iPhone 18 Pro eSIM Only? The 12 Countries and Travel Setup (2026)

The iPhone 18 Pro is eSIM-only in 12 markets: Bahrain, Canada, Guam, Japan, Kuwait, Mexico, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE), the United States (US) and the US Virgin Islands. Everywhere else, including the UK, Europe and Australia, it keeps a physical SIM tray. It went on sale on 18 September 2026, and 20 more countries followed on 25 September. The list matches iPhone 17 Pro's.

An eSIM is a digital Subscriber Identity Module (SIM) built into the phone, so there is no card to swap.

Bought yours in one of those 12 markets? Travel works the way it does on any recent iPhone. You just cannot buy a plastic card at the airport. Keep your home number on one eSIM, add a data-only travel eSIM before you fly, and point cellular data at the travel line. You can skip the travel eSIM if your carrier already includes your destination in your plan at no extra cost.

What changed on 18 and 25 September

Apple announced the iPhone 18 Pro and 18 Pro Max on 9 September 2026. Pre-orders opened on 12 September, according to its press release. Sales began on 18 September in more than 65 countries and regions, and 20 more followed on 25 September. In the US it starts at $1,199, or $1,299 for the larger Pro Max. On launch day Apple marked the arrival in stores, and MobileSyrup confirmed the same-day Canadian release.

The same release names the eSIM-only markets. MacRumors compared it with last year and found the list identical to iPhone 17 Pro's, so no new country lost its card tray this year. What did change is the battery trade-off: Apple says the tray-less models use the freed space for a larger battery and two more hours of video playback.

For travellers, the useful update is quieter. Apple's travel eSIM guide and eSIM setup article both carry a 17 September 2026 publish date and now name the new phone. The setup steps further down quote both.

Which countries sell the iPhone 18 Pro without a SIM tray?

Twelve markets get the tray-less model, and Apple's model identification page adds Puerto Rico, which shares the US model. Everyone else gets a phone with one nano-SIM slot plus eSIM, and mainland China gets its own version.

Is the iPhone 18 Pro eSIM-only in the UK, Europe or Australia?

No. Apple's UK tech specs and Australian specs both list "Dual SIM (nano-SIM and eSIM)" with dual eSIM support. MacRumors reports the same for New Zealand, Singapore and South Korea. The US specs page, by contrast, reads "not compatible with physical SIM cards".

If you live in the UK or Australia, you can still run two eSIMs and leave the tray empty. You just have the fallback of a physical SIM, which buyers in the 12 eSIM-only markets do not.

What does eSIM-only mean when you travel?

A tray-less phone can only use eSIM lines abroad, so any local or travel plan you buy has to be an eSIM too. The phone holds two active eSIMs and stores eight or more, per the specs, so the usual setup is two lines: your home number and a travel data eSIM.

Apple's dual-SIM guide spells out the working rules:

• Both lines can take calls and texts, but the phone uses one cellular data network at a time. You pick which line carries data.
• Your home number stays reachable for calls, SMS and two-factor codes while the travel eSIM handles data.
• Allow Cellular Data Switching lets the phone pull data from both plans depending on coverage. Leave it off abroad if you do not want your home line carrying data without asking.

The one habit eSIM-only buyers have to drop is buying a physical SIM at the arrival hall. Apple's travel guide notes that many local carriers sell eSIMs through a Quick Response (QR) code or their app. Some ask to see your passport, so it is easier to buy before you leave.

Keeping your home line on is not free everywhere. Apple warns that with both lines on, "you might still incur roaming fees from your home eSIM". Wi-Fi calling has its own catch: one Verizon customer in Greece was billed $75 because Wi-Fi calls to Greek numbers counted as international long distance. Our Wi-Fi calling charges guide covers that trap. Canadians should also read how to avoid roaming charges in Canada before leaving the home line on.

Does the country you buy it in matter?

Yes. The country of purchase fixes the model, and the model fixes whether there is a tray. A phone bought in the US stays eSIM-only for life, even if you move to London.

A tray-less model is less limiting than it sounds. The travel guide says an eSIM-only iPhone with no carrier lock "can activate with carriers from all over the world". Three catches apply:

1. It must be free of a carrier lock. Open Settings, then General, then About. "No SIM Restrictions" next to Carrier Lock means any carrier's eSIM will install.

   If you bought the phone from a carrier, the dual-SIM guide says that carrier has to release the lock before a second carrier's plan will work.

2. Bands vary by model. If you are moving abroad rather than visiting, check the cellular band page for your model number against the country.

3. China is the exception. An eSIM from a carrier in mainland China will not work on a phone bought anywhere else, per the travel guide. A worldwide data eSIM still works there.

Say you buy the phone in Dubai and fly home to the UK. It will never take your old plastic card. Ask your home carrier to move your number to an eSIM before you switch phones. Some carriers can convert a card to an eSIM in place.

How do you set up a travel eSIM on an iPhone 18 Pro before you fly?

Install it at home over Wi-Fi, a few days before departure, and switch it on when you land. These steps follow Apple's guidance for iOS 26 and later:

1. Check the carrier lock (Settings, General, About) as above.
2. Buy a data eSIM sized for the trip. The table below prices nine destinations.
3. Scan the QR code, the square barcode your provider gives you, with the Camera app. Then tap Cellular Plan Detected. Is the code on the same phone? Tap and hold it in your email or browser and choose Add eSIM (iOS 17.4 and later).
4. Label the line "Travel" so it is easy to spot in Settings.
5. On arrival, tap Turn On Travel eSIM if the prompt appears, then choose Travel eSIM and Current eSIM. The travel eSIM then carries data. Without the prompt, go to Settings, Cellular, Cellular Data and pick the travel line.
6. Turn off Data Roaming on your home line. The cellular data article recommends this to avoid roaming charges.
7. Coming home: with iOS 26 and later, the iPhone turns the travel eSIM off and your home line back on automatically in supported countries. If it does not, turn your primary line back on in Settings, Cellular.

If the profile fails to install or shows No Service on landing, our iPhone eSIM troubleshooting guide walks through the usual causes.

What a travel data eSIM costs from an eSIM-only market

The table lists the cheapest Lotsotravel fixed-data plans for nine destinations. We read them from our live catalog on 25 September 2026. Prices are what you pay through the link on this page.

The US, Canada and Mexico are each sold as separate single-country plans; no one eSIM covers all three. Gulf owners heading to the relocated Bahrain Grand Prix at Sepang can use the Malaysia plan or the Asia-Pacific one.

What about the iPhone Duo?

The iPhone Duo is eSIM-only in every country, China included, so everything above applies to it wherever you buy one. Its press release opens pre-orders on 16 October 2026. Sales start on 23 October in more than 70 countries and regions, and 28 more follow a week later. It starts at $1,999 in the US.

The Duo specs page lists the same eSIM capacity: two active, eight or more stored. The setup steps above carry over unchanged. The one difference: a buyer in the UK or Australia gets no card tray either, so their fallback disappears too.

If your trip leaves before 23 October, or you cannot get one at launch, none of this changes what you do with the phone you already have.

What this guide does not cover

We have not tested either phone abroad, so nothing here speaks to signal, speed or battery life on foreign networks. The battery figures are Apple's own. We do not price your home carrier's roaming passes in this post, and we do not check your model's bands for any specific country. The device compatibility guide covers older iPhones and Android phones.

Lotsotravel plans are data-only. They do not give you a local phone number, so calls and texts to local numbers go through apps or your home line.

Where Lotsotravel fits

Lotsotravel is an independent travel eSIM provider covering about 190 destinations, with plans from $4.95 USD. You buy on the website (there is no app), you get an email when your QR code is ready, and you scan it from the website onto the iPhone.
