancels your old number when switching to a new network.
How do I request a PAC or STAC?
In most cases, you can request a PAC or STAC from your old network via text, free of charge. Using your old SIM, text PAC to 65075 or STAC to 75075. You can also text INFO to 85075 to find out if you’re still in contract and if you’ll have to pay any exit fees. Your PAC or STAC will be sent immediately and is valid for 30 days. If your code expires before you use it, don't worry. You can just request a new one from your old network in the same way.
If you have more than one mobile number on your account, you’ll need to contact your old network directly.
What do I do once I’ve received my PAC or STAC?
Ready to make the switch? Awesome! Once you've got your PAC or STAC from your old network, giving it to us is simple. You can do it in one of three easy ways:
- During checkout - Give us your PAC when you choose your new plan or phone.
- In the iD Mobile app or my.idmobile.co.uk - Already have your iD Mobile SIM? The app is the quickest way to get your number switched over. Just follow these steps:
- Log in and tap the ‘Plan’ icon in the navigation bar.
- Scroll down and select ‘Switch to iD’.
- Tell us what you want to do. If you have a PAC, tap ‘I want to keep my old number’. If you have a STAC, tap ‘I don’t need my old number’
- Tap the button to confirm you have your PAC or STAC.
- On the next screen, enter the phone number you want to keep and your PAC or STAC.
- Tap the calendar icon to pick a date for your switch. Choose any working day that's convenient for you.
- Finally, tick the box to confirm you're happy to switch, and hit ‘Confirm’.
- On our website - You can also use our online switching form to submit your details at any time.
Please note: If you use the website form, you’ll need your transaction number. You can find this in your ‘Order Complete’ or ‘Welcome to iD’ email – it always starts with a 4. Need help finding your Transaction Number? Check out this Community article for more helpful information.
Once you submit your details, we’ll complete the switch on your chosen date.
When will my switch happen?
When you give us your PAC or STAC, we can switch or cancel your old number on the next working day by 10pm. Here are the exact timescales:
| Give us your PAC or STAC by | Switching Date |
|---|---|
| Monday before 5:30pm | Tuesday |
| Monday 5:30pm - Tuesday 5:30pm | Wednesday |
| Tuesday 5:30pm - Wednesday 5:30pm | Thursday |
| Wednesday 5:30pm - Thursday 5:30pm | Friday |
| Thursday 5:30pm - Friday 5:30pm | Monday |
| Friday 5:30pm - Monday 5:30pm | Tuesday |
Please note: During Bank Holidays, it can take a few extra days to switch your number to your iD Mobile plan.
What happens once my switch is complete?
On your switching day, you'll lose service on your old SIM at some point. If this happens, it's a good sign the switch is in progress.
Simply pop your new iD Mobile SIM into your phone (or activate your eSIM) and restart it occasionally. Once your switch is complete, we’ll send a confirmation text to your iD Mobile SIM.
Your old account should immediately disconnect. If this doesn’t happen, you’ll need to contact your old network. If you think your switch is delayed, check out the Community article below for more information:
What if iMessage, FaceTime, or Google Messages isn't working after my switch?
Sometimes, when you switch networks, the temporary number that came with your new SIM remains in your phone settings. This should normally update itself to the correct number after restarting your phone, but if it doesn’t, check out the Community articles below for more helpful information:
