Volt customers can get 160GB of monthly data for just £10, double what the plan normally includes.
Those extra gigabytes arrive through O2’s 80GB SIM-only plan, an online exclusive costing £10 a month, which jumps to 160GB at no extra cost for anyone already with both Virgin Media and O2 via Volt.

Get 80GB of 5G data for just £10 a month with this O2 SIM only deal
This O2 SIM only deal brings a generous 80GB of 5G data down to just £10 a month, with unlimited UK minutes and texts also included.
View DealSpread across the month, that £10 works out at just over 6p per gigabyte for Volt members, and because the extra 80GB costs nothing on top, the whole allowance lands for the same price as the regular 80GB allowance, effectively doubling what every pound buys.
Commitment stays light too, as the plan runs on a one-month rolling contract. You stay for as long as it suits you and keep full control over your monthly spending, with a fresh 160GB of data arriving every month you remain with O2.
Month after month, 160GB gives plenty of room for streaming series on the commute, joining video calls away from Wi-Fi, downloading playlists before a trip, and scrolling social feeds without keeping one eye on how much data is left before payday.
All of that streaming gets a lift from 5G in selected areas, while unlimited UK minutes and texts come as standard, so calling family or messaging friends throughout the day never eats into the data you have set aside for everything else.
Beyond your phone, Volt also brings boosted broadband speeds and more to households with both Virgin Media and O2, which makes the O2 80GB Mini SIM only plan one piece of a wider package that rewards keeping everything together.
For Volt customers, the O2 80GB Mini SIM only plan hands over 160GB for £10 a month, doubling the allowance with an extra 80GB at no cost, all on a monthly contract that keeps your options open whenever your needs change.
