My contract

[McG3]

I am seriously considering cancelling my account with you and moving to another provider on a sim only basis.

O2 are far too expensive and I feel as a long time customer I am being taken advantage of.

@McG3 This is not O2. This is a customer community.

You can use USwitch to get a better deal.
https://www.uswitch.com/mobiles/compare/sim_only_deals/o2/
Choose the deal you want.
This will automatically redirect you to the O2 website.
Just follow the prompts and choose the UPGRADE option.
Complete the deal and nothing on your account changes except the tariff at the new cheaper cost.
Payment date is the same and your next bill will be at a cheaper rate and will be made up of the pro rata cost of your old tariff and your new tariff.
The change should show in My O2 within 24 hours.
Volt benefits will still apply as will possibly a 3 month extra such as Disney+.

If you still want to cancel see this guide: Cancelling your contract - An updated guide - O2 Community
