Re: Keeping the phone after contract is done If you make all 24 payments then the phone is yours to keep.
When your O2 contract is coming to an end, the network operator will get in touch with you via text or email. If you happen to be out of contract with O2 already, it will send you an annual reminder that you're still paying for an old tariff.
O2 end of contract tariff options If you happen to be out of contract with O2 already, it will send you an annual reminder that you're still paying for an old tariff. In these notifications, O2 will offer you a selection of new plans that you could move onto once your fixed-term is finished.
Contact the business and say you want to cancel the contract because you're still in the cooling-off period. You'll probably need to give them details such as your account reference number - check any documents or emails you have from the company.
Almost all providers require 30 days' notice if you wish to leave.
The best way to cancel your account at the end of contract is by a PAC or STAC code. If you want to keep the number on an alternative network, text for a PAC and submit the PAC to the network. If you don't want to keep the number get a STAC and submit the code to any other network and the contract will end.
You usually cannot cancel a contract, but there are times when you can. You can cancel some contracts within certain time limits. Some contracts must tell you about your right to cancel, how to cancel them, and where to send the cancellation notice.
It's true that 30 days notice is needed when cancelling the contract, even if the contract has ended. This is only applicable to a standard cancellation through, and if you're planning on using a PAC or a STAC, the account will only be billed up until the point the new network completes processing of the PAC/STAC.
