About O2

Established in 1985 and rebranded O2 to 2002, this UK-based mobile network connects with over 25 million other connections nationwide. Pay monthly and pay as you go deals are available on SIM only and device contracts, covering brands like Apple, Samsung and Google. The service also offers benefits via its Priority program, such as priority tickets to events, money off at affiliated stores and other offers. You can keep an eye on your account via the app and website, track usage and upgrade devices when you need to. Over 99% of the UK population is covered by 4G, and the 5G network is growing in towns and cities too.

How Do I Apply an O2 Promo Code at Checkout?

Choose your device or plan: Head over to o2.co.uk and pick a product, like the iPhone 15 or a SIM Only deal. Pick the storage, colour and plan, then click 'Continue'.
Check your basket: On the 'Your Basket' page, you'll see the 'Got a promo code?' link just underneath the list of products and the total.
Paste the code: Click 'Got a promo code?' to open up the text box. Enter your discount code from DontPayFull and click 'Apply'. If it's valid, the discount will appear on the order summary instantly.
Checkout: Once you've applied the promo code, click 'Checkout' to the next step. You can sign in or create an O2 account to pay for your order. If you're an 'O2 Priority' member, check out any exclusive offers before you pay.

Why is my O2 discount code not working and what should I do next?

Check plan type (payg vs contract): Codes work only on Pay Monthly or Pay As You Go. If you're on a SIM only contract, the code can't be used if it's limited to device bundles or upgrades.
Existing customer limits: This includes plans that contain existing customers or upgrades. If you are already on a plan, try the code with a new account or when you switch devices.
O2 priority restrictions: O2 Priority codes are either usage limits or app-based redemptions. Double check that you are logged in via the Priority app, not just the website.
Basket configuration: Adding accessories or insurance cancels the offer. Remove any add-ons and apply the code with the main item in your basket.

O2 Discount Code and Savings FAQ for Smarter Shopping

How can I get the best discount on O2 Refresh packages?

Save up to £300 over 36 months by selecting a plan with a lower upfront payment and using discount codes during sales such as Black Friday or Summer Sale. Throw in trade-in deals for extra savings.

Does O2 offer trade-in deals that can be used with discount codes?

Absolutely. Their 'O2 Recycle' scheme allows you to earn up to £500 for selected devices. You can then use this credit towards your new purchase when you redeem your order.

Can you use O2 Open discount with other offers?

No. The O2 Open discount, which gives up to 25% off Airtime Plans for employees of partner companies, cannot be combined with other promotional codes or offers.

How do I get student discount on O2?

Students signed up to UNiDAYS can enjoy 20% off Airtime Plans on certain devices. Simply verify your student status with UNiDAYS and apply before you pay for your plan.

Are there any app-only discounts or codes?

Certainly. The My O2 app sometimes offers app-only discounts and early access deals. These discounts do not apply on the main site.

Can O2 Priority members save more?

O2 Priority members can get early access to event tickets and exclusive limited time offers, these are usually for experiences rather than device upgrades.

Can I find working O2 discount codes on DontPayFull?

Yes. We are constantly checking and refreshing our promo codes, including seasonal and short-term deals. Make sure to double check the code and any terms here first.
