You’ve got a new phone or SIM card but want to keep your old mobile number - that's not much to ask for, really, is it? Don’t worry, it’s a fairly simple process. Here’s everything you need to know about keeping your number when you change your contract or SIM card - even if you're joining a new network.

What do I need to keep my number?

You’ll need a PAC (Porting Authorisation Code – sometimes called a 'PAC code'). This is a number that lets you transfer your current number to your new SIM card. You need to get this from your current network.

Do I always need a PAC?

No, not always.

If you’re moving from one network to another, you’ll need a PAC.

If you’re staying with your current network, you’ll need a PAC if you’re upgrading from a Pay As You Go (PAYG) deal to a Pay Monthly (contract) one.

If you’re upgrading from one Pay Monthly contract to another - or upgrading from a PAYG phone to another - you don’t need a PAC. Your number will automatically be activated on your new SIM.

How do I get my PAC code?

Call your current network and ask for your PAC. It’s free to get your PAC, and your network has to give you one within two days, or tell you why they can’t.

You need to get your PAC before you disconnect your old SIM. If you don’t, you won’t be able to transfer your number.

What do I do with my PAC?

When you’re buying your new phone, tell the in-store colleague, or the staff member on the other end of the phone, that you want to keep your number. They'll normally ask for your PAC then, so if you have it already, that will make everything move quicker. Your PAC is valid for 30 days, so you have plenty of time to use it, but try to use your PAC as soon as possible.

Can I use my PAC after I've bought my new phone?

Yes, you can. Call up your network with your PAC code and they’ll be able to transfer your number to your new deal. Make sure you contact them before your SIM has been disconnected.

How long will it take to transfer my number?

Normally just two working days, but it can take a little longer in certain circumstances. If you give your PAC code to your network, the amount of time it takes to transfer your number can vary.

Does a new SIM card give me a new number?

Usually, yes. Popping in a new SIM card means you’ll get a shiny new mobile number too. But don’t worry, you don’t have to memorise a new one if you don’t want to! If you're switching to a new network but want to hang on to your current number (because who has time to update all their contacts?), all you need is a PAC code. That’s a Porting Authorisation Code – just text PAC to 65075 from your current phone, and your provider will send it to you. Give that code to your new provider when you sign up, and voilà – your number moves with you, like magic.

Can I keep my number if I lose my phone?

Yes, you absolutely can. The key thing to do is contact your network provider ASAP. They can block the lost SIM to stop anyone else from using your number, and then they’ll send you a replacement SIM card with the same number. Once you pop that new SIM into your new (or found!) phone, you're back in business with your original number. Crisis averted!

Can I transfer my number from SIM to eSIM?

Yes, you can. And it’s easier than you might think. eSIMs are the digital version of a traditional SIM card, and they’re super handy because there’s nothing to physically insert or remove. If you’re moving to a new network and want to use an eSIM, the PAC code process still applies – text PAC to 65075, give that code to your new provider, and they’ll set up your number on the eSIM. If you're staying with your current provider but just switching from a physical SIM to an eSIM, you usually won’t need a PAC – just get in touch with your network and they’ll guide you through activating the eSIM while keeping your number.
