eSIM News: The Changes That Actually Affect Travelers in 2026

Most eSIM industry news is written for the industry: shipment forecasts, IoT connection counts, specification numbers. Very little of it changes anything for someone about to board a plane.
Some of it does, though, and the past year contained more of it than usual. This is what actually moved, what it means if you travel, and the equally important part that most coverage skips: what has not changed at all.
Last reviewed July 2026.
⚡ The Short Summary
Three things happened that a traveller would notice:
The rest is genuinely industry news, and it is fine to ignore it.
📱 The First iPhone With No SIM Tray Anywhere
The iPhone 17 Air, announced in September 2025, is eSIM-only in every market. Apple removed the tray entirely to fit a 5.5 mm chassis, so there is no regional version with a slot.
That is a first. Until then, eSIM-only iPhones existed only in the United States: the iPhone 14 was the first eSIM-only generation there in 2022, and every US model since has followed, while the rest of the world kept a tray.
The rest of the iPhone 17 line follows the older pattern. iPhone 17, 17 Pro and 17 Pro Max are eSIM-only in the US and keep a physical tray elsewhere. All four models support two active eSIMs.
What it means for you
If you own or buy an iPhone 17 Air, a local physical SIM is no longer a fallback anywhere. That is fine as long as your destination has eSIM availability, and it is one more reason to install a travel plan before you fly rather than planning to sort it out on arrival.
For everyone else, nothing changes yet. Your tray is still there.
🇨🇳 China Opened Up
This is the biggest one for travellers, and the least covered outside the region.
For years, mainland China was the exception every compatibility guide had to write around. Phones sold there, including iPhones, shipped with two physical SIM slots and no eSIM chip, to meet local regulations. Not a software limitation, a different piece of hardware.
That changed in October 2025:
What it means for you
Two practical consequences.
If you bought a phone in mainland China, the old blanket advice no longer holds. A recent handset may well support eSIM where an older one does not. Check for an EID rather than assuming either way.
If you are travelling to China, availability is opening but it is early. Coverage of what works for visitors specifically is still thin, so verify before you rely on it rather than after you land.

🌏 eSIM-Only Spreads Past the US
Between the iPhone 17 Air globally and the US line-up, a growing share of new phones have no SIM tray at all.
This is mostly good for travellers. An eSIM-only phone forces the thing you should be doing anyway, which is arranging data before departure instead of queuing at an airport kiosk.
It removes one safety net, though, and it is worth naming: with no tray, a local physical SIM is no longer the fallback when something goes wrong. If your eSIM fails to install, or your provider has an outage, you cannot walk into a shop and buy a plastic card.
The practical answer is not complicated. Install before you fly, on home Wi-Fi, and confirm the profile appears in your settings before you leave. Our guide on when the clock actually starts covers why installing early costs you nothing.
🤖 Android Is Following, Unevenly
Android has supported eSIM since the Pixel 3 in 2018, but adoption below the flagship tier has been slow and remains patchy.
The trend through 2025 and 2026 is that eSIM is standard on flagships and increasingly common on upper mid-range models, while budget phones still frequently ship without it. That means "my phone is from 2024" is not on its own an answer. The price tier matters as much as the year.
A dial code settles it in ten seconds: *#06#, then look for an EID. Full method in is my phone eSIM compatible.
🔮 What Is Coming: iSIM
The next step after eSIM is iSIM, which integrates the SIM function directly into the phone's main processor rather than putting it on a separate embedded chip. Less board space, lower power draw, same idea from the user's point of view.
Industry bodies have published the specifications and analysts expect meaningful growth in iSIM connections, driven mostly by connected devices rather than phones.
What it means for you
Right now, nothing. iSIM behaves like eSIM from where you stand: you install a profile and it works. It is worth knowing the word exists so a marketing page cannot confuse you with it, and worth ignoring beyond that until phones ship with it in volume.
🧊 What Has Not Changed
This section matters more than the news, because most of the questions we get are about things that did not move.
Your existing phone did not gain eSIM. No announcement, update or regulation adds a chip to hardware that lacks one. If *#06# shows no EID today, it never will.
Carrier locks still exist. A subsidised phone can have a perfectly good eSIM chip and still refuse a foreign profile. This remains the most common reason a compatible phone fails.
An eSIM still uses the same towers. It is not a separate network. Coverage in a valley or on a ferry is whatever the local operator provides, exactly as with a plastic SIM.
Travel eSIMs are still data-only. You keep your own number for calls and texts on your physical SIM, or on your primary eSIM line.
Roaming charges did not go away. Nothing about eSIM adoption changes what your home operator bills for using their network abroad. That is still the comparison worth making.
❓ Frequently Asked Questions
What is the biggest recent eSIM change for travelers? Mainland China opening to eSIM on smartphones in October 2025, after years as the one major market where the hardware was absent. That reshapes advice that had been stable for years.
Is the iPhone 17 eSIM-only everywhere? Only the iPhone 17 Air, which has no SIM tray in any market. The standard 17, 17 Pro and 17 Pro Max are eSIM-only in the US and keep a tray elsewhere.
Does my Chinese phone support eSIM now?
It depends on when it was made. Models sold in mainland China before the October 2025 change shipped without an eSIM chip and cannot gain one. Recent handsets may support it. Dial *#06# and look for an EID.
Are physical SIM cards being discontinued? Not imminently, and not by regulation. Individual manufacturers are removing trays from individual models. Most phones sold worldwide today still have one.
Should I wait for iSIM before buying an eSIM? No. iSIM is a hardware implementation detail that behaves identically from the user's side. There is nothing to wait for.
Is eSIM adoption making travel data cheaper? Indirectly. More competition among providers has pushed entry prices down, and plans now start at $3.00 for 1 GB. The bigger saving is still against carrier roaming rather than against other eSIMs.
Will my old phone ever get eSIM through an update? No. It is a physical chip. Software cannot add one.
