The short answer: most iPhones released from 2018 onward — starting with the iPhone XS, XS Max, and XR — support eSIM. That includes the iPhone 11, 12, 13, 14, 15, and 16 series, as well as the iPhone SE (2nd and 3rd generation). Older models such as the iPhone X and earlier, along with the iPhone SE (1st generation), do not support eSIM. The first step is simply to identify your model. In this guide, we'll walk through the compatibility list, how to check in your settings, and a few easy-to-miss details. If eSIM is new to you, you may also want to read our What Is an eSIM? A Beginner's Guide.
iPhone eSIM Compatibility List
The table below is a general guide to eSIM support across the main iPhone models. Some devices — particularly those purchased in certain regions — can be exceptions, so the safest way to confirm is to check your own phone. We'll show you how in the next section.
| Series | eSIM Support | Notes |
|---|---|---|
| iPhone 16 series | Supported | Dual eSIM + physical SIM on many regional versions |
| iPhone 15 series | Supported | Same as above |
| iPhone 14 series | Supported | Same as above (U.S. versions are eSIM-only) |
| iPhone 13 series / SE (3rd gen) | Supported | — |
| iPhone 12 series | Supported | — |
| iPhone 11 series / SE (2nd gen) | Supported | — |
| iPhone XS / XS Max / XR | Supported | The first eSIM-capable generation |
| iPhone X / 8 / 7 and earlier | Not supported | Physical SIM only |
| iPhone SE (1st gen) | Not supported | Physical SIM only |
A simple rule of thumb: if your iPhone was released in 2018 or later, there's a good chance it supports eSIM. For a broader list that includes non-iPhone devices that work with Bloomy, see our eSIM-compatible devices page.
How to Check Whether Your iPhone Supports eSIM
Even if you're not sure of your exact model, you can confirm in under a minute right from your settings. Any of the methods below works.
Method 1: Look for the "Add eSIM" option in Settings
Open Settings → Cellular (or Mobile Data). If you see an option like "Add eSIM" or "Add Cellular Plan," your device supports eSIM. If that option isn't there, the device may not support eSIM, or your iOS version may be out of date.
Method 2: Check whether an EID is shown
Open Settings → General → About and scroll down. If you see an "EID" — a number around 15 digits long — your device supports eSIM. If there's no EID, the device most likely doesn't support it.
Method 3: Confirm your model name and number
Check the "Model Name" and "Model Number" under Settings → General → About, then match them against the table above. The model number is especially helpful if you're unsure where your device was originally purchased.
Before you begin, it's a good idea to update to the latest iOS via Settings → General → Software Update, which helps everything go smoothly.
Things to Watch For — Even on Supported Models
Even if your model is on the supported list, there are a few details that are easy to overlook. A quick check before you travel can save you some stress once you arrive.
SIM lock status
An iPhone bought from a carrier may be SIM-locked, which can prevent other carriers' or travel eSIMs from working. Many recently purchased devices are unlocked, but if you're unsure, ask the carrier you bought it from to confirm the lock status.
Models purchased in certain regions (e.g., mainland China)
Some iPhones sold in mainland China are designed to use two physical SIMs rather than an eSIM. Models from a few other regions, such as Hong Kong and Macau versions, can also differ. If you're using an iPhone bought abroad, we especially recommend checking your settings using the methods above.
eSIM-only models (U.S. versions)
Some iPhone 14 and later models sold in the U.S. are eSIM-only and have no physical SIM slot. eSIM works without issue on these — just keep in mind that you won't be able to insert a physical SIM.
Data-only service (an honest note)
Bloomy eSIMs are generally data-only. You can use the internet, maps, and app-based calls (such as WhatsApp) where a data connection is available, but they do not include a phone number, SMS text messaging, or traditional voice calls. If you need SMS verification codes (for example, from a banking app) or voice calling, it's worth also looking into options like a local SIM or a plan that includes a number.
Setting Up Your eSIM and Using It Abroad
Once you've confirmed compatibility, it helps to picture the setup flow. It comes down to three main steps.
- Before you leave: buy your eSIM and install it on your iPhone, for example by scanning a QR code.
- After you arrive: turn on the relevant eSIM line and enable "Data Roaming" if needed.
- Start using it: check the signal indicator and connect to the internet.
When activation happens can vary by plan, so check the instructions provided at purchase. For a step-by-step walkthrough with images, see How to set up your eSIM. Installing before departure while you're on Wi-Fi tends to be the smoothest approach.
What to Check If You Can't Connect
If you've set everything up but still can't get online, working through the points below usually helps.
- Is the eSIM line turned on? (Settings → Cellular)
- Is "Data Roaming" turned on?
- Is the line used for cellular data set to your new eSIM?
- Try toggling Airplane Mode on and off, or restart the device.
- Are you within the activation date and the valid usage period?
If the problem persists, see our detailed guide in What to do when you can't connect. You can also reach our support team anytime through the Contact page.
What You Can Do with a Bloomy eSIM
Once compatibility is confirmed, all that's left is choosing a plan for your destination. With Bloomy, you can search by country, data allowance, and number of days. A smaller allowance works well for short trips, while longer stays or heavy video streaming may call for a larger allowance or an unlimited-style plan — the lineup is designed so you can pick what fits your needs.
Not sure how much data you need? Start with Compare eSIM plans and narrow it down by destination and trip length. If you'd like plenty of data, Bloomy Unlimited Max is another option. Unlimited-style plans suit longer sessions of use, but they may include a fair-use policy, reduced speeds after a certain amount of usage, and conditions on tethering, so it's a good idea to check the latest terms before you buy. After purchase, you can view your remaining data and QR code in My Account.
You can find the full list of compatible devices (including non-iPhone models) and our other eSIM guides via the eSIM Guides index.
Summary: Start by Checking for an EID in Settings
Most iPhones from the 2018 XS/XR generation onward support eSIM. When in doubt, go to Settings → General → About and look for an EID, or check whether "Add eSIM" appears under Cellular — either takes only a few seconds. As long as you watch out for SIM lock status and region-specific models, getting ready is easy. Once you've confirmed compatibility, choose a plan that matches your destination and trip length, and install it before you leave. Plan details can change, so please check the latest information before purchasing.
