Carphone Warehouse are just a retailer, your contract is with O2.
You need to cancel with O2 and give CPW your PAC when they process your new contract.
The number will changeover within 2 days (except weekends) and your O2 contract will be cancelled at the point of number change.
You will only be billed for the days past the 8th that you stay on O2.

No need to ring.
Just text for your PAC as per the info in guide.
You can get PAC now and give it to CPW when you order the new contract.
O2 will bill you up to the end of contract if done before 8th Aug or just bill you for a day or two after.
Best time to give PAC would be 5th August then you should be changed over by the 7th so getting maximum use from your O2 contract before leaving.
