General advice here...
Before we can transfer your number, we'll need your PAC code. This is made up of three letters and six numbers. You can get this from your current provider and it will be valid for 30 days.
You can give us your PAC code when you order your new O2 connection or at any time afterwards. Once you’ve given us your PAC code you’ll switch to our network within one working day (Monday-Friday, 9am-5pm, excluding bank holidays). If we receive your code after 5pm, you’ll switch within two working days. If you provide your PAC code at the weekend, you’ll switch on the following Tuesday.
Keep rebooting your phone.
