Before you begin
There’s a couple of quick steps you need to follow before switching your number to Three.
1. First, activate your new Three SIM
To activate your new SIM, simply put it into your device and switch it on. Once you see signal bars, it’s been activated. You might need to switch off Wi-Fi to see the signal bars.
2. Next, request a PAC from your previous provider
You can get a PAC for free by texting PAC to 65075 from the number that you want to keep. You’ll then get a PAC within 60 seconds, and it’ll be valid for 30 days.
If you have multiple numbers with your previous provider, you may need to contact them directly to get your PAC.

If you’ve got your PAC ready, and you’ve activated your SIM by inserting into the handset, then it’s time to switch. Just click the button below to continue.
If you’ve already given us your PAC and there's an issue with your transfer, or you want to change the transfer date, please see our support page.
