1) Check you’re eligible to switch from Three
In the event that you’re out of contract, you’re free to switch whenever you like for no charge.
To find out your contract end date, you can:
Open up the Three app on your phone. Then click the ‘Plan’ icon at the bottom and scroll to the foot of the page, where you’ll find the date you’re free to leave.
Don’t have Three’s mobile app? No problem. You can also check your contract end date by logging into your Three account on Three’s site.
Prefer to call? You can get in touch with Three's customer support team on 333 from your Three phone. Or on 0333 338 1001 from any other phone (standard network charges apply).
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact Three to cancel your contract and get your PAC code
Okay. Now we’re really moving. With your new phone or SIM card winging its way to you, the next thing you need to do is contact Three and tell them you’d like to leave. At this point, you’ll be given a contract end date.
You can contact Three's customer support team by calling 333 from a Three phone. Or on 0333 338 1001 from any other phone.
Or, thanks to Text to Switch, you can just text PAC to 65075. You don't even need to make a phone call.
While you’re on the phone to Three, you also need to ask for a PAC Code. This is a short, alphanumeric code that you’ll need to transfer your phone number to the network you’re joining.
Three is bound by law to provide you with your code within two hours of your request. Once you’ve got the code, it’s a very good idea to make a note of it.
Your PAC code expires after 30 days. So if you haven’t used it within this timeframe, you’ll have to contact Three to get another one.
3) Early upgrades
Three does not offer a mid-contract early upgrade scheme that’s comparable to O2 Refresh or Tesco Mobile’s Anytime Upgrade.
However, customers on Three’s phone and contract plans are offered an upgrade with 30 days remaining on their contract.
4) Find and buy a SIM-only deal from Plusnet Mobile
Free as a bird? Or got an impending date when you’ll be ready to leave? Great. Now you need to select a SIM only deal from Plusnet Mobile and sign up through Uswitch.
Once you’ve passed Plusnet Mobile’s credit checks, you’ll receive your SIM in the post.
5) Contact Plusnet Mobile to give them your PAC Code
Your only real job now is to get in touch with Plusnet Mobile and give them your PAC code.
You can get in touch on 0800 079 1133 (standard network charges apply).
6) Unbox and insert your Plusnet Mobile SIM
Got your phone to hand? Okay, open up the SIM tray using a pin and insert your Plusnet Mobile SIM card.
Your number won’t be transferred straightaway. But you’ll be given a temporary number to use while the number transfer is taking place. So you can still use your phone.
7) Wait for your number to be transferred to Plusnet Mobile
Plusnet aims to complete number transfers the next working day. However, that may depend on the time of day you make your transfer request.
The earlier you make your request, the more likely it is to happen the next day.
