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 deal from Sky Mobile
Cleared to switch? Smashing news. Your next task is to select a deal from Sky Mobile and sign up for it through uSwitch.
Sky Mobile will then carry out some credit checks, after which point you’ll be sent your phone or SIM in the post.
5) Contact Sky Mobile to give them your PAC Code
Got your PAC Code to hand? Okay, your next task is to ring Sky Mobile and give it to them.
The number to call is 03300 412 524 (standard network charges apply). The Sky Mobile call centre is open 8.30am-11pm every day.
6) Insert your Sky Mobile SIM
It’s zero hour. If you got a new phone, it's time to take your pin-key and unlock the handset's SIM tray. Then insert your Sky Mobile SIM.
If you bought a SIM only deal, you can just put the Sky Mobile SIM in your existing phone.
Your number won’t be transferred straightaway. But while the transfer is underway, you’ll be given a temporary number. So you’ll still be able to use your phone.
7) Wait for your number to be transferred to Sky Mobile
Number transfers are usually complete the next working day. But the time it takes depends on the network and whether weekends get in the way. In which case it may take a little bit longer.
Once it's done, you're good to go.
