Choosing a mobile network used to be just about bars of signal and monthly minutes. But today, our phones are our offices, our entertainment hubs, and our travel companions.
In the crowded UK market, O2 continues to stand out—not just for its 5G coverage, but for the “Extras” that actually make a difference in your daily life. If you’re thinking about switching or upgrading, here are four reasons why O2 remains the gold standard.

1. The Perk of All Perks: O2 Priority
Ask any O2 customer why they stay, and they’ll likely mention O2 Priority. It’s arguably the best loyalty app in the country.
- Gig Tickets: Get 48-hour early access to tickets at O2 venues across the UK (a lifesaver for sold-out tours!).
- Daily Treats: From high-street coffee vouchers to discounted cinema tickets and Greg’s freebies, the app pays for itself if you use it right.
2. EU Roaming: The “Inclusive” Advantage
While many UK networks have reintroduced daily roaming charges for travelling to Europe, O2 has famously held its ground. On most O2 plans, you can still use your data, minutes, and texts in the EU (up to 25GB) at no extra cost. Whether you’re working from a cafe in Spain or trekking through France, O2 keeps you connected without the “bill shock” when you land back at Heathrow.
3. O2 Custom Plans: Flexibility is King
We’ve all been stuck in a 24-month contract that didn’t fit our needs halfway through. O2’s Custom Plans changed the game. They allow you to:
- Choose your upfront cost: Pay more now to lower your monthly bill.
- Pick your contract length: Spread the cost from 3 to 36 months.
- Switch your airtime: Need more data this month? You can step your airtime plan up or down once a month to match your usage.
4. Better Together: The Volt Benefit
If you have Virgin Media broadband at home and an O2 pay-monthly SIM, you get “Volted.” This partnership is a massive win for households:
- Double Data: Your mobile data allowance is instantly doubled.
- Broadband Boost: Your home internet speed gets a bump to the next level.
- WiFi Everywhere: Access to millions of O2 WiFi hotspots across the UK.
5. Commitment to Sustainability
O2 isn’t just looking at your screen; they’re looking at the planet. With their “O2 Recycle” scheme, they’ve paid out millions to customers for old devices, keeping e-waste out of landfills. They are also committed to being a net-zero business, making them a top choice for eco-conscious tech users.

Is O2 Right for You?
- The Music Lover: If you live for live concerts, O2 is a no-brainer for the Priority tickets.
- The Traveller: If you holiday in Europe frequently, the inclusive roaming will save you a fortune.
- The Data-Hungry: If you have Virgin Media at home, the Volt benefits offer unbeatable value.
