How do I cancel my contract (it has just rolled over) so I can switch networks?

[cpurple2015]

I'm switching to a SIM only contract with another provider.  I've requested a PAC code from O2 and given this to the new network.  Is that all I need to do?  It says not to call unless urgent due to Covid so feel a bit lost. 

Thanks

@cpurple2015 You've done all you need to do. Do not cancel your Direct Debit with O2 until you receive a final bill.
