1) Check you’re eligible to switch from iD Mobile
If you’re out of contract with iD Mobile, you’re free to switch network whenever you like and it won’t cost you anything.
In the event that you’re not sure of your contract status, customer support a call on 7777 from your iD Mobile phone. Or you can ring 0333 003 7777 from a landline or any other mobile phone (charges may vary).
Opening hours are 8am-8pm every day of the week.
Don’t want to speak to anyone? You can also find out your contract end date by logging into to your iD Mobile account. Or you can open up the iD Mobile app on your phone and find it there.
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact iD Mobile to cancel and get your PAC Code
Next up, you need to get in touch with iD Mobile. To do this, just text PAC to 65075 to get your 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. You don't even need to make a phone call.
If you'd prefer to speak to somebody, just ring iD Mobile on one of the numbers in step 1 and tell them you want to leave. While you’re on the phone to them, you also need to ask for your PAC Code.
It’s a legal requirement that networks provide you with a PAC Code within two hours of your request.
The important thing to note, though, is that your PAC Code will expire if it’s not used within 30 days.
If, for whatever reason, you don’t get around to using it in that timeframe you’ll need to contact iD Mobile again to ask for 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.
