How to get in touch with o2

[Rachienee88]

Hi,
I recently ordered a new sim for a 12 month contract but then realised I could just change the tariff which I have done.
I no longer want the SIM card , how can I let o2 know? Is the best way to ring them?

Many thanks

You'll need to call customer service.
Numbers here Guide: Coronavirus Community Help and Support 
When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
8.00am is the best time to call if you can.

Or just return sim under change of mind policy when you receive it.
