How to transfer your mobile phone number
To transfer your mobile number, you'll need to request a Porting Authorisation Code (PAC) from your current network. You can request this by texting your current network. Simply text 'PAC' for free to 65075 and you'll be sent your 'porting authorisation code' (PAC) immediately. To get a new number, text 'STAC' to 75075.
Once you have your PAC code, give it to your new network, and it will let your current network know you're looking to leave. The process usually takes one to three working days, although it can take longer in some cases.
If you're still in contract, you could be charged early termination fees for leaving - check how much you'd be charged by sending a text with the word 'INFO' to 85075.
Remember, your PAC code is only valid for 30 days. If you don't use it within this time, it will expire, and you'll need to request a new one.
It's a different process if you're swapping within the same provider.
If you're switching to a new tariff on the same network, for example, if you're on pay-as-you-go and upgrading to a contract, you shouldn't need to carry out this process - just call your mobile provider's customer service helpline and they should be able to sort it.
It's important to remember that the Sim-only deals listed in our tool are mostly for newbies of that provider. If you apply for a deal that's with your current provider and attempt to switch your current number to it, it'll likely be rejected by your network.
