Mozillion is selling the iPhone 18 Pro and 18 Pro Max on 24-month contracts with no mid-contract price rises — a real difference in a market where most networks raise your bill every April.
But a fixed price is not the same as a good price. So we worked out the total cost across the full 24 months on every data tier, then checked it against buying the handset from Apple and adding a SIM-only plan instead.
This is where the biggest difference in total cost appears — and it turns on something most people never think about: how much mobile data you actually use.
The short version
- Mozillion iPhone 18 Pro, 256GB: from £59.13 a month plus £29 upfront — £1,448.12 over 24 months on the 30GB plan
- Mozillion iPhone 18 Pro Max, 256GB: from £63.88 a month plus £29 upfront — £1,562.12 over 24 months on the 10GB plan
- On the 10GB plans, buying the handset from Apple and adding a SIM-only plan worked out cheaper — by £86 on the Pro and £72 on the Pro Max
- On 100GB and unlimited, the bundled contract came out cheaper — by up to £142
- Odd but true: on the iPhone 18 Pro, the 10GB plan costs more per month than the 30GB plan
- Compare Mozillion’s SIM-free price against Apple’s before buying outright — when we checked there was £200 between them on the Pro Max
Mozillion iPhone 18 Pro contract prices
All figures are 256GB, 24-month contract, £29 upfront, on the EE network with unlimited calls and texts.
| Data | Monthly | Total over 24 months |
|---|---|---|
| 30GB | £59.13 | £1,448.12 |
| 10GB | £60.29 | £1,475.96 |
| 100GB | £61.29 | £1,499.96 |
| Unlimited | £66.79 | £1,631.96 |
Mozillion iPhone 18 Pro Max contract prices
| Data | Monthly | Total over 24 months |
|---|---|---|
| 10GB | £63.88 | £1,562.12 |
| 30GB | £64.38 | £1,574.12 |
| 100GB | £64.88 | £1,586.12 |
| Unlimited | £72.88 | £1,778.12 |
Here the tiers rise in the order you would expect, and the steps are tiny: 10GB to 100GB costs £1 a month, or £24 across the whole contract. Unlimited costs another £8 a month, which is £192 over two years.
That compression matters, and it is the key to the next section.

Both models run the A20 Pro chipset with three 48MP cameras, and support nano-SIM and eSIM. The Pro has a 6.3in display, the Pro Max 6.9in. Beyond size and battery life, you are choosing between them on price rather than capability.
Contract, or buy the phone and add a SIM?
Mozillion sells SIM-only plans separately, with no credit check and the same fixed-price policy. So you can buy the handset outright from Apple and add a SIM instead of taking a bundled contract.
Apple’s own starting prices are £1,199 for the iPhone 18 Pro and £1,299 for the Pro Max, both 256GB. Here is how the two routes compared on the figures we checked.
| Data | Mozillion contract | Apple + SIM-only | Cheaper on these figures |
|---|---|---|---|
| 10GB | £1,475.96 | £1,389.80 | Outright, by £86 |
| 30GB | £1,448.12 | £1,461.80 | Contract, by £14 |
| 100GB | £1,499.96 | £1,533.80 | Contract, by £34 |
| Unlimited | £1,631.96 | £1,773.80 | Contract, by £142 |
| Data | Mozillion contract | Apple + SIM-only | Cheaper on these figures |
|---|---|---|---|
| 10GB | £1,562.12 | £1,489.80 | Outright, by £72 |
| 30GB | £1,574.12 | £1,561.80 | Outright, by £12 |
| 100GB | £1,586.12 | £1,633.80 | Contract, by £48 |
| Unlimited | £1,778.12 | £1,873.80 | Contract, by £96 |
At the lower data tiers, Apple plus SIM-only is cheaper. At the higher tiers the bundled contract is cheaper. The crossover falls at 30GB on the Pro and somewhere between 30GB and 100GB on the Pro Max.
Another way to see it: at 100GB the handset works out at about £1,165 inside the iPhone 18 Pro contract, against Apple’s £1,199 — and about £1,251 inside the Pro Max contract, against Apple’s £1,299. At those tiers you are effectively getting the phone slightly below Apple’s price, spread across 24 months.
Bear in mind that “cheaper” here means cheaper in pounds over 24 months, and nothing else. Buying outright also gives you ownership from day one, no credit agreement, and the freedom to change airtime provider whenever you like. Those may matter more to you than the difference in total.
Mozillion SIM-only prices
| Data | 24-month | 12-month |
|---|---|---|
| 3GB | £4.50 | £4.70 |
| 10GB | £7.95 | £8.50 |
| 30GB | £10.95 | £11.50 |
| 80GB | £12.95 | £13.50 |
| 100GB | £13.95 | £14.50 |
| Unlimited | £23.95 | £24.50 |
The 12-month plans cost between 20p and 55p a month more. The shorter term lets you reassess sooner, though it also means your price is only fixed for a year rather than two.
If you are buying the handset outright
Compare Mozillion’s SIM-free price against Apple’s before ordering. When we checked, Mozillion listed the iPhone 18 Pro Max 256GB at £1,499 while Apple’s own starting price for the same model was £1,299 — a £200 difference on identical hardware.
Prices move, so check both. But it is a useful reminder that a retailer can be competitive on contracts and SIM-only while being expensive on outright sales. Check each separately rather than assuming one follows the other.
What the plans include
Unlimited calls and texts, 4G and 5G with a fair-use policy that allows throttling above 500GB a month, WiFi calling, hotspot tethering, spend capping so you cannot run up a surprise bill, and roaming across 41 European countries with up to 25% of your monthly allowance usable abroad.
Mozillion runs on EE’s network, which it promotes as the UK’s best network based on industry awards — check coverage at your own address rather than taking that at face value. Handset contracts are 24-month credit agreements arranged through Affirm, with Mozillion acting as credit broker rather than lender, so they involve a credit check. SIM-only plans do not.
There is also a scheme called Kill Your Bill, where you buy gift cards through their app for shops you were using anyway and a reward is credited against your phone bill. Mozillion states that most users reach a zero bill within their first month. We have not tested that, and how much it reduces your bill depends entirely on how much you spend and where, so treat it as a possible extra rather than a reason to choose the plan.
Which route suits you
Three situations, and the arithmetic points somewhere different in each.
You have the cash and use little data
Buy the handset from Apple and add a Mozillion SIM-only plan. On the figures we checked, the Pro Max at 10GB came to £1,489.80 all in over two years, around £72 less than the equivalent contract, and the Pro came to £1,389.80, around £86 less. You also own the phone outright, avoid a credit agreement, and can switch airtime whenever you like.
You have the cash but want a lot of data
Run both numbers before deciding. At 100GB the contract came out £34 cheaper on the Pro and £48 cheaper on the Pro Max, because the bundled data is priced so low. On the unlimited tiers the gap widened to £142 and £96. At those levels the contract is clearly the cheaper route in pounds, though you are trading ownership and flexibility for it.
You do not have the full handset price spare
The contract spreads the cost over 24 months, and the fixed-price policy means the payment you agree is the payment you make for the full term. That is worth something in a market where most contracts rise annually.
Or consider last year’s model
Worth thirty seconds before you commit. Mozillion also lists the iPhone 17 Pro Max and 17 Pro at lower monthly prices than the 18 series, for hardware one generation behind. If the newest chipset will not change how you actually use your phone, check both before deciding.
How to check any phone deal yourself
This is the part worth keeping, whoever you buy from. Four steps, five minutes, and it works on every contract you will ever be offered.
- Work out the total. Monthly payment times the number of months, plus anything upfront. That single number is the only fair way to compare two deals.
- Add the price rises. If a contract raises prices annually, work out what that adds across the term. A £2.50 monthly increase applied each April adds roughly £55 over 24 months; a percentage-based rise on an expensive plan can add considerably more. Check the specific terms of the contract in front of you.
- Split the phone from the airtime. Look up the handset price from the manufacturer, then a SIM-only plan with the same data, and add them together. Compare that against the contract total. If the contract is higher, you now know exactly what the convenience of spreading the cost is costing you.
- Check your real data use. Your phone settings or your current bill will tell you. Contract data tiers are often priced so the largest allowance looks almost free, which makes it easy to pay for data you never use.
Check the current prices
Prices and availability shift, particularly around a launch. These links go to Mozillion’s contract pages, where you can choose storage, colour and data tier and see the live monthly figure for yourself.
Affiliate links — we may earn a commission if you buy. Our advice stands either way: multiply the monthly by the term, add the upfront, and compare that total against the handset price plus a SIM-only plan before you commit.
Frequently asked questions
Is it cheaper to buy the phone outright?
It depends on how much data you need. On the prices we checked, buying the Pro Max from Apple at £1,299 and adding a £7.95 SIM-only plan came to £1,489.80 over two years, around £72 less than the 10GB contract. At 100GB the contract came out £48 cheaper, and on unlimited £96 cheaper, because bundled data is priced very low. Work out both figures for your own usage and current prices.
Does Mozillion really not raise prices mid-contract?
Mozillion states that payments are fixed with no mid-contract increases, and this applies to both handset contracts and SIM-only plans. That is a real difference from most UK networks, which raise bills each April. Confirm it in the plan terms before you sign, as with any contract commitment.
How much do annual price rises actually cost?
It depends on the contract. A flat increase of £2.50 a month applied each April adds roughly £55 across a 24-month term that starts in autumn. Percentage-based increases on a higher monthly payment can add considerably more. Check the specific wording of any contract you are offered.
Which network does Mozillion use?
Mozillion runs on EE’s network, so coverage matches EE rather than being separate. Check coverage at your own address with their coverage checker before ordering.
Do SIM-only plans need a credit check?
No. SIM-only plans have no credit check. Handset contracts do, because they are 24-month credit agreements arranged through Affirm, with Mozillion acting as credit broker rather than lender.
How much data do I actually need?
Check your current usage in your phone settings or on your bill rather than guessing. On the SIM-only prices we saw, 10GB was £7.95 and 100GB was £13.95, so the larger tier costs £144 more across two years — worth it if you use it, wasted if you do not. On contract the same step costs as little as £24, which is why the bundle wins at the top tiers.
How much storage should I get?
Check how much you are using on your current phone, in Settings. Larger storage adds several hundred pounds across a 24-month term, so it is worth knowing whether you need it before paying for it.
What should I do when the contract ends?
Move to a SIM-only plan. You own the phone at that point, so staying on contract pricing means paying for a handset you already own. Set a calendar reminder — this is one of the most common ways people quietly lose money on mobile contracts.
The verdict
Mozillion’s fixed-price policy is real and unusual, and worth having in a market where most contracts rise every April. The plans themselves are well specified: EE coverage, generous data, spend capping and proper European roaming.
The decision that moves the most money is contract versus outright, and it turns on your data use rather than your bank balance. On the figures we checked, on the 10GB tiers buying the handset from Apple and adding a cheap SIM-only plan came out £72 to £86 cheaper. At 100GB and above the bundled contract was cheaper, by £34 to £142 depending on model and tier. And if you are buying outright, compare Mozillion’s SIM-free price against Apple’s first — when we looked there was £200 between them.
Whatever you choose, do the arithmetic on the day you buy. Multiply the monthly by the term, add the upfront, and compare that total. Prices on a launch product move quickly, and the total is the only number that tells you the truth about a phone deal.
Sources and method
Contract prices, SIM-only prices, SIM-free prices, plan inclusions, roaming terms, credit terms and delivery dates were taken from Mozillion’s own product and plan pages on 17 September 2026. Apple SIM-free prices as published for the UK launch, September 2026. All 24-month totals are our own calculations from those figures. Mozillion is a launch-week retailer on a newly released handset and its prices may have changed since we checked — the figures here are a dated snapshot, not a live price feed, and you should confirm current prices on the retailer’s own pages before ordering.
