Useful tips and information

O2 Voucher Codes

What are the best ways to save at O2?

Finding value for money phone deals is often a tricky business, but not when you zero in on O2 deals. Here are some recent offers to set the scene:

  • £150 off new iPhones with an O2 discount code.

  • £70 off Apple Watches with an O2 promo code.

  • £10 off whatever you buy via an O2 voucher code.

How can I use my O2 promo code?

As you'll see when you browse Voucherbox, O2 runs plenty of discount code promotions and redeeming an O2 code couldn't be easier. Here's how to do so:

  1. Search Voucherbox for an O2 promo code you want to redeem.

  2. Copy the code to your clipboard and click through to the O2 store.

  3. Find items that fit the deal and add them to your basket.

  4. Head to your basket and scroll down. You'll see a box marked "Got a Promo Code?"

  5. Paste your O2 discount code here and press "Update."

  6. Now, your O2 discount should be applied and you can checkout as normal.

What can I do if my O2 voucher code doesn't work?

Sometimes codes might fail to deliver. In that case, any one of these common problems could be to blame:

  • O2 discount code deals are often restricted to certain models or brands. Make sure you've picked a device that fits the deal.

  • Time limits almost always apply, so be sure to purchase O2 products before the deadline arrives!

  • It's important to enter every O2 discount code accurately. If the code doesn't work, you may have accidentally erased a character. Try the Voucherbox code again to see if it works.

Is there a permanent sales section at O2?

Yes, O2 sale bargains are almost always available via the "great deals" section on the O2 Shop. The store also runs seasonal sale pages around Black Friday and Christmas, where many of the best deals are presented.

Can you claim an O2 student discount?

Yes! Members of UNiDAYS, TOTUM, or GRADLiFE can claim a 20% discount when they refresh their O2 contracts via special codes. Use the O2 Refresh service and you'll be led through how to claim your saving.

Do O2 offer free delivery?

Yes, they do. If you need free delivery O2 obliges, providing free home deliveries for all products.

Can you claim cashback at O2?

Yes. If you are a member of the O2 Rewards scheme, you can claim O2 cashback on pay as you go plans. In fact, members can claim as much as 10% of their bills back to spend at O2 or on Ticketmaster tickets.

Is there an O2 loyalty program?

Yes. All O2 customers can sign up for O2 Refresh. This entitles you to free gifts under the O2 Extras program, including Disney+ subscriptions and Audible eBooks. Members also receive special offers at O2 partners, such as live music venues and priority shopping experiences.
