In 2026, a mobile contract is more than just a monthly bill—it’s a membership. If you’re on O2 UK, you’re sitting on a goldmine of rewards that many users completely overlook.
If you aren’t saving at least £20–£30 a month using your network perks, you’re doing it wrong! Here is how to squeeze every bit of value out of your O2 plan.
1. Master the “Priority” Tuesday (and every other day)
The O2 Priority app is the undisputed heavyweight champion of loyalty schemes. But it’s not just about the big concerts.
- The High Street Save: From £1 coffee at Greggs to discounted lunch deals at Meal Deal hubs, using Priority just twice a week for food and drink can save you £100+ a year.
- Entertainment on Us: O2 frequently partners with streaming services like Disney+ or Amazon Music. Check your “Extras”—many plans come with 6 months of a premium subscription included. That’s roughly £50–£60 in savings right there.
2. The “Volt” Advantage: Double Everything
If you have Virgin Media Broadband at home, you are literally leaving money on the table if you haven’t activated Volt.
- The Math: You get double the mobile data for the same price. This means you can drop down to a cheaper O2 airtime plan and let the Volt “double up” feature bring you back to your high data limit.
- The Speed: Your home broadband gets boosted to the next speed tier for free. It’s the ultimate “power couple” move for your wallet.
3. Roam Like You’re at Home
While other UK networks are charging £2–£2.50 per day to use your phone in Europe, O2 (on most plans) still includes EU Roaming.
- The Vacation Hack: On a 10-day holiday in Italy or Spain, a family of four on O2 could save nearly £80 compared to being on a network that charges for roaming. That’s a nice dinner out on the house, courtesy of your network.
4. Customise Your Way to a Lower Bill
O2’s Custom Plans aren’t just for buying fancy phones; they’re for financial flexibility.
- Overpayment: Had a good month? You can pay off a chunk of your “Device Plan” early to lower your monthly outgoings.
- Airtime Swap: If you find you’re using less data than you thought, O2 allows you to step down your airtime plan once a month. Don’t pay for what you don’t use!
5. O2 Recycle: Get Paid for Your “Drawer Phones”
Most of us have an old iPhone or Samsung gathering dust in a drawer. O2 Recycle isn’t just for O2 customers, but as a member, you often get “top-up” bonuses when trading in for a new device. It’s an instant credit toward your next bill or a new pair of AirPods.
Is it Worth it?
When you add up the Priority perks (£15/mo), Inclusive Roaming (£20/trip), and Volt Data Doubling, an O2 contract often pays for itself within the first week of the month.
