Ending my contract and switching to sim only

[Anonymous]

Hi

My 24 month contract ends next month. I don't want an upgrade, I'd ideally like to keep my phone and number and get a sim only deal (still on o2) How do I cancel my contract once the 24th month is up so I don't get charged afterwards? Also once I buy a sim only deal, does the monthly cost start from the buying date or can I choose what date it starts?
Please help

At Vodafone, as your contract ends you can change to a cheaper SIM only contract with a few clicks at the website.O2 have let me down by obviously difficulting the change to a SIM only plan to keep charging more. At my O2 account, I can easily renew my contract with a new and more expensive phone, but not reference whatsoever about the option to move to a similar plan for a lower SIM only plan. I'm leaving O2!

Just call them on 202 and choose any of the simo plans.
It really isn't difficult at all and you don't even need a new sim card.

I see your point but it's so easy to do on the shop page or by calling 202 which I did myself.
