VOXI’s September 3× data offer on selected 30-day rolling plans was advertised to 30 September 2026. In that window the £10 plan included 60GB (baseline 20GB) with Unlimited Social, and the £15 plan included 140GB (baseline 25GB) with Unlimited Social + Music + Video. Both include unlimited UK calls and texts. For October, check VOXI’s own plans page for today’s allowances; if you want a tracked high-data alternative now, compare the live Mozillion Pay Monthly Plus and 150GB plans below.
Mozillion Pay Monthly Plus 100GB — £81.25 + £3.25/mo (24 months)
- 100GB UK data, unlimited UK calls & texts
- £81.25 upfront then 23 × £3.25 — £156 over 24 months (about £6.50/mo equivalent)
- Confirm the live Mozillion plan page and basket total before you pay

VOXI’s shop footnote gave 30 September 2026 as the date for the September 3× window; check voxi.co.uk for the allowances on sale today. Plans are 30-day rolling with price-lock messaging while you stay subscribed — always re-read voxi.co.uk/terms at purchase. European Roaming Pass rules still apply; unlimited apps can count toward data and fair-use when roaming.
Who VOXI suits in October
VOXI £10 suits you if: you are happy on Vodafone-hosted VOXI coverage, you want a true 30-day exit, social apps (Snapchat, Instagram, WhatsApp, Facebook, X, Pinterest, Messenger per VOXI’s UK list) should not burn general data, and the current £10 allowance (20GB baseline after the promo) covers maps plus light hotspot use.
VOXI £15 suits you if: YouTube / Netflix / Spotify-style apps are daily drivers and you want those in the unlimited buckets VOXI lists, with general data as overflow (25GB baseline after the promo window) — decide whether that baseline is enough or a higher-data plan suits you better.
Look elsewhere if: you need lots of general data (not social buckets), you refuse Vodafone-host coverage, or you want a tracked deal button. In that case compare the Mozillion plans on this page.
Cash vs higher-data alternatives
| Plan | Term | Price | Cash | Data story |
|---|---|---|---|---|
| VOXI £10 (September 3× offer) | Rolling | £10/mo | £120 / 12 months | 60GB + Unlimited Social in the Sep window; 20GB baseline |
| VOXI £15 (September 3× offer) | Rolling | £15/mo | £180 / 12 months | 140GB + Social/Music/Video in the Sep window; 25GB baseline |
| Mozillion Pay Monthly Plus 100GB | 24 months | £81.25 + 23 × £3.25 | £117 first 12 months; £156 / 24 months | 100GB general data, unlimited UK calls & texts |
| Mozillion Pay Monthly Plus 310GB | 24 months | £100 + 23 × £4 | £144 first 12 months; £192 / 24 months | 310GB general data, unlimited UK calls & texts |
| Mozillion 150GB | 24 months | £180 upfront | £180 / 24 months (about £7.50/mo) | 150GB general data, unlimited UK calls & texts |
Unlimited Social / Music / Video fine print
VOXI’s UK lists cover named social, music and video apps without eating general data when you are in the UK on a qualifying plan. Third-party ads, in-app browsers, and non-listed destinations still use general data. Voice or video calls inside social apps are typically not inside Unlimited Social. Keep apps updated. Roaming is a different regime — buy the European Roaming Pass rather than assuming UK unlimited buckets travel with you.
Switching steps
- Open VOXI’s SIM-only plans page and confirm today’s £10 and £15 allowances (the September 3× figures above were for that month).
- Check Vodafone/VOXI coverage for home and commute.
- Decide whether you need Unlimited Social only (£10) or Social+Music+Video (£15).
- Order or activate the rolling SIM; port with a PAC if you are keeping your number.
- Screenshot the allowance in your account.
- If VOXI’s current baseline is too small, compare Mozillion Pay Monthly Plus 100GB (about £6.50/mo equivalent over 24 months) or 310GB (about £8/mo equivalent) using the buttons on this page.
If you want a tracked deal path today, use the Mozillion buttons on this page. They are an honest high-data alternative — not the same product as VOXI’s social buckets.
How we checked this
Shop and Charges footnote re-opened 21 September 2026 (Europe/London). VOXI sells these tiles on its own site; Deal buttons on this page are live Mozillion offers (rechecked 6 October 2026). Audience: UK SIM shoppers comparing VOXI’s social-bucket plans with higher-data alternatives.
Year-1 cash at £10 is £120 and at £15 is £180 on VOXI’s rolling plans. By comparison, Mozillion Pay Monthly Plus 100GB costs £117 in the first 12 months (£81.25 upfront + 11 × £3.25) and £156 over 24 months. Recalculate on the morning you buy; this is not a permanent price promise.
Risks and honest caveats
Outside the September offer, the £10 plan’s baseline is 20GB and the £15 plan’s is 25GB unless VOXI is running a new promotion — screenshot your allowance the day you join. Hotspot still burns general data. Acceptable Use Policy applies to “unlimited” buckets.
Affiliate disclosure: SwitchSquid has no tracked VOXI product, so the deal buttons on this page are live Mozillion offers via Awin; VOXI links go to VOXI’s own shop. Always confirm allowances on the retailer checkout before you pay.
Mozillion 150GB — £180 / 24 months
- 150GB a month for 24 months — £180 paid upfront (about £7.50/mo)
- Unlimited UK calls & texts
- Confirm the £180 basket total on Mozillion before you pay
FAQ
Is VOXI 3× data still available?
VOXI advertised the September 3× offer to 30 September 2026. For October, check voxi.co.uk for the allowances on sale today, or compare the live Mozillion plans on this page.
What do I get on the £10 plan?
During the September window it included 60GB plus Unlimited Social; the baseline is 20GB. Unlimited UK calls and texts stay on the rolling SIM path.
What do I get on the £15 plan?
During the September window it included 140GB plus Unlimited Social, Music and Video; the baseline is 25GB.
Is it a contract?
No — these are 30-day rolling SIMs on VOXI’s standard path. You can leave after a month if the current allowance no longer suits you.
Why do the deal buttons go to Mozillion?
SwitchSquid has no tracked VOXI product. The buttons are live Mozillion offers via Awin — a commission link that does not change the price you pay. Buy VOXI directly on voxi.co.uk if you prefer its social buckets.
Does Unlimited Social work abroad?
The social buckets are UK-centric. Roaming needs VOXI’s European Roaming Pass and fair-use rules — read Charges before you fly.
Can I keep my number?
Yes. Text PAC to 65075 from your current SIM, then complete VOXI’s port steps when you join.
Check VOXI’s current allowances on voxi.co.uk, or compare the live Mozillion plans above.
