O2 Promo Code & Discount Code March 2026

More Ways to Save Money at O2

O2's built a proper ecosystem of savings that goes way beyond just competitive phone prices. From their Priority rewards program that delivers weekly treats and exclusive perks to family discounts that slash airtime costs, there are clever ways to cut your mobile spending while getting more value. Whether you're after the latest Samsung Galaxy or just want a SIM-only deal that doesn't break the bank, O2's stacked their offers to reward loyalty and smart shopping.

Apply Your O2 Discount Code, Step by Step

Ready to save on your O2 order? Here's exactly how to apply any discount code you've found:

1. Add your chosen device or SIM plan to your basket and review your selection
2. Look for the "Got a promocode?" box in your basket — it's usually near the order summary
3. Enter your discount code exactly as provided, watching for any capital letters or special characters
4. Click "Update" to apply the savings — your new total should appear immediately
5. Complete your order before the code expires, as some offers have limited availability

If your code isn't working, double-check you meet any minimum spend requirements or plan eligibility. Some discounts only apply to specific tariffs or new customers, so read the terms carefully. Student and NHS discounts require separate verification through O2 Open rather than checkout codes.

Get Weekly Treats & Cinema Discounts with Priority Rewards

O2's Priority program is genuinely brilliant — it's like having a VIP pass to the UK that actually saves you proper money. Available free to all O2 mobile and Virgin Media broadband customers aged 16+, Priority delivers weekly treats and exclusive experiences that add up to real savings.

The Greggs offer alone is worth joining for. Claim a hot drink (RRP £4.20) or savoury treat (RRP £3.95) for just £1 every week. Do this monthly and you're saving over £12 on your coffee habit. Vue cinema tickets are even better value — four tickets for £18 when they normally cost £13.99 each. That's nearly £38 saved if you're a regular movie-goer.

But Priority goes beyond food and films. Members get 48-hour early access to presale tickets for thousands of UK events, plus VIP treatment at O2 venues including queue jumps, free cloakroom service, and exclusive lounge access. Blue Mondays bring thousands of prize drops and limited-time rewards every week.

For frequent travellers, the savings can be particularly impressive — save up to £150 monthly on lastminute.com when spending £1,500. While this high-value travel perk helps achieve the advertised "up to £200 monthly" savings potential, most users will see consistent value through the weekly Greggs treats, Vue discounts, and event perks that make Priority genuinely worthwhile.

Get 20% Off Airtime with Multisave Family Plans

Families can slash their mobile bills with O2's Multisave program, which gives you 20% off the airtime plan for every additional Pay Monthly connection you add to your account. You can add up to 20 numbers to your group, making this perfect for large families or small businesses.

Here's how the maths works: a £16 monthly airtime plan drops to £12.80 with Multisave — that's £3.20 saved every month, or nearly £39 annually per line. Multiply that across multiple family members and you're looking at substantial savings.

Setting up Multisave is straightforward. Buy your phone, tablet, or SIM directly from O2 on an eligible tariff, then sign into My O2 and navigate to 'Multisave' from the main menu. Your discount applies within three working days. The first number you add becomes your 'lead connection' and won't be discounted, but every additional eligible number benefits from the 20% reduction.

Remember that you need to connect or upgrade within the last 28 days to be eligible, and the discount only applies to airtime costs — not calls, texts, or data usage outside your included allowances. Ultimate Plans aren't eligible for Multisave, but they come with lifetime O2 Extras instead.

Free O2 Extras Worth Hundreds Annually

O2 Extras transform your mobile plan into an entertainment powerhouse. Choose from Disney+ Standard, TNT Sports, Amazon services (Prime, Music, or Audible), Xbox Game Pass Ultimate, or security packages — all included with your plan rather than paid separately.

The value here is substantial. Disney+ Standard normally costs £7.99 monthly, while Amazon Prime is £8.99 monthly. Xbox Game Pass Ultimate runs £12.99 monthly. Getting any of these free for 3-6 months (Classic and Plus Plans) or for life (Ultimate Plans) represents genuine savings of £100+ annually.

Classic and Plus Plan customers get their chosen Extra for 3-6 months, while Ultimate Plan customers enjoy their Extra for the entire contract duration. You can add multiple Extras to your package through My O2, though additional ones will be added to your monthly bill.

The international options are particularly clever for frequent travellers. The International Bolt On lets you chat with international numbers from just a penny per minute to over 200 countries, while the O2 Travel Inclusive Bolt On covers roaming across 27 destinations outside Europe, including the USA, Canada, Australia, New Zealand, and Mexico.

Turn Old Tech into Cash with O2 Recycle

O2 Recycle accepts a surprisingly wide range of devices and offers decent trade-in values that can significantly offset your upgrade costs. They'll take phones, tablets, AirPods, MacBooks, wearables, and even games consoles — basically anything electronic that's gathering dust.

The trade-in values are competitive: iPhone 15 Pro Max fetches up to £355, iPhone 14 Pro Max up to £300, and iPhone 15 Pro up to £330. Even older models hold value — an iPhone 11 can still get you up to £66, while an iPhone 13 Pro Max is worth up to £225.

The process is refreshingly simple. Search for your device at o2recycle.co.uk to get an instant estimate. If you're happy with the quote, complete your order and prep your device by backing up data and sorting security settings. O2 provides free packaging and labels, or you can use your own. Once they receive your device, it's securely wiped and you're paid within 3-5 days.

Your quote is locked in for 7 days, giving you time to get everything sorted. If your device's condition doesn't match your description, they'll email a revised quote — you can accept the new offer or have your device returned for free.

Free Next-Day Delivery on Everything

O2 makes getting your new tech refreshingly simple with free home delivery on all devices, SIMs, and accessories. Order before midnight Sunday through Thursday and you'll get next working day delivery on devices — no minimum spend required.

If you prefer collecting in-store, Click & Collect is available with same-day pickup if your chosen item is in stock. If it's not immediately available, the store can order it for you or you can choose a different location. Orders are held for seven days, giving you flexibility around collection.

For collection, bring your 4-digit reference from the confirmation email plus photo ID (passport or UK driving licence). Third-party collection is possible but requires the confirmation email, the collector's photo ID, and ID confirming your identity too.

The delivery process is streamlined — no signature required, just a photo taken by the courier upon delivery. Some orders need a 4-digit PIN from the courier, but this is provided in advance. SIMs and accessories aim for delivery within three working days, making O2 one of the faster networks for getting you connected.

Student and NHS Discounts Worth Hundreds

20% Off Airtime Plans for Students

University students can save 20% on both airtime plans and selected accessories through O2's student verification system. This applies to O2 Refresh contracts for handsets, tablets, and mobile broadband, making it perfect for students who need reliable connectivity for studies.

The discount requires verification through O2's student portal, where you'll get a unique discount code. Unlike some networks that offer temporary student deals, O2's 20% reduction applies to your ongoing airtime costs, delivering consistent monthly savings throughout your studies.

Up to 25% Off for NHS and Key Workers

NHS workers get up to 25% off their airtime plans through the O2 Open programme, while teachers can claim the same discount by logging into O2 Open with verification. Emergency services and state school employees are also eligible for these substantial savings.

The discount structure is tiered: 25% off for plans with 3GB or more of data, and 15% off for plans with less than 3GB. You must apply within 28 days of starting your plan and verify your eligibility through the O2 Open portal. This isn't a temporary promotion — it's an ongoing benefit that recognises key workers' contributions.
