iPhone eSIM compatibility: full model list

Here is a complete compatibility table for every eSIM-capable iPhone model, from the first eSIM iPhone to the current iPhone 16 lineup:

In short: if you have any iPhone released in 2018 or later, your device is eSIM compatible. For iPhone-specific activation instructions, also check out our eSIM installation guide for iPhone.

eSIM-only iPhones: what it means for travelers

Starting with the iPhone 14 in the US (and continuing with US iPhone 15 and 16 models), Apple completely removed the physical SIM card tray. These are "eSIM-only" devices. Here's what that means in practice for travelers:

What changes on an eSIM-only iPhone

• No nano-SIM slot on the device. You can't insert a local SIM card you buy at your destination.
• All carrier connectivity must be handled through digitally downloaded eSIM profiles.
• You can store up to 8 eSIM profiles and switch between them from Settings.
• Two eSIMs can be active at the same time (Dual eSIM), replacing what used to be Dual SIM (nano + eSIM).

Impact for international travelers

For travelers who used to buy cheap local SIM cards at destination airports, eSIM-only iPhones completely change the process. Now you must:

1. Buy a travel eSIM before you leave and install it ahead of time (the recommended method).
2. Buy an eSIM from a local carrier digitally after arriving (possible in most developed countries, but requires internet access to download it).
3. Use roaming through your regular carrier's eSIM (expensive in most cases).

Option 1 (buying a travel eSIM before you leave from a provider like PuraSIM) is clearly the best. It costs less than airport kiosk options, avoids the problem of needing data to download your eSIM, and means you'll be connected as soon as your plane lands.

How to Add an eSIM on iPhone: Step by Step

Adding an eSIM to your iPhone takes less than three minutes if you follow these steps:

1. Open Settings on your iPhone.
2. Tap Mobile Service (the exact name varies by iOS version and region; look for the option that mentions your carrier or SIM).
3. Tap Add eSIM or Add Mobile Plan. On eSIM-only iPhones, this may appear as Add Data Plan.
4. Choose Use QR Code to scan your provider's QR code. Alternatively, select Enter Details Manually if your provider gives you an activation code instead of a QR code.
5. Point your iPhone camera at the QR code in your confirmation email. Keep the code centered in the viewfinder until it scans automatically.
6. Tap Continue on the confirmation screen. Your iPhone will show the plan name and the amount of data included.
7. Wait for the profile to download (10-60 seconds with Wi-Fi).
8. Tap Done. Your new eSIM will appear in the list of mobile plans.
9. Set the new eSIM as your Default Line for mobile data if you'll use it for travel.
10. If your provider requires it, turn on Data Roaming for the new eSIM line.

That's it. Your iPhone is now set up with the travel eSIM and ready to connect when you arrive at your destination.

How to Manage Multiple eSIMs on iPhone

One of the most powerful features of eSIM on iPhone is the ability to store up to 8 profiles at the same time and switch between them without reinstalling. Here's how to manage multiple eSIMs effectively:

Name Your eSIM Plans

When you add each eSIM, the iPhone asks you to assign a label. Use descriptive names like "Home - AT&T", "PuraSIM Europe", "Japan Trip 2026". Clear labels make switching between plans obvious and error-free, especially when you're managing both your home SIM and several travel eSIMs.

Set Default Lines

In Settings > Mobile Service (or Cellular), you can independently define:

• Default Line: which plan handles outgoing calls by default
• Mobile Data: which plan provides mobile data (set this to your travel eSIM when you're abroad)
• iMessage and FaceTime: which number is used for Apple's messaging services

Switch Between Active Plans

To change which eSIM is active for data: Settings > Mobile Service > Mobile Data > select the desired plan. The change applies immediately. You can toggle between your home plan and your travel eSIM in seconds, which is handy when you return to your home country.

Remove Stored eSIMs

If you want to remove a used travel eSIM: Settings > Mobile Service > tap the plan > Delete Mobile Plan. Note that deletion is permanent; you'll need a new QR code to reinstall the same plan if it was a single-use profile.

Using Dual SIM on iPhone for Travel

Dual SIM is the feature that makes eSIM truly useful for international travelers: it lets you have two active lines at the same time on a single iPhone:

Physical SIM + eSIM (iPhone XS through the international series 13)

You keep the nano-SIM from your regular carrier in the physical tray and add a travel eSIM. Both are active at the same time. Your home number receives calls and text messages as usual; your travel eSIM handles mobile data at local rates. This is the ideal setup for anyone who needs to be reachable on their home number.

Dual eSIM (iPhone 14+ US models and some international models)

On eSIM-only iPhones, two eSIM profiles can be active simultaneously. Your home carrier's eSIM handles calls, text messages, and data in your home country; your travel eSIM handles data at your destination. The functionality is identical to physical SIM + eSIM, just without the physical card.

Practical Dual SIM Setup

• Set your travel eSIM as the default Mobile Data option to use local data rates
• Keep your home SIM/eSIM as the Default Line for calls, so your home number receives incoming calls
• Turn on Allow Mobile Data Switching if you want your iPhone to use your home plan as a backup when the travel eSIM has no signal

Common eSIM Issues on iPhone and How to Fix Them

eSIM activation on iPhone is reliable in the vast majority of cases, but here are the most frequent issues and how to solve them:

Invalid QR Code

Symptom: The iPhone shows "Invalid QR Code" or fails to scan it.
Solution: Make sure the screen brightness is high and the QR code is fully visible. Try printing the QR code or opening it on another device and scanning it from that screen. If the code still fails, contact your eSIM provider; the code may have expired or already been used.

Activation Error / "Could Not Activate Cellular Plan"

Symptom: The QR code scans but activation fails with an error message.
Solution: Check that your Wi-Fi connection is stable. Restart your iPhone and try again. Some providers require a short wait after purchase before the QR code becomes valid. If the problem persists after 15 minutes, contact your provider's support.

SIM Not Recognized / No Service

Symptom: The eSIM installs correctly but shows "No Service" in the destination country.
Solution: Check that Data Roaming is turned on for the eSIM in Settings > Cellular > your eSIM plan > turn on Data Roaming. Some plans require roaming to be enabled even though the eSIM is technically a local plan. Also verify that the plan has been activated (some activate on a scheduled date, not immediately).

eSIM Disappears After an iOS Update

Symptom: An installed eSIM profile disappears after an iOS update or iPhone restart.
Solution: eSIM profiles can be lost during a full device restore. Always save your QR codes permanently (screenshot or print them). Contact your eSIM provider with your order details to request a new QR code for reinstallation.

Incorrect APN Settings

Symptom: The eSIM shows signal but data doesn't work.
Solution: Some eSIM providers require manual APN (Access Point Name) configuration. Check your provider's setup guide for the APN details, then enter them in Settings > Cellular > your eSIM > Cellular Data Network.

Best travel eSIM plans for iPhone users

With your iPhone's eSIM capabilities confirmed, here's what to look for in a travel eSIM plan optimized for iPhone users:

For traveling to Europe

Explore PuraSIM eSIM plans for Europe with coverage in over 30 countries. 10-20 GB plans are suitable for most two-week trips across Europe. All plans install via standard QR code scanning on the iPhone, no app required.

For international travel

For trips to multiple destinations or less common countries, check out PuraSIM international eSIM plans. These cover several regions with a single plan, ideal for complex itineraries.

Key features to prioritize for iPhone

• QR code activation: Avoid providers that require their own app; native activation from iPhone Settings is simpler and more reliable.
• Clear network information: Know which carrier network your plan uses in each country.
• No speed throttling below 4G: Many cheap unlimited plans drop to 3G speeds after a daily limit; check the plan specs.
• Responsive support: Especially for eSIM-only iPhones, reliable support is critical since there's no physical SIM backup.
