Answer first: As of 16 September 2026, VOXI’s own shop is running a limited 3× data offer on selected rolling plans until 30 September 2026. The £10 plan jumps to 60GB (was 20GB; reverts to 20GB after the offer). The £15 plan jumps to 140GB (was 35GB on the prior promo ladder; reverts to 25GB after 30 Sep). Both are 30-day rolling, price-locked while you stay on the plan, with Unlimited Social on £10 and Unlimited Social + Music + Video on £15. Verified on voxi.co.uk/charges and voxi.co.uk/sim-only-plans. Nest currently has zero VOXI affiliate products, so SwitchSquid will not invent Awin pclicks — check VOXI’s shop for the promo, then use Nest-tracked rolling alternatives below if you want a tracked compare click.

What is the VOXI 3× data deal (September 2026)?
VOXI is Vodafone’s youth-leaning MVNO-style brand on the combined Vodafone / Three “Nation’s Network” stack. Plans are online-only, 30-day rolling subscriptions, cancel anytime, with unlimited UK calls and texts plus a general data bucket. The twist that makes VOXI famous is zero-rated social (and music / video on higher plans): selected apps do not eat the general allowance in the UK when you use the listed apps correctly.
The September promo VOXI labels as a 3× data offer on selected plans is short and sharp:
- Ends: 30 September 2026
- £10 plan: general data 60GB (was 20GB). After 30/09/2026 the £10 plan offer reverts to 20GB. Includes Unlimited Social.
- £15 plan: general data 140GB (was 35GB on the previous promotional print). After 30/09/2026 the £15 plan offer reverts to 25GB. Includes Unlimited Social + Unlimited Music + Unlimited Video.
- Contract: rolling 30-day; VOXI also prints price-lock language (monthly price stays the same while you stay on that plan).
- eSIM: available alongside physical SIM.
On the live plans tiles, VOXI may badge the £10 tile as “3x Data” and the £15 tile with a larger multiplier graphic — the legal footnote on Charges still groups both under the same “VOXI 3x data offer on selected plans” end date. We quote the footnote, not the marketing badge maths.
VOXI 3× vs other rolling SIM deals UK — comparison table
Ofcom’s 2026 Communications Market Report figure, as commonly summarised on comparison hubs, puts typical UK mobile use around 11.8GB a month. VOXI’s promotional 60GB / 140GB buckets are therefore several times average use — useful if you hotspot, commute on data, or keep maps and email off Wi-Fi. Social / music / video zero-rating can shrink how fast the general bucket falls, but third-party ads inside apps and non-listed destinations still burn general data.
| Deal (checked 16 Sep 2026) | Term | £/mo | General data | Extras / catch | How to buy |
|---|---|---|---|---|---|
| VOXI £10 3× promo | 30-day rolling | £10 | 60GB (reverts to 20GB after 30 Sep) | Unlimited Social; price lock while on plan; EU roaming needs a pass | Check VOXI shop → |
| VOXI £15 3× promo | 30-day rolling | £15 | 140GB (reverts to 25GB after 30 Sep) | Unlimited Social + Music + Video; was 35GB on prior promo print | Check VOXI shop → |

Who the VOXI 3× deal is actually for
SwitchSquid writes for people who already own a phone and care about the airtime bill, not a handset finance brochure. The VOXI promo earns a place on a September shortlist when:
- You want monthly exit freedom after O2’s affiliate 30-day cull (16 Sep 2026 23:59) and you prefer Vodafone-side radio over Three-stack MVNOs.
- You live inside Instagram / Snapchat / WhatsApp / Facebook / X / Pinterest / Messenger enough that Unlimited Social meaningfully protects the general bucket.
- You can activate before 30 Sep 2026 and you understand the post-promo revert (20GB on £10, 25GB on £15) — otherwise you are buying temporary headroom, not a forever 60/140GB tariff.
- You are happy buying on VOXI’s own site. Nest has no VOXI product rows today, so we will not print fake pclinks. That is an honesty constraint, not a ranking slur.
Skip VOXI 3× if you already blow past social zero-rating with hotspot tethering all day, if you need seamless EU roaming without buying a pass, or if you want a tracked affiliate checkout from SwitchSquid this week — in that case the Nest giffgaff Unlimited rows above are the cleaner click path.
Unlimited Social, Music and Video — what counts (and what does not)
VOXI’s own FAQ language is clearer than most marketing copy. In the UK, Unlimited Social covers Snapchat, Instagram, WhatsApp, Facebook, Twitter/X, Pinterest and Facebook Messenger without eating general data. Unlimited Music covers apps such as Spotify, Apple Music, Amazon Music and others listed on VOXI. Unlimited Video covers YouTube, Netflix, Prime Video and My5 among the listed set. Third-party adverts, in-app browsers, and non-listed destinations still use general data. Voice and video calls inside social apps are not included in Unlimited Social. Apps must be up to date or usage may fall onto the general allowance. Subscriptions to Netflix / Spotify etc. are separate.
That is why a 60GB general bucket with Unlimited Social can feel larger than a plain 60GB SIM from another brand — and why a heavy hotspot user can still empty 140GB. Rank the lifestyle, not the sticker.
Cash maths: £10 / £15 rolling vs locked unlimited
Assume you take the promo and stay a full year without cancelling:
- VOXI £10: £120/year. Promo data is 60GB only while the offer rules say it lasts — VOXI’s footnote points the post-30-Sep £10 plan back to 20GB. Treat 60GB as a window, not a promise forever.
- VOXI £15: £180/year for the promo 140GB window, then the printed revert is 25GB on that price point unless VOXI launches a new offer.
- giffgaff Unlimited rolling £20 (Nest 585420): £240/year if you stay monthly — more cash than VOXI £15, but true unlimited general data (subject to fair use) and a Nest-tracked Awin click.
- giffgaff Unlimited 18m £14 (Nest 585419): £168 over 12 months of the term — often the better “I refuse to watch a data meter” answer if you accept an 18-month lock and the 2 Oct 2026 promo cliff.
None of those figures include roaming passes, add-ons, or mid-offer retailer changes. VOXI requires a European Roaming Pass to roam; while roaming, Unlimited Social / Music / Video usage comes out of the plan’s data allowance and sits under a 20GB fair-usage style limit per 30-day plan per VOXI’s Charges text.

How to join VOXI before the 30 Sep cliff
- Order a free SIM or set up eSIM from VOXI’s plans flow.
- Create the online account and pick the £10 or £15 plan while the promo still prints 60GB / 140GB.
- To keep your number, text PAC to 65075 from your old SIM, then enter the code during activation (standard UK switching).
- Confirm APN / data settings if needed (VOXI documents texting WEB to 40127 on Wi-Fi for settings pushes).
- Calendar a reminder for late September: if 20GB / 25GB after the revert is too tight, cancel or move before the next 30-day bill.
VOXI also runs loyalty “Drop” rewards and, separately, a Friends-with-Benefits double-rewards window (07 Jul 2026–07 Oct 2026 per the shop footnote). Those are nice-to-haves; they do not change the data revert maths.
Best rolling SIM deals UK angle — where VOXI sits after O2’s 30-day exit
September 2026 is awkward for rolling SIM shoppers. O2’s affiliate catalogue is removing 30-day / Classic rolling SIMO (hard stop 16 Sep 2026 23:59). That pushes flexible buyers toward MVNOs we can still track in Nest — especially iD on Three and giffgaff on the EE consumer stack — or toward retailer-only brands like VOXI when Nest has no feed row.
Practical ranking rule we use on SwitchSquid this week:
- Need tracked affiliate checkout today → Nest giffgaff Unlimited 585419 / 585420 (and other live Nest SIM rows on related guides).
- Need Vodafone-side rolling + social zero-rate + temporary fat data → VOXI shop 3× until 30 Sep, then reassess.
- Need O2 radio specifically → live 12-month O2 Classic paths on the O2 alternatives guide, not a dead 30-day tile.
We will not pretend Nest can convert a VOXI click until Deals / feed ingest adds VOXI products. Until then, retailer check + Nest secondary alternatives is the compliant mix.
FAQs
When does the VOXI 3× data deal end?
VOXI’s Charges footnote states the offer ends 30/09/2026. After that, the £10 plan offer reverts to 20GB and the £15 plan offer reverts to 25GB. Confirm the live tile on voxi.co.uk before you pay — retailers can pull promos early.
Is the £15 plan really 3× data?
VOXI markets a “3x data offer on selected plans.” The £10 jump (20GB → 60GB) is a clean 3×. The £15 jump prints 140GB (was 35GB on the prior promo; reverts to 25GB). Treat the legal end date and GB figures as authoritative; ignore badge arithmetic if the tile says “4x” creatively.
Does Unlimited Social use my 60GB or 140GB?
In the UK, listed social apps should not eat the general allowance when used as intended. Ads, non-listed sites, outdated apps, and voice/video calls inside social can still draw general data. Music and Video zero-rating only apply on the plans that include them (£12+ music, £15+ video per VOXI).
Can I cancel VOXI anytime?
Yes — plans are 30-day rolling subscriptions. Cancel before renewal if the post-promo allowance is too small. Price-lock language means the monthly price stays put while you remain on that plan; it does not freeze the promotional data multiplier after the offer ends.
Why are there no “Get VOXI deal” Awin buttons on this page?
Nest’s product database currently returns zero VOXI rows for affiliate mid tracking. SwitchSquid policy is not to invent pclinks. Primary VOXI CTA = official shop. Secondary tracked CTAs = live Nest giffgaff Unlimited deepLinks (products 585419 and 585420, Awin a=911601, m=3599).
Is VOXI good for EU roaming?
Not “set and forget.” VOXI requires a European Roaming Pass. When roaming, unlimited social/music/video usage is deducted from the plan data allowance and sits under VOXI’s stated fair-usage style limit. If roaming is your main job, compare specialists on our EU roaming SIM guide and Nest-tracked alternatives.
How does this compare to giffgaff Unlimited at £14 / £20?
giffgaff’s promo (to 2 Oct 2026 23:59 per help.giffgaff.com) buys uncapped general data (fair use still applies) with Nest-tracked checkout. VOXI’s promo buys a cheaper monthly cash outlay with social zero-rating and a temporary fat general bucket on Vodafone-side radio. Pick social-heavy + exit freedom (VOXI shop) vs meter-free general data + tracked click (Nest giffgaff).
Will my price rise every April?
VOXI prints price-lock messaging for the plan price while you stay subscribed. Always re-read the latest terms on voxi.co.uk/terms at purchase — do not rely on a blog memory of last year’s inflation clause style from other networks.
Bottom line
If you want one of the best rolling SIM deals UK shoppers can still grab mid-September 2026 without a long lock, VOXI’s 3× data window to 30 Sep is genuine on the retailer’s own pages: £10 → 60GB, £15 → 140GB, social (and music/video on £15) zero-rated in the UK, cancel monthly. Just walk in with eyes open on the post-offer revert and the Nest gap — no fake affiliate links from us. Prefer a tracked unlimited alternative today? Use the Nest giffgaff buttons.
