UK iPhone 17 Pro/Pro Max – eSIM-Only Availability and Battery Differences

I’m planning to upgrade this year due to some of the features, although I do have some questions about the different configurations.


In the US, all iPhone 17 models are eSIM-only, which reportedly allows for a larger battery. Granted this is the first year they've audibly announced this.


I wanted to confirm whether the same is true in the UK, or if the other models besides the Air still include a physical SIM tray. If there are both SIM-tray and eSIM-only variants available, I would also like to understand whether this affects the quoted battery life for each model.


My main goal is to ensure I choose a model with the maximum battery capacity. If no eSIM-only option is available in the UK, it would feel a bit disappointing to pay the same price for a slightly smaller battery, even if the difference is small. Any clarification you could provide would be greatly appreciated.

iPhone 17 units originally sold in the UK have a physical SIM card slot and about an hour less battery capacity than the USA ones. There isn't an option to get them without the slot.

Well I was going to go for the I phone 17 pro max but as its sim only and you cannot buy e sim in the uk I’m not upgrading what’s the point of paying the same price for a smaller inferior battery it’s near enough the same as last gen very annoying Apple.

You are misinformed. A UK variant iPhone 17 won't be SIM only. It WILL have a SIM Slot, but it will also have the ability to use eSim as well. And the comment that you'd be getting an inferior battery seems a bit extreme. It will be slightly smaller as a physical SIM tray does take some space away, but the battery could hardly be considered inferior. And really, do people consider only the battery size as a reason to upgrade? What about ALL the other terrific features on the new iPhones?


All four major UK mobile network operators — EE, O2, Three, and Vodafone, fully support eSIM functionality for compatible devices. In addition to these, several other providers offer eSIMs, including Giffgaff, Honest Mobile, iD Mobile, Lyca Mobile, Sky Mobile, Spusu, Tesco Mobile, and VOXI.

He’s not misinformed at all, the EU/UK Pro models have a smaller battery due to the SIM tray, which means ~2 hours less battery life. Since the iPhone Air is eSIM-only worldwide (including the UK), it makes no sense. We pay the same as US buyers, have to deal extra bulk of the Pro but without the full benefits .and that’s a valid complaint.

A comprehensive analysis has revealed that my initial assumptions and knowledge were entirely erroneous.


The country-specific specifications are provided below.


These specifications indicate that eSIM-only models (including those in the UAE) of the iPhone 17 Pro and Pro Max have a larger battery capacity (Size not clear) than those with a physical SIM tray.


Both the USA and UAE versions: iPhone 17 and iPhone Air models are activated with an eSIM and do not support a physical SIM. Using an eSIM requires a carrier that supports eSIM and a compatible wireless service plan. See your carrier for details. To learn more, visit apple.com/ae/esim.

After reading through this whole thread, here’s my perspective:


I completely understand why some European customers still prefer having a SIM tray, even though I personally would go for eSIM. Europe is clearly in a transition phase, and within a couple of years, I’m confident that eSIM will become the standard. Here in Ireland, several providers already offer eSIM alongside traditional SIM cards, so it wouldn’t surprise me if Apple switches to eSIM-only models across Europe very soon.


That said, my only suggestion (rather than complaint) is that Apple should have given European customers the choice between the two variants: eSIM-only or SIM + eSIM. Technically, eSIM-only iPhones sold in the U.S. or other regions already meet all global mobile standards and can be used perfectly well in Europe.


When you’re spending over €1,000 on a device, it feels fair to expect the option to choose — especially when the eSIM-only models come with a noticeably larger battery. In Europe, we’re often paying higher prices (since EUR and GBP pricing is usually on par with USD) but receiving fewer options. The battery difference between models — around 5–10%, depending on whether it’s the iPhone 17 Pro or Pro Max — is not negligible.


To put it simply: a U.S. iPhone 17 Pro Max (eSIM-only) with one year of use and 95% battery health would still deliver roughly the same endurance as a brand-new European model with a SIM tray. That’s a significant difference in day-to-day use.


At the moment, the only way for me in Ireland to get an eSIM-only version is to import one from an eSIM-only market and then pay an additional 23% VAT — which feels quite unfair during this transition phase. That’s why I believe Apple should have given European customers the choice.


As for me, I was lucky enough to have a friend in Saudi Arabia bring one over. In the end, I paid about €150 less (around 10% cheaper) and got a phone with a 5% larger battery. A win-win — but it really shouldn’t have to be this complicated.

If you had actually read my post you would realise that I know we have e sim I’m saying I would like an i phone with eSIM only so I could purchase the 5088 mah battery not the 4823 mah which comes with the uk version of the iPhone because you have to have a sim tray.

If you read the answers you would know that you cannot buy it in UK, but if it is what you want then suggest it https://apple.com/feedback

Hello,

I was also planning to upgrade from a 16 PM to a 17 PM UK model. Only to find out the battery size is not the same as the US version and other selected countries due to being an ESIM only model.

Yet the IPhone Air is ESIM only and can be purchased in the UK.

Can someone please explain this?


The iPhone 17 Air, which is eSim-only worldwide, is much thinner than the iPhone 17 Pro and 17 Pro Max. Getting rid of the eSim tray may have been part of what allowed for the thinness.


The iPhone 17 Air also has significantly smaller battery runtime than the iPhone 17 Pro and 17 Pro Max, unless you purchase and use the optional external MagSafe battery pack.

I cannot see a number or brackets here. Can you please post a screenshot of what you see regarding a number and brackets on your screen?

I think they were asking Niel and this is likely what they're referring too:

I'm not interested in a physical sim tray, that I will not use, and that is going to make the battery capacity of my iPhone 17 pro lower. If I buy the iPhone 17 pro, I don't want to pay a premium price for an outdated technology (physical SIM card), which is not going to be useful to me, and have a lower battery capacity, while some others can get the full premium experience in Canada or Japan, or.... I'm from France. Apple should offer the possibility to buy the eSIM-only iPhone 17 pro to Europeans. I'm disappointed. I need to renew my device. But maybe the iPhone isn't the smartphone I need after all, as it doesn't satisfy my European needs.


Do as you please – but the battery runtime on the European versions of the iPhone 17 Pro and iPhone 17 Pro Max looks pretty good to me.


It really sounds to me like this is a "d**mned if you do, d**mned if you don't" situation for Apple. They made U.S. phones eSim-only and there were howls of protest by people who swore that they needed to use physical SIMs – and that they would not buy iPhones without physical SIM trays, because they supposedly weren't as good as the ones sold elsewhere.


Now people in this thread are howling about iPhones with physical SIM trays because the trays are there.


I suppose that Apple could have simply released the U.S. phones with the same-sized batteries as the European ones, not letting on that the removal of the SIM tray would have allowed for a slightly larger battery. But instead, they made use of the tiny bit of extra space in the eSIM-only models … and no good deed went unpunished.

what is going on in this thread, I just see people repeating the same few ideas in different ways going in circles, I guess you guys just needs a place to let out your complaints? Or people who can’t read at all and misunderstand what each other is saying lmfao.

The battery difference between the eSIM only and SIM tray is 100% not negligible, 2 hrs of battery life is significantly different, not like 20 minutes.

Instead of complaining, why not look for solutions? I’ve always needed a physical SIM tray, while living in the states, I’ve been easily buying iPhones from other countries and shipped to the states. Jesus people. It’s not that complicated. Just buy it from a country where it meets your requirements, and get it shipped back to you. We’re all adults, google is free, it’s not that hard of a process.
