• iPhone 13 and later can run two eSIMs active at the same time (dual eSIM).
• iPhone 14 and later US models have no physical SIM tray; Europe and most other regions kept the nano-SIM tray through the iPhone 17 series.
• iPhone Air (2025) is eSIM-only worldwide - Apple’s first global eSIM-only iPhone.
• iPhone 18 Pro and 18 Pro Max (2026) are eSIM-only in 12 markets (US, Canada, Mexico, Japan, Guam, US Virgin Islands and 6 Gulf states) and keep a nano-SIM tray elsewhere.
• iPhone Duo (2026), Apple’s first foldable, has no SIM tray in any country.
• Mainland China: only iPhone 17e, iPhone Air and iPhone Duo support eSIM; other China models are dual nano-SIM without eSIM.

📱 eSIM-Only iPhone Models by Region

• eSIM-only everywhere: iPhone Air, iPhone Duo.
• eSIM-only in 12 markets, nano-SIM + eSIM elsewhere: iPhone 14 / 15 / 16 / 17 / 18 series sold in the US, Canada, Mexico, Japan, Guam, US Virgin Islands, Saudi Arabia, UAE, Qatar, Kuwait, Bahrain and Oman.
• A phone sold eSIM-only stays eSIM-only wherever you take it - there is no tray to fall back on.

📱 Install a Travel eSIM on iPhone: 5 Steps

• Buy your travel eSIM and open the delivery email on your iPhone (on Wi-Fi).
• Open Settings > Cellular > Add eSIM (or Set Up Cellular in newer iOS).
• Choose Use QR Code and scan the code from the email, or tap the activation link.
• Label the plan (for example “Japan trip”) and set Default Line calls/texts to your home number.
• On arrival: turn the eSIM line on, enable Data Roaming for it, and set it as your Mobile Data line. Your home SIM keeps calls and SMS.

📱 Travel Dual eSIM Setup: Home Number + Travel Data

Keep your physical SIM or home eSIM active for calls, bank codes and WhatsApp verification, and let the travel eSIM carry the data. In Settings > Cellular, set Mobile Data to the travel eSIM and leave calls on your home line. Turn off Data Roaming on the home line so it cannot pick up roaming charges; data roaming stays ON for the travel eSIM - that is what lets it connect abroad, at no extra cost.

💡 Quick Tips

• Install the eSIM on Wi-Fi at home before you fly - airport Wi-Fi is unreliable and some installs need a stable connection.
• Never delete a working eSIM profile to “clean up” before a trip; a deleted carrier profile often requires the carrier to reissue it.
• iPhone can store eight or more eSIM profiles - keep your home line and several travel plans installed at once.

⚡ Pro Tips

• Turn on Data Roaming for the travel eSIM only. It will not cost extra - your plan is prepaid - but without it the line cannot connect to foreign networks.
• If the eSIM shows No Service after landing, toggle Airplane Mode, then check Settings > Cellular > [your eSIM] > Data Roaming.

📋 Summary

Every iPhone from the XS (2018) onward supports eSIM, and from the iPhone 13 on you can run two lines at once. Install a travel eSIM at home on Wi-Fi, keep your home number for calls and codes, and switch data to the travel eSIM when you land - no physical SIM needed on any current iPhone.
