Sim only deal upgrade

[Charlieboyoo]

Hi everyone need a bit of advice,been on a sim only deal since 26/11/18 and the plan doesn’t suit me anymore.im not using the data.Ive seen I can get better sim only deals elsewhere and not tied in.If I correct can I upgrade to a 30day sim only plan so I can leave?or do I need to pay the contract or do a refresh deal?
When I spoke to a guy in o2 earlier he wasn’t very helpful.
Thanks

As I said, it depends on your history, not your credit rating.

Not true actually

PAYG, 2 year contract with the S3 and then Sim only.
