In all honesty I would ask customer service to switch your number to a PAYG sim card.
That way, you know 100% that your monthly contract has ended as it can be a bit risky when not porting your number away from the network.
Def go this way, if you want an O2 SIM - giving verbal or written notice these days is fraught with pitfalls .
Personally I'd get a sim from another provider. Three are probably best for this - you can order a 321 SIM for free. Top up with a fiver and check if the SIM works in the old O2 handset - if it doesnt O2 will unlock your device for free as you were pay monthly - or rather you can do this yourself online in MyO2 under device details whilst you are still a customer.
Then request a pac code - by calling CS on 202 from the 02 phone with the 02 sim in and telling them you want a pac code. This wil start the clock ticking on your 30 days notice. You HAVE to use the Pac before 30 days are up, or it expires. If you got a three Sim you can just go onto the three website and fill in a really simple form to start the porting process, This takes a day or so.
Test to make sure the old number is transferred properly and your O2 contract will have cancelled. My O2 will show it as a disconnected line and give details of your final bill, which might be a credit. Wait till your payment goes out or you get your credit and then cancel the direct debit.
You are now the proud owner of an unlocked handset with £5 PAYG credit on a different network and until you make your first call its cost you precisely nothing.
