Frequently Asked Questions

What is an eSIM?

An eSIM, or embedded Subscriber Identity Module, is a virtual SIM card integrated into devices like smartphones and smartwatches. Unlike physical SIM cards, eSIMs are programmed remotely, enabling easy network switching and activation without needing physical swaps. They offer flexibility for changing carriers and plans, convenient international travel connectivity, and the management of multiple numbers on one device. While not universally supported, eSIM technology reduces the reliance on physical cards and simplifies the user experience by allowing remote provisioning of cellular services.

Does the ETravelSim Japan eSIM work on iPhone?

Yes, the ETravelSim Japan eSIM works on every iPhone from iPhone XR onwards — including XS, 11, 12, 13, 14, 15, 16, 17, Air, and SE 2020+. Your iPhone must be carrier-unlocked. Check Settings → General → About → "Carrier Lock" should read "No SIM restrictions" before buying.

Will it work at Narita / Haneda / Kansai airport?

Yes. KDDI has full 5G coverage at Narita (NRT), Haneda (HND), Kansai (KIX), and New Chitose (CTS). Your ETravelSim Japan eSIM connects automatically within 2–5 minutes of switching on cellular data after landing. Google Maps will be live as you walk to the train.

Does it cover Shinkansen tunnels?

Yes. KDDI has installed signal repeaters along all major Shinkansen routes — Tokaido, Tohoku, Hokuriku, and Sanyo lines. You'll get stable 4G LTE across most of the journey, with brief signal drops only in some of the longest mountain tunnels. Speeds resume immediately once you exit.

Does it work in rural Japan / Hokkaido / Okinawa?

Yes. KDDI covers all 47 prefectures of Japan including Hokkaido, Okinawa, Tohoku, and Kyushu. 5G is concentrated in cities and major towns. Rural areas, deep mountain regions, and smaller Okinawan islands fall back to 4G LTE, which stays fast enough for maps and messaging.

Can I make calls or get a Japanese phone number?

No. The ETravelSim Japan eSIM is data-only — there is no Japanese mobile number and no incoming or outgoing voice calls or SMS. Use WhatsApp, FaceTime, Skype, Zoom, or Google Voice over data. Your home phone number stays active on your primary SIM throughout.

Will WhatsApp work?

Yes. WhatsApp uses internet data rather than the mobile number itself, so it works perfectly on the ETravelSim Japan eSIM. You keep your existing WhatsApp account tied to your home number, and the Japan eSIM simply provides the data connection for messages, calls, and media.

How do I get the QR code after buying?

Your eSIM QR code is emailed to you within 15 minutes of payment, along with the SMDP+ address, activation code, and a step-by-step install guide. If the email doesn't arrive, check your spam folder. If it's still missing, contact ETravelSim support — average chat reply is under one hour.

What if my eSIM doesn't work in Japan?

Toggle Airplane Mode off and on, verify the ETravelSim line is set as cellular data, and enable Data Roaming for the eSIM line (the correct iOS setting for a non-primary network). If it still won't connect, message ETravelSim support — most issues resolve in under 10 minutes.

Can I install the eSIM on more than one phone?

No. The Japan eSIM QR code is single-use. Once it's scanned and installed on a phone, it cannot be transferred to a different device, and it cannot be reinstalled if you delete it. Take a screenshot of the QR before scanning so you have an emergency backup.

Is it 5G or 4G?

Both. The ETravelSim Japan eSIM delivers 5G on KDDI's network across Tokyo, Osaka, Kyoto, Nagoya, Fukuoka, Sapporo, and most major Japanese cities. Outside 5G zones, it falls back to 4G LTE automatically. Your phone must be 5G-capable hardware to actually use the 5G layer.

What happens if I use all my data before my trip ends?

On fixed-data plans (1GB to 50GB) your connection stops once the allowance is used up. You can buy a top-up plan from ETravelSim and install it as a second eSIM on the same phone — most modern iPhones and Android phones hold multiple eSIM profiles simultaneously.

Can I cancel and get a refund?

Yes — you can cancel for a full refund any time before the QR code is installed and activated on your device. Once the eSIM is scanned and connects to KDDI, the plan counts as used and is non-refundable. Contact ETravelSim support to initiate the refund.

Is my phone unlocked? How do I check?

On iPhone: Settings → General → About → "Carrier Lock" should read "No SIM restrictions". On Android, settings vary by manufacturer. Phones bought outright or fully out of contract are usually unlocked. Carrier-locked phones cannot use any travel eSIM, including ETravelSim Japan.

Is it better than buying a SIM at the airport?

For most travelers, yes. Airport SIM kiosks in Japan charge ¥3,000–¥5,000 ($20–$33) for a 7-day plan, require photo ID, and waste 30–60 minutes after a long flight. The ETravelSim Japan eSIM costs less, takes 2 minutes to activate, and works the moment you land.

What about pocket Wi-Fi rental?

Pocket Wi-Fi rental in Japan costs $5–$10 per day, requires airport pickup and drop-off, and is an extra device to charge and carry. An eSIM stays in your phone, has no pickup hassle, and works out cheaper per day on any trip longer than three days.

Will my home plan still work for calls / SMS?

Yes. Your home SIM stays active for calls and SMS on your normal home number while the ETravelSim Japan eSIM handles data. This dual-SIM setup is the main reason most international travelers choose an eSIM over a physical SIM — you don't lose your usual number.

Does it support eSIM transfer / QR re-scan?

No. Once the QR code has been scanned, it is burned and cannot be re-scanned, transferred to another phone, or reinstalled if deleted. Before scanning, take a screenshot of the QR so you have a manual backup of the SMDP+ activation code if something goes wrong.

Does it work on the Apple Watch?

No. The ETravelSim Japan eSIM is designed for smartphones and tablets only. Apple Watch cellular requires a carrier-paired plan from your home network provider — travel eSIMs cannot be installed on the Apple Watch directly. Use your iPhone connection while you're in Japan instead.
