Every iPhone from the XS (2018) onwards takes a Japan eSIM, and the install is the same five taps on all of them: Settings → Cellular → Add eSIM → Use QR Code, then leave the plan switched off until you land. The only provider choice that actually changes the iPhone experience is Airalo, whose iOS app installs the profile for you so you never open Settings at all — which is why it is our pick here even though eSIM Go is cheaper. Prices checked 20 Oct 2026.

Airalo — from $4.00
Cheapest (QR install)
eSIM Go — from $3.99
Needs manual APN
Sakura Mobile only (plus.4g)
Which iPhones Support eSIM?
The number in brackets is what matters most on an iPhone: it is how many eSIM profiles can be active at once, not how many you can store. On iPhone 13 and later you can run your home eSIM and a Japan eSIM side by side; on XS–12 the Japan eSIM has to share the phone with a physical nano-SIM instead. iPhones bought in mainland China have no eSIM support at all.
| iPhone Model | eSIM Support |
|---|---|
| iPhone XS / XR | ✓ (1 eSIM) |
| iPhone 11 series | ✓ (1 eSIM) |
| iPhone 12 series | ✓ (1 eSIM) |
| iPhone 13 series | ✓ (2 eSIMs) |
| iPhone 14 series | ✓ (2 eSIMs) |
| iPhone 15 series | ✓ (2 eSIMs) |
| iPhone 16 series | ✓ (2 eSIMs) |
To confirm eSIM support on your device: Settings → General → About → scroll to EID. If EID is present, your iPhone supports eSIM.
Best Japan eSIMs for iPhone
AiraloBest Overall for iPhone
Airalo is the smoothest eSIM experience on iPhone, because it is the only one of the four with a native iOS app that can install the profile directly — you never open Settings → Cellular at all. Plans start at $4.00 / 1 GB / 3 days.
Pros
- +Dedicated iOS app installs the profile for you — no QR scan needed
- +Top up from the app without touching iPhone Settings
- +24/7 live chat support
- +Trusted by 10M+ travellers worldwide
Cons
- −Data-only (no voice calls or SMS)
- −Requires eSIM-compatible iPhone (XS or later)
HolaflyBest Unlimited for iPhone
If you stream, use FaceTime Video heavily, or simply do not want to watch iOS's data meter, an unlimited plan removes the question. Holafly unlimited starts at $11.90 (Unlimited / 3 days) — but note the 1 GB/day hotspot cap if you plan to tether an iPad or Mac.
Pros
- +Unlimited on-device data — nothing to monitor in Settings → Cellular
- +Plain QR-code install, so it works on every eSIM iPhone back to the XS
- +Popular with US & European travellers
Cons
- −Data-only (no voice calls or SMS)
- −Hotspot capped at 1 GB/day — poor for tethering an iPad
- −Pricier than capped alternatives
Holafly is not available through our links — Airalo is our recommended alternative.
eSIM GoBest Budget for iPhone
eSIM Go has no iOS app, so you install it the manual way: Settings → Cellular → Add eSIM → Use QR Code. That is two minutes of work for the lowest price of the four, from $3.99 / 1 GB / 7 days.
Pros
- +Cheapest Japan eSIM at $3.99 / 1 GB / 7 days
- +Docomo network — excellent rural coverage
- +Instant QR code activation via iPhone Settings
- +Works in 190+ countries
Cons
- −Data-only (no voice or SMS)
- −No iOS app — install is QR-code only
- −Email-only customer support
Sakura MobileBest for Long Stay
For longer stays, Sakura Mobile is the only tourist option with real English phone support and a voice-call option. One iPhone-specific caveat: it is the only provider on this page that may need a manual APN (plus.4g) under Settings → Cellular → Cellular Data Network. Plans from $18.07 / 9 GB / 3 days.
Pros
- +Voice calls & SMS available (on their physical SIM plans)
- +English phone & email support
- +Physical SIM or eSIM available
- +Best for stays of 1 month+
Cons
- −Higher price than data-only eSIMs
- −The only provider here needing a manual APN entry on iPhone (plus.4g)
- −Not ideal for short trips
How to Install eSIM on iPhone
Under two minutes, done at home before you fly. These five steps are iPhone-specific — for Android, iPad, Galaxy Tab or Pixel Tablet, use the multi-device setup guide instead.
Check for an EID first (Settings → General → About)
Scroll to the bottom of the About screen. If an "EID" row is listed your iPhone has eSIM hardware; if it is missing, the handset cannot take a Japan eSIM at all and no amount of setup will change that.
Install over WiFi at home, not at the airport
Downloading an eSIM profile needs an internet connection, and the one place you won't have one is the arrivals hall. Do this step days before you fly.
Settings → Cellular → Add eSIM → Use QR Code
On iPhone 13 and later the "Add eSIM" row sits near the top of the Cellular screen; on XS–12 you scroll past your existing plan to find it. Airalo users can skip this entirely and install from the Airalo app instead.
Label it "Japan" when iOS asks
iOS defaults to names like "Secondary" or the carrier's own label, which gets confusing once two plans are listed. Naming it "Japan" makes the arrival-day toggle obvious.
Leave the plan toggled OFF until you land
An installed-but-off profile costs nothing and cannot be charged. Switch it on after the cabin crew clears flight mode, then set it as the data line.
Keeping Your Home Number Live Alongside It
The short version for iPhone: set your home SIM as Default Voice Line, set the Japan eSIM as Cellular Data, turn Data Roaming off on the home line, and switch off Allow Cellular Data Switching so iOS cannot quietly fall back to your home carrier when the Japan signal dips. That last toggle is the one that produces surprise roaming bills.
The full dual-SIM walkthrough — including the Android equivalents and what to do when a profile disappears after a restart — is in our step-by-step eSIM setup guide for Japan. If you are still at the stage of asking whether eSIM works in Japan at all, start there: it covers the carrier-lock check, the markets where Apple ships iPhones without eSIM, and how a Japan plan compares with roaming and pocket WiFi.
