What checks out before payment.

eSIM supported

iPhone 15 (2023) ships with eSIM hardware.

Carrier coverage

3 partner carriers in Japan · auto-handoff between them.

Speed band

180 – 320 Mbps urban · 28 ms RTT.

Install · IOS

6 steps from QR to online.

  1. 01

    Open Settings on your iPhone

    Tap the Settings app (gray gear icon) from your home screen or App Library.

  2. 02

    Go to Cellular (or Mobile Data)

    Scroll to Cellular. On some regions iOS labels this Mobile Data instead.

  3. 03

    Tap Add eSIM

    Choose Add eSIM (older iOS calls this Add Cellular Plan).

  4. 04

    Choose Use QR Code

    Tap Use QR Code, then open the eSIM email from travel.to on another device and scan the QR.

  5. 05

    Label the line travel.to

    When iOS asks for a label, pick travel.to so you can tell it apart from your home SIM.

  6. 06

    Confirm and finish

    Confirm the default line settings. Your phone will activate the eSIM on landing — you don't need to do anything else until you reach your destination.

Once installed, the eSIM is dormant until iPhone 15 reaches a partner carrier's network in Japan — typically the moment you land. No manual switch, no carrier app.

iPhone 15 in Japan

Common questions.

Yes. iPhone 15 ships with eSIM hardware, and travel.to routes it onto NTT Docomo, SoftBank, and KDDI au in Japan. The line activates the moment you land — install takes under two minutes and is fully refundable if it fails to activate.
It depends where you bought it. US-market iPhone 15 units are eSIM-only with no physical SIM tray, so the travel.to eSIM is the line you install — there is nothing to swap. International iPhone 15 units keep a physical SIM tray, so your home SIM stays in while travel.to runs on the eSIM.
On iPhone 15 open Settings → Cellular → Add eSIM, choose Use QR Code, and scan the QR from your travel.to email. That is 6 taps from QR to online. iOS labels the path "Mobile Data" in some regions.
Under two minutes. The QR arrives by email seconds after payment; 6 taps later the profile is installed on iPhone 15. It stays dormant until you reach a partner network in Japan (UTC+9 year-round) — usually the instant you land, before you have changed your clock.
In Japan we route on NTT Docomo, SoftBank, and KDDI au. iPhone 15 hands off automatically to whichever has the strongest signal where you are — you do not pick the carrier, the phone does.
180 – 320 Mbps urban · 28 ms RTT. iPhone 15 negotiates the fastest band the local network offers, so in covered areas you get the same speeds a native SIM would pull on the same carrier.
Default home-carrier roaming in Japan runs about $22 – 45 per GB. A travel.to plan for Japan sits an order of magnitude below that, and you never get a surprise bill — you pay once, up front, for the data you chose.
No need. The airport SIM kiosks in Japan keep limited hours (Narita NRT / Haneda HND · 06:30 – 22:00) and you would queue at them with the rest of your flight. Install the travel.to eSIM on iPhone 15 before you board and you walk straight past them, already online.
Three carriers per region · auto-failover below signal threshold iPhone 15 falls back automatically — you never have to switch networks by hand.
Yes. Top-ups reuse the Japan eSIM profile already on iPhone 15 — no new QR scan, no second install. Same line, fresh data, added from your Japan order page in one tap.
Full refund if the Japan eSIM fails to activate on iPhone 15. Half refund if it activates but underperforms on NTT Docomo, SoftBank, and KDDI au (and if you used under 500 MB, you get the full amount). One click from your dashboard — no email thread.
A few iPhone 15-specific notes: First iPhone generation widely available with USB-C — eSIM activation flow is unchanged. Supports up to 8 eSIM profiles stored, 2 active simultaneously. Beyond that, the travel.to install flow in Japan is the standard iOS path.
