O2 FAQs
Are there any O2 discount codes right now?
There are no live O2 offers at the moment. We add new codes and deals as soon as we find them.
How do I use an O2 discount code?
Click "Get Code" on the offer to reveal and copy the code. Shop at O2 as normal, then paste the code into the promo or discount code box at checkout and check the saving before you pay.
Why isn't my O2 code working?
Check the end date and terms on the offer. Codes often need a minimum spend, may exclude some brands or sale items, can be for new customers only, and usually only one code works per order. If it still fails, try another offer on this page.
When do O2 offers end?
None of the current O2 offers end in the next 7 days. Each offer shows its end date where the retailer has given one; where no date is given, check the terms at O2.
