VOXI is Vodafone's youth-oriented SIM-only brand, now operating under VodafoneThree following the 2025 merger. Its defining feature is unlimited data for a named list of social media and streaming apps that does not count against the plan's main data allowance, aimed squarely at younger users whose usage concentrates on those platforms. Plans are rolling monthly with no annual contract, and coverage follows Vodafone's network. |

Ownership and positioning
VOXI is Vodafone's youth-focused SIM-only brand, built on Vodafone's own radio network and now operating within VodafoneThree since the 2025 merger with Three. Where Smarty (a Three brand) competes on raw data allowance, VOXI competes on a different axis: unlimited use of specific social and streaming apps that does not touch the plan's core data.
The named-app list has changed over time as social platforms have evolved, and covers the major social, messaging and some streaming services at any given point. The current list is published in VOXI's own terms and is worth checking directly, since exclusions can shift.
How the unlimited-app data model works
The mechanic is straightforward: usage inside the named apps does not count against the plan's core data allowance, which means a customer whose phone use is concentrated on those platforms can run a comparatively small core data plan and still use social media and messaging without limit. General browsing, other apps, and anything outside the named list draws from the core allowance as normal.
VOXI Extra sits above the standard tier, adding a larger core data allowance for customers who also do meaningful general browsing, video calling or streaming outside the named apps, while keeping the same unlimited-app mechanic.
Coverage, network and switching
VOXI runs on Vodafone's radio network rather than Three's, so its coverage profile differs from sibling brand Smarty and should be checked independently through Ofcom's coverage tool using Vodafone as the network. Following the VodafoneThree merger, Vodafone's own network is subject to the same integration and investment programme discussed in Kael Tripton's Three network review, with coverage expected to improve as spectrum and infrastructure are combined.
As a rolling monthly product, leaving VOXI needs only a PAC request via the standard text-to-switch process, with no early-exit fee since there is no fixed term to break.
Who VOXI suits
The plan fits its target market cleanly: users whose data consumption concentrates heavily on social media, messaging and a defined set of streaming apps get outsized value from a modest core allowance. It fits less well for users whose usage is spread across many apps and services outside the named list, where a large-allowance plan from a network operator or Smarty on Three may work out more straightforwardly.

Frequently asked questions
Which apps get unlimited data on VOXI?
VOXI publishes a specific list of eligible social, messaging and streaming apps in its plan terms, and usage inside those apps does not count against the core data allowance. The list is reviewed periodically, so checking VOXI's current terms before relying on it for a particular app is worthwhile.
Is VOXI the same network as Vodafone?
Yes: VOXI runs on Vodafone's own radio network. It is a separate brand from Smarty, which uses the Three network, even though both now sit within the same VodafoneThree company.
Does VOXI require a contract?
No: VOXI plans are rolling monthly SIM-only deals with no fixed term, so they can be changed or cancelled at any monthly renewal point.
