What Is an eSIM on iPhone?
An eSIM, short for “embedded SIM,” is a digital SIM card built right into your iPhone. Instead of swapping tiny plastic cards, you activate your cellular plan directly in Settings. This means your phone connects to the network just like it would with a physical SIM, but without the hassle of a card. SIM cards have shrunk over the years—from credit-card size to nano chips—but the eSIM takes it a step further by eliminating the physical card entirely.
What makes eSIM technology particularly impressive is its ability to transform your iPhone into a dual-SIM device without requiring additional physical slots. This lets you keep your primary number from home while adding a local plan when traveling, for example, during a weekend trip to Japan. Newer iPhone models even allow two active eSIMs simultaneously. Changing carriers? No need to wait for a SIM card shipment or visit a store—you can handle everything comfortably from your couch.

Complete List of iPhones with eSIM Support
Apple might not always be first to new tech, but when it commits, it goes all in. Since 2018, eSIM has evolved from a niche feature to the standard way iPhones connect to cellular networks. Some recent iPhones even skip the physical SIM tray altogether.
Here’s a handy rundown of every eSIM-compatible iPhone, starting with the latest models:
Latest iPhone Models (iPhone 17 Series, iPhone Air, and iPhone 16 Series)
These are Apple's newest phones, and they fully embrace eSIM technology. Some have ditched the SIM tray entirely, while others support two active eSIMs simultaneously. Plus, the iPhone 17 Pro even comes in a bold neon orange!
-
iPhone 17, 17 Pro, 17 Pro Max: All support two active eSIMs. In the US, these models come without a physical SIM tray, freeing up internal space for a bigger battery—a win for outdoor adventurers.
-
iPhone Air: Apple's thinnest iPhone yet and their first globally eSIM-only model. No physical SIM tray anywhere in the world. It even supports eSIM in China, which is a first.
-
iPhone 16, 16 Plus, 16 Pro, 16 Pro Max: These support dual eSIMs with no SIM tray in the US. Other regions still get a nano-SIM slot alongside eSIM support.
-
iPhone 16e: A compact and more budget-friendly option that offers full eSIM support and features a SIM-free design in selected markets.
-
Great for travelers wanting connectivity without the Pro price tag.
The iPhone 17 series isn’t the first to eliminate the SIM tray in the US, but it’s the first to use the freed-up space for a meaningful upgrade: a larger battery. This shows how eSIM is no longer just a convenience—it’s shaping iPhone hardware itself.
iPhone 15 Series (2023)
The iPhone 15 lineup continued Apple’s move toward eSIM-only devices in the US, ditching the physical SIM tray entirely. International versions still come with a nano-SIM slot but also support two active eSIMs simultaneously. By this generation, eSIM became the default for cellular connectivity.
iPhone 14 Series (2022)
The iPhone 14 series marked a big change: US models shipped without a physical SIM tray, making them the first eSIM-only iPhones sold there. All models support dual eSIM functionality. Outside the US, Apple still offered a physical SIM slot alongside eSIM.
iPhone 13 Series (2021)
The iPhone 13 lineup was a major step forward, allowing two active eSIMs at once, turning the phone into a true dual-line device for work and travel. They still support one physical nano-SIM, so you can mix and match eSIM and physical SIM as you like.
iPhone 12 Series (2020)
The iPhone 12 series offers dual SIM capability with one physical nano-SIM and one eSIM. Although only one eSIM can be active at a time alongside the physical SIM, multiple eSIM profiles can be stored and switched between as needed.
iPhone 11 Series (2019)
The iPhone 11 series supports dual SIM with one physical nano-SIM and one eSIM. However, two active eSIMs are not supported. Some models sold in mainland China and Hong Kong/Macao use two physical SIM cards instead of supporting eSIM functionality.
iPhone XR, XS, and XS Max (2018)
These were the first iPhones with eSIM support, allowing one physical nano-SIM and one eSIM simultaneously. Mainland China models typically have dual physical SIMs and no eSIM.
iPhone SE Models
Apple’s compact iPhone also supports eSIM:
-
iPhone SE (3rd generation, 2022): Supports one physical nano-SIM and two active eSIMs simultaneously for true dual-line flexibility.
-
iPhone SE (2nd generation, 2020): Supports one physical nano-SIM and one eSIM, with multiple eSIM profiles storable.
If you want a small iPhone with modern connectivity, the SE 3 is a great choice.
iPhones That Do NOT Support eSIM
eSIM support started with the iPhone XR and XS in 2018. Older models don’t have eSIM and rely solely on physical SIM cards:
-
iPhone X and earlier models such as iPhone 8, 7, 6s, 6, and the first-generation iPhone SE.
If you use one of these, your setup isn’t broken—you still get reliable service with physical nano-SIMs. But if you want dual lines or easier travel data, consider upgrading to an eSIM-compatible iPhone.
Regional Differences in eSIM Support
Apple sells region-specific iPhone variants, and eSIM support varies:
-
Mainland China: Most iPhones sold here have dual physical nano-SIM slots and no eSIM. The exception is the iPhone Air, which supports eSIM even in China.
-
Hong Kong and Macao: Most models have dual physical SIMs, but some support eSIM, including iPhone Air, iPhone 13 mini, iPhone 12 mini, iPhone SE (2020), and iPhone XS.
If you want full eSIM support, choose a global model or the iPhone Air.
How Many eSIMs Can an iPhone Store?
For a broader look at compatible phones, tablets, and wearables, see our eSIM supported devices compatibility guide.
Think of eSIM profiles like phone numbers saved on your device. Most iPhones can store eight or more profiles. You can switch between them anytime in Settings.
-
On iPhone 13 and newer, you can have two active eSIMs running simultaneously.
-
On earlier models like the XR, XS, 11, 12, and the iPhone SE (2nd generation), you can use one active eSIM alongside a physical nano-SIM.
eSIM vs. Physical SIM: Which Is Better for iPhone?
eSIM removes the need for plastic SIM cards, making mobile plans easier to manage digitally. Apple started adopting eSIM with the iPhone XS and has since moved toward eSIM-only devices in the US.
Benefits of eSIM include:
-
Quick plan activation without visiting stores.
-
Dual SIM functionality with two active lines.
-
Easy switching between carriers and plans.
Physical SIMs still have advantages, especially for older phones or regions where eSIM isn’t widely supported. They’re easy to swap between devices instantly.
For most users, eSIM wins on convenience and flexibility, especially with newer iPhones supporting two active eSIMs.
