O2 FAQs
Can I get free delivery?
Yes. If you buy a phone or tablet, order by midnight and you’ll receive free next-day delivery to your home, in non-remote areas. The delivery team will send you a text on the day to let you know when your order is arriving, so you can always reschedule if you aren’t going to be in.
If you order a SIM or accessory, you can also enjoy free delivery and can expect your order to arrive within 5 working days. Premium delivery starts at £4.99, you can also click & collect within minutes if your device is in stock at your local O2 store.
Does O2 do student discount?
Yes. Students can save 20% off Airtime plans when they buy a connected phone or tablet, plus 20% off selected accessories too. To receive your unique basket code, simply sign in to your UNiDAYS, GRADLiFE or TOTUM app. This discount isn’t available on in-store purchases so make sure you order online!
Why is my O2 discount code not working?
There can be many reasons why a code doesn’t work. The most common reasons are:
- It may not be valid for the specific phone or sim card you have in your shopping basket.
- The code may only be valid for new customers.
- The phone / sim card may already be discounted or on sale.
- The code may have been expired early due to limited availability.
It’s best to thoroughly read the individual terms and conditions for each code to avoid disappointment.
If your code still doesn’t work and you’ve checked all the above points, then please contact us via our Contact page and we will try our best to help you.
