When we checked on 27 October 2026, Mozillion’s 30GB Pay Monthly Plus SIM was £68.75 upfront, then 23 monthly payments of £2.75. That is £132 over 24 months, or about £5.50 a month on average. It includes unlimited UK calls and texts, EU roaming in 41 countries, hotspot use and Wi-Fi calling, and Mozillion says there is no credit check and no mid-contract price rise. The catch is the large first payment and the two-year term.

How Pay Monthly Plus works
You pay roughly half of the 24-month plan at the start, together with your first month, and the rest over the following 23 months. For 30GB that is £68.75 upfront and £2.75 a month after that. The price is fixed for the term, but you are committing to the full 24 months.
Mozillion sells other allowances on the same terms. When we checked on 27 October 2026: 10GB was £62.50 then 23 × £2.50 (£120 in total), 100GB was £81.25 then 23 × £3.25 (£156 in total) and 310GB was £100 then 23 × £4 (£192 in total).
Pay Monthly Plus or a normal monthly 30GB plan?
Mozillion 30GB plan (when we checked on 27 October 2026) | Term | What you pay | Total over 24 months |
|---|---|---|---|
Pay Monthly Plus | 24 months | £68.75 upfront, then £2.75 a month | £132 |
24-month plan | 24 months | £7 a month | £168 (£7 × 24) |
12-month plan | 12 months | £7.50 a month | £90 over 12 months (£7.50 × 12) |
1-month plan | Rolling | £7.90 a month | £189.60 if kept for 24 months (£7.90 × 24) |
Pay Monthly Plus has the lowest two-year total of the four, £36 less than the standard 24-month plan. The 1-month plan costs the most over two years, but you can leave or change allowance with a month’s notice, which matters if your plans might change.
Mozillion 30GB 1-month plan — £7.90 a month, leave any month
- The same 30GB allowance with unlimited UK calls and texts on a 1-month rolling plan, when we checked on 27 October 2026
- No large first payment: £7.90 a month, or £94.80 over 12 months (£7.90 × 12) if the price stays the same
- Main limitation: over two years it costs more than Pay Monthly Plus. Confirm 30GB and £7.90 on Mozillion’s page before you pay
Who should consider it?
It suits someone who wants 30GB with unlimited calls and texts for two years and can comfortably pay £68.75 at the start (the upfront payment when we checked on 27 October 2026). 30GB covers maps, messaging, music and some video for most people. Ofcom’s Communications Market Report 2026 puts average use at about 12GB a month, so check your phone’s data screen for the last few months before you commit.
If you may want to leave early, the 1-month plan is the safer choice. If you would rather not pay a lump sum but still want two years, the standard 24-month plan keeps the first payment small.
Coverage, roaming and switching checks
Coverage varies by postcode, so check coverage for home, work and anywhere you travel often before you order. EU roaming covers 41 countries on Mozillion’s plan pages; check the fair use allowance for your plan before you travel.
To keep your number, text PAC to 65075 from your current phone and give the code to Mozillion when you order. Our PAC code guide explains the steps. Check that your phone is unlocked and whether you need a physical SIM or an eSIM.
