Can only be done on a big bundle, not a rolling plan.

You can't for a rolling plan it is done via a continuous payment authority 

For a Big Bundle have a look here https://www.o2.co.uk/help/pay-as-you-go/big-bundles

Does this mean that I have to order a new SIM card? Can I not just purchase a big bundle on my current SIM?

Yes, you can, the link I gave you has the details on how to do this... @Grim
