Sim plan

[Helen26]

My sim o2 plan has expired, contacted o2 as I saw a cheap one on uswitch but o2 say it is not available, but it still is on uswitch,my query is can I purchase the cheap o2 sim plan on uswitch and still stay on o2 with my same number?

Only for new contracts or upgrades, but, Use USwitch
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 cat 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+
