What we know, what we suspect
Three things to weigh up before pre-ordering
Apple has not announced the iPhone 18 Pro Max. Everything below is based on consistent supply-chain reporting (Kuo, Gurman, DigiTimes) and how the iPhone 17 Pro Max was priced in September 2025. We will rewrite this section the moment Apple publishes official specs.
Point 1 . Price likely up
Expect about £50 more than the 17 Pro Max
The iPhone 17 Pro Max started at £1,199 in September 2025. The 18 Pro Max is expected to push the entry storage to 256GB by default and to absorb roughly 4 % of UK inflation. That is how we land at the £1,249 entry projection. The 1TB top tier is likely to clear £1,800 for the first time on a Pro Max.
Point 2 . Carriers undercut on day one
The cheapest day-one deal is rarely from Apple
On the iPhone 17 Pro Max launch (Sept 2025), the cheapest 24-month total in the UK was Tesco Mobile's Anytime Upgrade at around £1,849, undercutting the Apple Store outright by £120 when you add a basic SIM-only plan. We expect a near-identical pattern this year. Tesco Mobile, Sky Mobile and Three Advanced are the names to watch on day one.
Point 3 . The 36-month trap
A low monthly price often hides a longer lock-in
O2 Custom Plans and Tesco Mobile Anytime Upgrade can drop the headline monthly bill below £75, which looks brilliant. The catch is that the device split is spread over 36 months instead of 24. You will still be paying for this iPhone in September 2029, when the iPhone 21 Pro Max is on sale. Always rank deals by the total column in our grid, never by the monthly figure alone.

Reading the table. The 24-month total assumes you keep the plan for its full term. For 36-month plans we still show the 24-month figure so the columns are comparable, then add the remaining 12 months of airtime in the small print of each carrier's page. Apple Store outright has no airtime - assume around £15 per month for a SIM-only plan on top.
Prices are pre-launch projections based on the iPhone 17 Pro Max September 2025 carrier launches and 2026 UK CPI. Refreshed on Apple's announcement day.
Interactive deal finder
Which iPhone 18 Pro Max deal fits you?
Four quick questions. We pick the offer from our grid that matches your priorities.
Some deals ask for £30 to £100 on day one. Sky Mobile and the Apple Klarna route ask for £0.
A 36-month split lowers the monthly bill but extends your contract past two more iPhone launches.
A heavy streamer needs unlimited. Most users use under 30GB and overpay on unlimited plans.
If yes, buying the iPhone outright from Apple plus keeping your SIM is almost always the cheapest path.

If you go contract
How to read an iPhone 18 Pro Max contract without getting fleeced
- 1 Find the term length first. EE, Vodafone, Three and iD Mobile sell 24-month deals. O2 and Tesco Mobile increasingly push 36-month splits. A lower monthly figure on a 36-month plan is almost always more expensive over its life.
- 2 Add the upfront cost to the total. A £0 upfront deal often hides £5 to £10 extra in the monthly. Multiply the monthly by the number of months, add the upfront, then compare. That is the column we rank by in the table above.
- 3 Watch for the April price rise. EE, Vodafone, Three and O2 all apply CPI + 3.9 % to the airtime portion every April. On a £60 monthly airtime, that is roughly £3 to £5 more per month from year two. Tesco Mobile, Sky Mobile and iD Mobile do not apply mid-contract rises.
- 4 Check the included perks against what you would actually use. EE bundles Apple TV+ and Netflix. O2 gives you Disney+ on Volt plans. If you already pay for those services, the bundle is a genuine saving. If you do not, you are paying for things you do not want.
- 5 Confirm the phone is unlocked or how to unlock it. All UK carriers ship iPhones unlocked since December 2021, but very old SIM-locked devices still circulate on second-hand markets. New from a UK carrier should be unlocked by default. Ask before paying.
Insider angle
Why Pro Max deals look so different from regular iPhone deals
On the standard iPhone 18 (when it lands), most UK carriers will compete almost entirely on the monthly airtime price. The hardware cost is similar, the data buckets are similar, the perks are similar. You can flip through ten quotes and find the differences in the small print.
The Pro Max is different. The phone itself costs £1,249 to £1,849, which is more than what most carriers earn from the airtime over the whole contract. So this is the model they push hard with longer terms, deeper subsidies and bundled streaming. The headline monthly figures look almost too good. The catch is always the term length or a mid-contract rise.
The single most reliable trick: rank by total cost over 24 months and treat the monthly figure as a distraction. The retailer with the best advertising rarely has the cheapest 24-month total. In our grid above, the Apple Store outright sits at the top once you add a basic SIM-only plan, then iD Mobile and Tesco Mobile fight for second place.
If you want one rule of thumb
Buy the phone outright from Apple via Klarna (0 % APR, 24 months) and pair it with a SIM-only plan from Smarty, iD Mobile or Tesco Mobile. Total cost lands around £1,609 and you walk away with an unlocked phone after two years. No carrier contract beats that on a Pro Max, unless you genuinely need EE-grade coverage.
iPhone 18 Pro Max FAQs
The Selectra expert answers your questions
Apple has not announced the iPhone 18 Pro Max. Based on every iPhone since 2012, the UK on-sale date will be the second or third Friday of September 2026. Pre-orders open the Friday before, so expect to lock in an order around the first week of September 2026. We will refresh this section the day Apple confirms.
Expect a £1,249 starting RRP for the 256GB and roughly £1,849 for the 1TB top tier. That is about £50 more than the iPhone 17 Pro Max charged in September 2025, reflecting a likely jump in the base storage tier and 2026 UK inflation. Carrier prices spread the cost over 24 or 36 months. See the table above for the full list.
On the iPhone 17 Pro Max launch in September 2025, the cheapest 24-month total contract was iD Mobile via Currys. We expect the same pattern for the 18 Pro Max. For absolute lowest total spend including airtime, buying outright from Apple via Klarna and pairing with a £15 SIM-only plan usually beats every carrier contract over two years.
If you need a phone today, the iPhone 17 Pro Max drops in price by £100 to £150 the day the 18 Pro Max launches, and gets discounted again in the December sales. If you can wait until October 2026, either grab the new 18 Pro Max or buy a discounted 17 Pro Max. There is rarely a good reason to pay full RRP for a Pro Max in July or August.
For most buyers, wait two weeks after launch. Apple's Pro Max launch firmware almost always ships with one or two early-stage bugs that get patched in the first 14 days. The exception is if you need it for September fashion week or a work trip - then pre-order from the Apple Store so you can return within 14 days under UK consumer law if you change your mind.
Yes. All UK 5G plans (EE, Vodafone, O2, Three, plus MVNOs like Sky Mobile, Tesco Mobile and iD Mobile) will work with the iPhone 18 Pro Max from day one. The phone uses eSIM as standard in the UK - the physical SIM tray was dropped on the 17 Pro Max and the 18 will follow suit. Your carrier can transfer an existing SIM plan to an eSIM in a few minutes.
