  1. 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. 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. 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. 4) Find and buy a deal on iD Mobile

    Found a deal you like the look of on iD Mobile? Okay, now just sign up for it through uSwitch.

    iD Mobile will then conduct some credit checks. After which point, you’ll receive your phone in the post.

  5. 5) Contact iD Mobile to give them your PAC Code

    Almost there now. You’ll now need to get in touch with iD Mobile and tell them your PAC Code.

    Ring them on 0345 6000 789 (standard network charges apply). Opening hours are 8am-8pm every day.

  6. 6) Insert your iD Mobile SIM

    Signed up for a new phone from iD Mobile? Okay, using the pin-key in the box it's time to open the SIM tray and insert your iD Mobile SIM.

    Opted for an iD Mobile SIM only deal? You just need to pop the SIM in your existing phone.

    Your phone number won’t be transferred instantly. But you’ll be given a temporary number to use in the interim, so you’ll still be able to use your phone.

  7. 7) Wait for your number to be transferred

    The time it takes to transfer a number varies between networks. But in general, your transfer should be complete the next day. Unless a weekend or Bank Holiday gets in the way, in which case it may take a little longer.

    But once it's done, you're good to go.
