Complete iPhone eSIM Journey – From “Does It Work?” to “I’m Connected”

Here’s the path most users follow when setting up eSIM on iPhone.

Which iPhones support eSIM? – quick answer

eSIM arrived on iPhones with the 2018 models: iPhone XR, XS, and XS Max. All later iPhones (11, 12, 13, 14, 15, 16, 17, and SE 2nd/3rd gen) also support eSIM – with one major regional exception: mainland China models (including Hong Kong in some cases) either lack eSIM or have dual physical SIM slots.

• iPhone XR, XS, XS Max (2018): ✅ First iPhones with eSIM
• iPhone 11, 11 Pro, 11 Pro Max: ✅ Full eSIM support (mainland China: dual physical SIM, no eSIM)
• iPhone SE (2nd gen 2020, 3rd gen 2022): ✅ eSIM support
• iPhone 12, 12 mini, 12 Pro, 12 Pro Max: ✅ eSIM + first 5G support
• iPhone 13, 13 mini, 13 Pro, 13 Pro Max: ✅ eSIM + improved dual‑eSIM capabilities
• iPhone 14, 14 Plus, 14 Pro, 14 Pro Max: ✅ US models are eSIM only (no physical SIM tray); other regions have physical SIM + eSIM
• iPhone 15, 15 Plus, 15 Pro, 15 Pro Max: ✅ Same as iPhone 14 – US eSIM only, global physical SIM + eSIM
• iPhone 16, 16 Plus, 16 Pro, 16 Pro Max: ✅ eSIM support continues; US remains eSIM only
• iPhone 16e: ✅ New budget model – supports eSIM (region‑dependent for physical SIM)
• iPhone 17, 17 Pro, 17 Pro Max, 17 Air: ✅ Expected full eSIM support; US models likely eSIM only

iPhone 8, 8 Plus, and iPhone X (2017) do NOT support eSIM – they use physical SIM only. If you own one, you cannot use any eSIM service.

The official Apple eSIM support page provides additional details on compatible models. The technology behind eSIM is governed by the GSMA standard SGP.22, ensuring global interoperability across devices and carriers.

Complete iPhone eSIM Compatibility Table – iPhone 8 through iPhone 17

When Did iPhones Start Using eSIM? – Historical Timeline

• 2017 and earlier (iPhone 8, X, etc.) – No eSIM. Physical SIM only.
• 2018 (iPhone XR, XS, XS Max) – First eSIM iPhones. Dual SIM: one physical nano‑SIM + one eSIM.
• 2019 (iPhone 11 series) – Same eSIM functionality as 2018 models; mainland China gets dual physical SIM instead.
• 2020 (iPhone SE 2nd gen, iPhone 12 series) – eSIM continues; iPhone 12 adds 5G on eSIM.
• 2021 (iPhone 13 series) – First support for two active eSIMs (dual eSIM) on some carriers.
• 2022 (iPhone SE 3rd gen, iPhone 14 series) – US models become eSIM only (no physical SIM tray).
• 2023 (iPhone 15 series) – US continues eSIM only; global retains physical SIM + eSIM.
• 2024 (iPhone 16 series) – Same as iPhone 15; iPhone 16e introduced as budget eSIM model.
• 2025 (iPhone 17 series) – Expected to continue the same regional split.

So the first iPhone with eSIM was the iPhone XR/XS in September 2018. That’s when iPhone started using eSIM.

How to Verify If Your iPhone Has eSIM (3 Methods)

Method 1: Dial *#06# (universal, no settings needed)

1. Open the Phone app.
2. Dial *#06# and press call.
3. Look for a 32‑digit EID (Embedded Identity Document – think of it as your phone’s eSIM serial number). If present, your iPhone has eSIM hardware.
4. If you only see IMEI numbers (IMEI1, IMEI2) and no EID, your device lacks eSIM (typical for mainland China models or iPhones older than XR).

Method 2: Check in Settings

Go to Settings > General > About. Scroll down. If you see “Available SIM” or “Digital SIM” with an EID number, eSIM is present.

Method 3: Try adding a cellular plan

Go to Settings > Cellular > Add Cellular Plan. If the option is visible and tappable, your phone supports eSIM. If grayed out or missing, no eSIM.

What to Look For – Quick Reference

Detailed Breakdown by iPhone Generation

iPhone 8, 8 Plus, iPhone X (2017)

These models predate eSIM hardware entirely. If you own an iPhone 8 or iPhone X, you cannot use eSIM – physical SIM only. The same applies to the iPhone 7 and earlier.

iPhone XR, XS, XS Max (2018)

The iPhone XR, XS, and XS Max are the first iPhones with eSIM support. All three models work with one physical SIM and one eSIM simultaneously (dual SIM dual standby). They do not support 5G.

iPhone 11, 11 Pro, 11 Pro Max (2019)

iPhone 11 series (including the Pro and Pro Max) supports eSIM globally. However, mainland China versions have dual physical SIM slots and no eSIM. If you have a global iPhone 11, you can use eSIM for 4G LTE data.

iPhone SE (2nd gen 2020, 3rd gen 2022)

Both generations of the iPhone SE support eSIM. They are excellent budget options for eSIM users, offering the same eSIM functionality as the flagship models at a lower price.

iPhone 12 series (2020)

The iPhone 12, 12 mini, 12 Pro, and 12 Pro Max all support eSIM. They were the first iPhones to offer 5G connectivity on eSIM. Dual SIM works as one physical SIM + one eSIM.

iPhone 13 series (2021)

iPhone 13 series (including mini, Pro, Pro Max) supports eSIM and introduces dual eSIM capability – you can have two active eSIMs simultaneously (no physical SIM needed). This is also the first generation where iPhone 13 dual eSIM became a standard feature.

iPhone 14 series (2022)

All iPhone 14 models support eSIM, but with a major change: US models are eSIM only – they have no physical SIM tray. Global models still offer a physical SIM slot plus eSIM. iPhone 14 eSIM only is the reality for US customers.

iPhone 15 series (2023)

iPhone 15 series follows the same regional split: US models are eSIM only; global models have physical SIM + eSIM. So iPhone 15 eSIM or physical sim depends entirely on where you buy it.

iPhone 16 series (2024)

iPhone 16 series continues the same pattern. US models are iPhone 16 eSIM only; international versions retain the physical SIM slot. iPhone 16 dual eSIM is standard across the lineup.

iPhone 16e (2025)

The iPhone 16e is Apple’s new budget model, positioned below the main iPhone 16 lineup. It supports eSIM on all models – US versions are eSIM‑only, while global versions retain a physical SIM slot alongside eSIM.

iPhone 17 series (2025)

iPhone 17 series (including 17, 17 Pro, 17 Pro Max, and 17 Air) continues the same regional split established with iPhone 14. US models are expected to be eSIM‑only; global models retain physical SIM + eSIM.

How to Activate eSIM on iPhone (Step by Step)

For complete activation details on all iPhone models, see our iPhone eSIM activation guide.

Activating a Travel eSIM (Most Common)

1. Buy a travel eSIM plan – e.g., a Roami free trial eSIM.
2. Before you travel (on Wi‑Fi), go to Settings > Cellular > Add Cellular Plan.
3. Scan the QR code or enter the activation code manually.
4. Label your plan (e.g., “Japan May”).
5. Choose your default line for voice, data, and iMessage.
6. At your destination, go to Settings > Cellular > [your eSIM plan] and turn Data Roaming ON.

iOS 18 tip: If you’re on iOS 18, the “Add Cellular Plan” interface has been redesigned with a more prominent QR scanner and a smoother activation flow. You’ll see a progress indicator during the profile download.

Activating a Carrier eSIM (e.g., Verizon, T‑Mobile, AT&T, Jio)

Your iPhone must be carrier‑unlocked to use a different carrier’s eSIM. Check Settings > General > About > Carrier Lock – it must say “No SIM restrictions.”

Activation Stuck? Quick Fixes

How Many eSIM Profiles Can an iPhone Store?

iPhones can store up to 8 eSIM profiles at a time, but the exact number depends on the iPhone model and iOS version.

How to Manage Multiple eSIM Profiles

• Delete unused profiles: Settings > Cellular > tap the plan > Remove Cellular Plan. This frees up storage for new profiles.
• Switch between stored eSIMs: Settings > Cellular > tap the desired plan > Turn On This Line.
• Rename profiles: Settings > Cellular > tap the plan > Cellular Plan Label – choose a custom name (e.g., “Japan Trip”).

Using Physical SIM and eSIM Together (Dual SIM)

All iPhones from XR through 13 (global) and global 14–17 support one physical SIM + one eSIM active at the same time. US eSIM‑only models (14–17) use dual eSIM instead.

How to Set Up Dual SIM

1. Insert your physical SIM (or have your first eSIM active).
2. Add a second eSIM via Settings > Cellular > Add Cellular Plan.
3. In Settings > Cellular, assign:
   • Default Voice Line – which line makes calls
   • Default Data Line – which line uses mobile internet
   • Cellular Data Switching – allow automatic switching if the primary data line loses signal (use with caution abroad to avoid roaming charges)

Dual SIM Configuration – Recommended Settings for Travel

Example: Traveling from US to Japan

• Keep your US physical SIM (or home eSIM) for calls/SMS.
• Buy a Japan travel eSIM for data.
• Set Japan eSIM as Default Data Line and turn on Data Roaming for that line.

eSIM vs Physical SIM – Which Is Better on iPhone?

Verdict: eSIM is more convenient and secure for travel and daily use. Physical SIM is only better if you frequently swap between incompatible devices or need a backup when traveling to regions with limited eSIM support (like China).

Regional Differences: China, Hong Kong, US, and Global – iPhone eSIM Variants

• Mainland China models (model number ends with CH/A): No eSIM – dual physical SIM instead.
• Hong Kong & Macau models: Typically physical SIM + eSIM (same as global).
• US models (iPhone 14–17): eSIM only – no physical SIM tray.
• Global models (Europe, Asia non‑China, etc.): Physical SIM + eSIM.

If you travel frequently, a global version (physical + eSIM) offers more flexibility than a US eSIM‑only model.

Special Cases: eSIM‑Only iPhones (US Models 14–17)

What “eSIM Only” Means

• No physical SIM slot.
• You must activate at least one eSIM to use cellular.
• Dual SIM works via two eSIMs (dual eSIM).

First‑Time Setup for eSIM‑Only iPhone

• Transfer eSIM from old iPhone during setup.
• Or activate via carrier app.
• Or skip and add later via Settings > Cellular > Add Cellular Plan.

Traveling with an eSIM‑Only iPhone

• Install travel eSIM before departure (on Wi‑Fi).
• At destination, set travel eSIM as Default Data Line and turn on Data Roaming.
• Keep home eSIM active for calls (but beware roaming charges if you answer).

What If Your eSIM‑Only iPhone Breaks Abroad?

You cannot insert a physical SIM as a backup. Your options:

• Buy a new eSIM from a local carrier that supports online purchase.
• Use Wi‑Fi only.
• Keep a backup eSIM QR code in your email.
• Carry a secondary device (old phone) with a physical SIM slot as backup.

How to Transfer eSIM from Old iPhone to New iPhone

Method 1: Quick Transfer (iOS 16+)

1. During new iPhone setup, choose “Transfer eSIM from nearby iPhone”.
2. Keep both phones close, connected to Wi‑Fi, and signed into the same Apple ID.
3. Follow the on‑screen prompts – the eSIM transfers automatically.

Method 2: Carrier App Transfer

1. On the new iPhone, download your carrier’s app.
2. Log in and look for “Activate eSIM” or “Transfer eSIM”.
3. Follow the carrier‑specific flow.

Method 3: Delete and Re‑install (Last Resort)

1. On the old phone: Settings > Cellular > tap the eSIM > Remove Cellular Plan.
2. On the new phone: Settings > Cellular > Add Cellular Plan > scan the original QR code (or use carrier app).
3. ⚠️ Warning: Travel eSIMs usually cannot be re‑installed – contact your provider first.

Method 4: Physical SIM Conversion (If You Have a Physical SIM)

1. On the new phone: Settings > Cellular > Add Cellular Plan > “Convert from physical SIM”.
2. Follow the prompts – this converts your physical SIM to an eSIM on the new device.
3. The physical SIM becomes inactive after conversion.

💡 Pro Tip: Always keep your original eSIM QR code or activation email in a safe place (cloud storage, password manager). If anything goes wrong during transfer, you’ll have a backup.

Buying a Used iPhone for eSIM Travel

What to Avoid

• Mainland China models (CH/A) – no eSIM.
• iPhone 8, X – no eSIM at all.
• Carrier‑locked iPhones – risky for travel eSIM.
• US eSIM‑only models as a backup phone (no physical SIM slot).

In‑Person Verification Checklist (Before Buying)

What Happens to eSIM When You Sell or Reset Your iPhone?

Before Selling Your iPhone – Secure Erasure Steps

What Happens If You Don’t Remove eSIM Before Reset?

• The eSIM profile becomes orphaned – it’s still tied to your carrier but inactive on the device.
• The next owner won’t be able to use it (it’s still tied to your account).
• You may still be billed for the plan if it’s active.

Can You Reactivate an eSIM After Factory Reset?

• Travel eSIMs: Usually not – they’re one‑time install. Contact your provider for a new QR code.
• Carrier eSIMs (Verizon, T‑Mobile, etc.): Yes – use the carrier app to re‑download the profile.
• If you kept the original QR code: You may be able to re‑scan it (if not expired).

⚠️ Warning: Always remove eSIM profiles before erasing your iPhone. Orphaned eSIMs can cause activation issues for the next owner and billing issues for you.

What is the first iPhone with eSIM? The iPhone XR, XS, and XS Max (released September 2018) are the first iPhones to support eSIM. If you have an iPhone 8 or iPhone X, you cannot use eSIM.

How do I transfer my eSIM from an old iPhone to a new one? During setup of your new iPhone, look for the option “Transfer eSIM from nearby iPhone”. Keep both phones close. If that doesn’t work, delete the eSIM from the old device (after confirming it’s backed up) and re‑install using the original QR code or carrier app. See the detailed transfer section above.

Why does my iPhone say “Cellular Plan Cannot Be Added”? You may have too many stored eSIM profiles (iPhones can store around 8). Go to Settings > Cellular, delete any unused plans, restart your phone, and try again. Also ensure the QR code hasn’t expired.

What does “eSIM only” mean on US iPhones? It means the iPhone has no physical SIM tray – you must use one or more eSIMs for cellular service. Dual SIM works via two eSIMs (dual eSIM).

How many eSIM profiles can I store on my iPhone? iPhone can store up to 8 eSIM profiles, but only one or two can be active at once (depending on the model). See the storage limit table above.

What happens to my eSIM if I reset my iPhone? If you erase all content and settings without removing eSIM first, the profile becomes orphaned. Always remove eSIM profiles before resetting (Settings > Cellular > Remove Cellular Plan).

Can I convert my physical SIM to eSIM on iPhone? Yes – on iPhone 13 and newer, go to Settings > Cellular > Add Cellular Plan > “Convert from physical SIM”. This transfers your physical SIM to an eSIM on the same device. The physical SIM becomes inactive after conversion.

What’s the cheapest iPhone with eSIM? The iPhone XR (used) is the cheapest eSIM‑capable iPhone at around $100–150. The iPhone SE (3rd gen) is the cheapest new eSIM iPhone.

How do I check if my iPhone is carrier‑locked? Settings > General > About > Carrier Lock. If it says “No SIM restrictions”, your iPhone is unlocked and can use any eSIM. If it says “SIM locked”, contact your carrier for an unlock.

What’s the difference between iPhone 13 dual eSIM and iPhone 12 dual SIM? iPhone 12 supports one physical SIM + one eSIM. iPhone 13 supports two active eSIMs (no physical SIM needed) OR one physical SIM + one eSIM. This makes iPhone 13 the first model with true dual eSIM capability.

Can I use an eSIM on iPhone 17 if I bought it in the US? Yes – but US iPhone 17 models are eSIM‑only (no physical SIM slot). You’ll need to use eSIM for all cellular service.

How do I fix eSIM not showing up in Settings after an iOS update? This is a known iOS bug. Go to Settings > General > About – if your EID number appears but the eSIM doesn’t show in Cellular, restart your iPhone. If that doesn’t work, go to Settings > Cellular > Add eSIM – sometimes the phone detects the existing profile and re-adds it automatically.
