How to move your phone number
Don’t feel like letting everyone you’ve ever met know you’ve got a new number? We don’t blame you. So, it’s a good thing that keeping your old phone number is both quick and easy – with PAC code.
Lots of us have had our phone number since, well, forever. So, the idea of switching to a new one seems like a whole lot of hassle, especially when you’re moving to another network.
But, good news, you won’t have to wave goodbye to those digits you’ve had for donkey’s years. Thanks to the UK’s Auto-Switch system, keeping the same number is super quick and super simple – here’s how.
Step 1: Text PAC to 65075
It’s free, works on all UK networks, and you’ll usually get a reply in seconds. PAC codes are valid for 30 days, so you’ll need to hand it to your new provider before it expires.
Step 2: Give your PAC to your new network
You'll be able to share your code when you sign up for your new SIM or contract.
Most networks let you enter it when you checkout, but if you’re already set up, customer service should be able to sort it out. Once you’ve passed it along, they’ll do all the tech-y bits to have your number transferred over.
Step 3: Complete the switch
Now just wait for the actual move to be happen – and don’t worry, this part’s usually pretty painless.
As a rule, if you send your PAC before 5pm, your number will transfer over the next working day (after 5pm it'll be 2 working days).
During the switch, your old SIM will eventually tap out and stop working. That’s your cue to swap in the new SIM, pop on the kettle, and you should have your trusty number back in no time at all.
Some important bits to remember
If you’re changing plans with the same network, your number won’t change.
You can’t move your number to the same network – that’s an upgrade, not a switch. And don’t worry, when you upgrade, you keep your number automatically.
Check you’re not tied into a contract
If you’re still in contract, you may have to pay an early termination fee. Even if you switch, you’re still responsible for any outstanding bills. Your old network will sort that out for you.
Don’t cancel your old SIM first
You don’t have to cancel your old provider yourself. The PAC transfer does this automatically, so you’re saved from an awkward phone call. Plus, cancelling early could cause you to lose the number permanently.
Back up your phone
Save contacts, photos, and messages before the switch, just in case. Some services (WhatsApp, banking apps) may need re‑verification.
And hey presto - new network, same trusty number. Quick, easy, and no need to start sending out mass texts explaining who you are.
- How do I keep my existing number if I move to AO mobile?
It’s a really simple process. You just need to ask your existing network provider for a PAC code by texting 67075. You’ll receive the PAC via text message and you’ll need to give it us when you order your SIM. If you already have your AO Mobile SIM and didn’t request a PAC code, you can get in touch so we can help you transfer over.
- How long does it take to transfer my number?
In most cases, it takes less than 1 working day. But, if it happens over a weekend or a bank holiday, it could take a little longer.
- Is there a time limit on keeping my number?
Yes there is. If you cancelled your contract with your previous provider without requesting a PAC then you have 1 month to request it. If you have already requested a PAC, it's valid for 30 days. If it expires, you can request a new one, but you'll need to provide it within 30 days to keep your number.
- My PAC has expired, what do I do?
PACs last 30 days. If yours has expired, simply request a new PAC in the same way by texting PAC to 65075. Remember: you only have 30 days after cancelling your contract with your previous provider to transfer your number over.
- When do I need a STAC code?
You need a STAC code when you want to switch mobile networks and get a new phone number while also closing your old account and number down in the process. STAC codes can be requested from your current provider by texting STAC to 75075 (this number can vary by network so check with your current provider). You then give the code to your new provider to start your new service and cancel your old one.
Your provider must send your STAC and any other info on potential charges within 60 seconds by text message or 2 working days if you requested online or over the phone. The code is valid for 30 days.
- What’s the difference between a PAC and STAC code?
A STAC code (Service Termination Authorisation Code): For closing your old mobile account and getting a new phone number.
A PAC code (Porting Authorisation Code): For Keeping your old number when switching to a new network.
- I'm not sure if I'm still in contract, how do I check?
Text INFO to 85075 to find out your contract status and any early-termination charges.
- What do I need to do on the day my number switches over?
Just keep using your existing SIM as normal until it shows as No Service on your phone’s screen. Then insert or activate your new SIM card. A brief loss of service is normal during the switch and you may just need to restart your phone.
- What do I do if I have an issue transferring my number?
Delays are usually due to mismatched account info (name, account number, date of birth), a pending balance, or missing info as part of the request.
Here’s what to try:
- Contact us to check the status and any error codes.
- Confirm details with your old network exactly match their records.
- Restart your phone after we confirm the port has completed.
- I'm receiving calls but not messages, what can I do?
Messages can sometimes lag behind calls after switching over.
Try:
- Turning iMessage/RCS off, waiting 30 seconds, then on again.
- Restarting your phone and checking you’re on the AO Mobile network.
- Do I need to give notice to my old provider?
No you don’t. Once you give us your PAC or STAC code, we’ll handle the switch and cancel your old service. Remember: You may still receive a final bill or any early termination charges if you’re leaving your contract early.
