Do i need to upgrade or can i buy a new contract?

[Ieuster]

My contract is up soon and i want to stay with O2 but there's nothing on the site under £30, so i went to affordablemobiles.co.uk and saw that if i buy a new contract it's a lot cheaper than if i look on their upgrade section. do i have to get a new contract via upgrade or can i buy one from scratch?

If you upgrade you will be able to keep your current number. If you set up a new contract, that will come with it's own sim.

You have to do what's best for you.
