1) Check you're eligible to switch from EE
If you're out of contract with EE, you can switch for no charge whenever you like.
Not sure if you're out of contract? To find out, you can call 150 from your EE phone to speak to customer support. Or on 07953 966 250 from any other phone (standard network charges apply).
Opening hours are 8am-8pm Monday-Friday. 8am-6pm at weekends.
Don't fancy phoning? Log in to your EE account online instead.
Keeping your old phone and signing up for a new SIM-only deal with a new network? Okay, that means there’s a chance you may need to get your phone unlocked.
The good news is that this is very simple. Just head to EE’s site where you’ll find a form to fill in to unlock your smartphone.
Once that’s done, they’ll provide you with a personal unlocking key (PUK) that you can use to unlock your handset.
2) Contact EE to cancel your contract and get your PAC code
Once you’ve found a new deal and signed up, your next task is to ring EE and tell them you want to leave. They’ll give you a contract end date that you should make a note of.
While you’re on the phone to them, you also need to ask for a PAC Code. It’s this short alphanumeric code that will enable you to transfer your existing phone number to the network you want to join. EE is bound by law to provide a PAC Code within two hours of you asking for it.
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.
