Next update: when Mozillion removes sim-detail/24346 or reprints the £96 / 30GB PAYG flash.
By: Switch Editorial Team, Switch Squid Ltd
As of 21 September 2026, Mozillion’s own shop still sells a 30GB PAYG SIM at £96 upfront for 24 months — equivalent to £4 a month — with unlimited UK calls and texts, no credit check, no mid-contract price rises, uncapped 5G, hotspot, Wi‑Fi calling and EU roaming in 41 destinations (7.5GB fair-use data abroad on this tier). That cash beat every rolling 30GB SIM we opened this morning once you annualise the prepaid lock: twelve months of service is already paid inside the £96, and months 13–24 cost £0 more if you keep using the allowance.
I am Switch. This urgency guide answers Mozillion £4 30GB SIM deal UK September 2026 from mozillion.com/sim-detail/24346 verified live today — not a comparison-site exclusive and not the older Mozillion PAYM Plus 30GB tiles at different upfront maths. Soft context on the SIM only deals hub is fine; Get deal buttons use Awin affiliate 911601 only.
What you actually buy for £96
Mozillion labels this as a pay-as-you-go SIM with a 24-month duration. You pay £96 once. The retailer equates that to £4 a month. Inclusive allowances on the live product page today:
- Data: 30GB every month for 24 months
- Calls & texts: unlimited UK
- Credit check: none for this SIM-only path
- Price rises: no mid-contract rises on the published copy
- Network: Mozillion on the UK’s “Best Network” branding (EE host — confirm coverage for your postcode on Mozillion’s checker)
- Speeds: uncapped 5G / 4G with hotspot and Wi‑Fi calling supported
- Number: keep your number (PAC / STAC as usual)
- EU roaming: 41 destinations listed; 30GB UK plan maps to 7.5GB roaming data fair-use
That is a prepaid-style lock, not a classic rolling Flex bill. If you hate annual April rises and you know you will use a phone SIM for two years, the £96 flash is the cash story. If you might cancel in month three, model the sunk £96 against a £7 rolling 30GB rival before you click.
Cash table vs common 30GB rivals (21 Sep 2026)
We rank by honest 12-month cash where the retailer publishes a clear monthly price, and we show Mozillion’s prepaid lock as total cash already paid.
| Plan (opened 21 Sep 2026) | Term | Headline | 12-month cash | 24-month cash | Notes |
|---|---|---|---|---|---|
| Mozillion 30GB PAYG (sim-detail/24346) | 24 months prepaid | £96 upfront (= £4/mo) | £96 (already covers 12m) | £96 | Unlimited calls/texts, no credit check, price lock, 5G, EU 7.5GB FUP |
| Talkmobile Flex 30GB | 30-day rolling | ~£6.95/mo | ~£83.40 | ~£166.80 | Vodafone masts; confirm live Flex price on talkmobile.co.uk |
| iD Mobile 30GB 1-month | 1-month | ~£7.00/mo | ~£84.00 | ~£168.00 | Three masts; no April rise language on iD SIM copy |
| spusu 30 | Rolling | ~£9.90/mo | ~£118.80 | ~£237.60 | Uncapped 5G on Three; higher cash |
| VOXI social 30GB tiers | Rolling | from ~£10/mo | ~£120+ | ~£240+ | Social extras; not a like-for-like vanilla 30GB |
How to read the table: Talkmobile and iD can win Year-1 cash if you stay rolling and never need the second year prepaid. Mozillion wins the locked two-year cash race at £96 flat — and it already beats Year-1 rivals on a pure “money leaving your account in the first twelve months” view only if you treat the whole £96 as Year-1 spend (you do). The strategic win is months 13–24 at £0 incremental. That is why this page is an urgency guide, not a rolling Flex clone.

Who this £4 flash is for
Buy it if: you already own an unlocked handset, you use roughly 10–30GB a month, you want unlimited UK calls/texts without a credit search, you travel to listed EU destinations a few times a year within the 7.5GB roaming cap, and you are happy to pay £96 today rather than drip £7 monthly.
Skip it if: you need true unlimited UK data, you hotspot a laptop all day (30GB evaporates), you may leave the UK network in under six months, or you prefer a 30-day exit with zero sunk prepaid. In those cases open our 30GB SIM only deals UK table for rolling cash leads instead of forcing this flash.
EE host, 5G and the “Best Network” claim
Mozillion’s retail copy leans hard on UK Best Network awards and uncapped 5G. In practice you are buying Mozillion’s airtime on the EE radio host. Check EE/Mozillion coverage for your home and commute postcodes before you celebrate the £4 maths. Indoor basement flats and thick-walled Victorian terraces still need a signal check — price lock does not invent bars.
Uncapped 5G means Mozillion is not advertising a low Mbps throttle on this SIM the way some value MVNOs do. Congestion, handset band support and mast load still decide your real speed. For 4K hotspot evenings, 30GB is the constraint long before the radio is.
No credit check, price lock and PAC
No credit check is the conversion hook for rejected contract buyers and for anyone who simply does not want a soft search. Price-lock language matches the prepaid £96 — there is no April CPI+ ratchet on this SKU in the copy we opened. Porting in: request a PAC from your losing provider, complete Mozillion’s checkout, and keep both SIMs until the port SMS confirms. Do not cancel the old line early in a way that creates a dead-air gap.
After 24 months, Mozillion’s generic plan explainer language points you toward choosing a fresh SIM-only plan or a handset bundle. Budget a replacement airtime SKU before month 24 so you are not caught on a default you did not price.
EU roaming fine print (read this before sunny holidays)
Mozillion lists 41 roaming destinations including Spain, France, Italy, Germany, Ireland, Greece and more. Inclusive roaming covers local landline and mobile calls within the same country. Data fair-use on the 30GB UK plan is 7.5GB abroad — not your full UK 30GB. Heavy streamers abroad should add a travel eSIM or buy a Mozillion top-up path rather than burning the FUP on hotel Wi‑Fi failures.
Switzerland, Norway and several overseas departments appear on Mozillion’s destination list for this product family — always re-read the live sim-detail page the week you fly, because roaming grids move.
How this differs from Mozillion’s cheaper-looking hub tiles
SwitchSquid’s live SIM tables sometimes sort Mozillion PAYM Plus 1GB / 3GB / 10GB / 30GB rows by low monthly equivalents with different upfront totals (for example older 30GB rows near £2.75/mo with ~£68.75 upfront). Those are not this flash. sim-detail/24346 is the £96 / 30GB / 24-month PAYG object of this URL. Do not click a £2.75 card expecting 30GB at £4 maths — read the data column.
Our Nest deal-card below is wired only to product 656004, which deep-links the verified Awin cread for 24346 under affiliate 911601.
Switching steps (15-minute path)
- Confirm EE/Mozillion coverage for home + work.
- Open the live Mozillion 24346 page via our affiliate CTA (aff 911601).
- Choose eSIM or physical SIM; keep your number if you need it.
- Pay the £96; screenshot order confirmation and allowance dates.
- Insert / install the SIM; send a test text; enable Wi‑Fi calling if indoor signal is weak.
- Set a calendar reminder at month 22 to price the next airtime plan.
Risks and honest caveats
Flash SIMs disappear. If 24346 404s or the £96 tile changes, this page’s lead sentence is wrong until we republish — that is why the next-update line sits at the top. Prepaid £96 is non-trivial if your phone habits collapse to Wi‑Fi-only. EU 7.5GB is enough for maps + messaging + light social, not a fortnight of hotel 4K. Hotspot on a work laptop will chew 30GB fast during a single cloud backup.
