1) Check you’re eligible to switch from Virgin Mobile
If you’re out of contract with Virgin Mobile, you can switch at any time and it won’t cost you anything.
It’s very easy to lose track of your contract end date, though. If you’re not sure of yours, you can find out by calling Virgin Mobile’s customer support team on 789 from your Virgin Mobile phone.
Alternatively, you can reach them on 0345 6000 789 from any other phone (standard network charges apply).
The support centre’s opening hours are 8am-12pm every day.
If you prefer not to call, you can find out your end date by logging in to your account.
Or you can find it by opening up the Virgin Mobile app on your phone.
2) Contact Virgin Mobile to cancel and get a PAC Code
No-one likes goodbyes. But you now need to get in touch with Virgin Mobile to inform them you’re leaving. You can reach them on the same contact numbers listed in step 1.
While you’re on the phone, ask the team for a PAC Code too. This is a sequence of numbers and letters that you’re going to need to transfer your existing number to the network you’d like to join.
Regulations stipulate that all networks must provide you with your PAC Code within two hours of your request. When you’ve got the code it’s smart to make a note of it. Just to be safe.
What you really need to be aware of, though, is that PAC Codes expire after 30 days. So if you don’t use yours within that timeframe, you’ll need to get in touch with Virgin Media again to request a new one.
3) Find and buy a new deal from O2
Your next task is to choose and sign up for a new deal contract from O2. Once you’ve passed O2's credit checks, you’ll receive your phone or SIM card in the post.
4) Contact O2 to give them your PAC code
Now you’ll just to ring O2 to give them your PAC. You can get in touch with O2's customer support team on 034 4809 0202 from a landline (standard network rates apply).
5) Insert your new SIM card from O2
If you got a new phone, use your pin-key to unlock the handset's SIM tray. Then insert your O2 SIM.
If you went for a SIM-only deal, you can just put the O2 SIM in your existing phone.
While your number is being transferred, you'll be supplied with a temporary number to use. So you can still make and take calls and do whatever you'd normally do on your phone.
6) Wait for your number to be transferred from O2
The transfer should be complete the next working day. But this varies depending on the network you're joining.
The transfer could also take a little bit longer if a weekend or Bank Holiday gets in the way.
