I currently have an o2 account which is just approaching the 11 month of a 12 month contract. Am joining t-mobile to go onto a flext account, so will need to cancel the o2 contract and realise that i need to write a letter today to do this, but does anyone know if o2 will let me use the sim (number) as a payg sim once the contract has ended?
I'd appreciate any help.
Cheers :o)

They should do as long as you're not transferring your existing number to your new contract, as this will render your current sim unuseable. Mate of mine did it the other way round, PAYG to contract, so can't see it being a problem.
