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).
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 ring 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.
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 from Lebara Mobile
Confirmed you’re out of contract? Okay, that’s all to the good. Now your job is to pick a SIM only deal from Lebara Mobile and sign up for it through uSwitch.
Once you’ve done that, Lebara will carry out some credit checks. After which point, you’ll be sent your SIM card in the post.
5) Contact Lebara Mobile to give them your PAC Code
The next item on your to-do list is to ring Lebara Mobile to give them your PAC Code.
The customer support team can be reached on 020 3059 0304 (standard network rates apply). Opening hours are 9am-5pm every day.
6) Insert the Lebara Mobile SIM in your phone
Next up, unlock the SIM tray on your phone with a pin-key and insert your Lebara Mobile SIM card.
Your number won’t be transferred straightaway. But you’ll be given a temporary number while the transfer is underway, so you’ll still be able to use your phone.
7) Wait for your number to be transferred to Lebara Mobile
Typically, number transfers are complete the next working day. But this may vary from network to network.
It’s also worth noting that if a weekend gets in the way, it could take a little longer.
