O2 Volt isn’t just another add-on or loyalty perk—it’s a genuinely useful bundle that gives existing O2 mobile and Virgin Media broadband customers some serious upgrades, completely free. If you’ve got both services under one roof, you’re probably sitting on some valuable extras you haven’t claimed yet.
In this no-nonsense guide, we’ll break down what O2 Volt is, what you get, how it works, who qualifies, and why it might be the most underrated telecom deal in the UK right now.
🌟 What Is O2 Volt?
Launched in October 2021 after the merger between O2 and Virgin Media, Volt is a cross-brand benefit scheme. It links your mobile and broadband accounts, and in return, you get a bunch of boosts.
There’s no catch. No price hike. Just better value for staying within the Virgin Media O2 family. O2’s Official Website explains more about O2’s services and their specific plans, so you can get the full details on what’s available before activating Volt.
Here’s what Volt gives you:
📊 What Do You Get with O2 Volt?
✔️ Double Mobile Data
Once Volt is activated, your O2 mobile plan’s data allowance doubles automatically. That includes:
- SIM-only plans
- Pay-monthly phone contracts
- Family accounts (everyone linked gets the benefit)
And it’s not just a promo bolt-on—your plan actually updates, no expiry date.
✔️ Faster Virgin Media Broadband
Your broadband plan is boosted to the next available speed tier:
- M125 ➔ M250
- M250 ➔ M350
- M350 ➔ M500
Already on the fastest tier? You won’t get an upgrade, but the other Volt perks still apply.
✔️ Roaming in 75 Destinations
Eligible mobile plans get O2 Travel Inclusive Zone, which means you can use your UK minutes, texts, and data in places like:
- USA
- Canada
- Australia
- Mexico
- Turkey
- Most of Europe
That’s a game-changer if you travel for work or holidays. If you need a sim for travelling abroad, check our sim only offers.
✔️ Family Plan Perks
Anyone you’ve added to your family plan gets the same double data. Perfect for households with multiple phones on O2.
📃 Who Can Get O2 Volt?
To activate Volt, you need:

| Virgin Broadband | Must have an active Virgin Media broadband account |
| Same Address | Both services must be registered to the same home address |

🔍 Which Plans Include O2 Travel Inclusive?

- Or a SIM-only plan that costs £30/month or more
You can check your plan details via the My O2 app or website.
⚠️ Things to Keep in Mind

- ❌ If you cancel either O2 or Virgin Media, your Volt perks vanish
- ✔️ Works with 4G and 5G plans—no speed caps
- 🇪🇺 EU data roaming cap: 25GB/month max for fair use
- ✔️ You can stack Volt with other perks like O2 Priority or Extra Offers

With Virgin Media rolling out full fibre (FTTP) more widely, we could see even better broadband boosts included in Volt.
There’s also speculation about Volt+ entertainment bundles down the line—maybe Netflix, Disney+, or even Virgin TV add-ons.
💬 What Customers Say
“I switched from BT to Virgin just for Volt. My O2 SIM now gets 60GB instead of 30GB, and broadband went from M125 to M250 without paying a penny more.” — Alex, Manchester
“I go to the US every month for work, so the free roaming saves me £50-£80 each time. Volt was a no-brainer.” — Priya, London
🤔 Final Thoughts: Is O2 Volt Worth It?
100%. If you’ve already got Virgin Media broadband and an O2 mobile plan, there’s no reason not to activate Volt. You’ll get:
- Double your mobile data
- Faster broadband speeds
- Free roaming in major travel destinations
- Perks that benefit your whole household
In 2025, Volt remains one of the most valuable and underused perks in UK telecom. If you’re eligible, switch it on—you’re leaving free value on the table otherwise.
