Japan

Yes, as long as your iPhone is eSIM-capable and carrier-unlocked. That covers the iPhone XS, XR and every model since, so most travellers heading to Japan are ready to go. After you buy, we email a QR code; scan it in Settings to add the travel eSIM, then keep your normal SIM for calls and texts. Your existing number stays put on your primary line, while the eSIM carries your mobile internet in Japan. Turn roaming off on your home line so you are not charged, and let the eSIM handle data. If you are unsure whether your handset is unlocked, our 24/7 support can help you check before you fly to Tokyo or Osaka.

Yes. This Japan eSIM works on most recent eSIM-capable, carrier-unlocked Android phones, including the Samsung Galaxy S20 and newer, the Z Fold and Z Flip range, Google Pixel 3 and later, and many other current models. Setup mirrors iPhone: after purchase we email a QR code, you scan it to add the data plan, and you keep your usual SIM for your number. Switch off roaming on your home line and set the eSIM as your data line so it carries your mobile internet across Japan. If your model is older or you bought it locked to a carrier, eSIM support may be missing, so check your phone settings or ask our 24/7 team before you travel to be sure.

The Japan eSIM runs on the KDDI/au network, one of Japan's leading carriers, giving you fast 5G data where it is available and dependable 4G almost everywhere else. That means strong, consistent mobile internet in Tokyo, Osaka and Kyoto, plus reliable coverage on the Shinkansen routes and across major tourist areas. Because it is a trusted nationwide network, you can stream maps, book trains, translate menus and share photos without hunting for public Wi-Fi. This is a data-only travel eSIM, so calls and texts are not included, but apps like WhatsApp, FaceTime and iMessage work normally over the KDDI/au data connection. It is a clean alternative to a physical tourist SIM and to expensive roaming.

Very good. While Tokyo, Osaka and Kyoto get the fastest 5G, the KDDI/au network reaches far beyond the big cities, so your Japan eSIM keeps working in places most travellers actually go. Expect solid mobile internet around Mount Fuji, Hakone, Nara, Hiroshima and the Hokkaido and Okinawa tourist hubs, plus coverage along the Shinkansen lines and major expressways. In deep mountain valleys, remote hiking trails or rural stretches, speeds can dip to 4G or drop briefly, which is normal anywhere. For most sightseeing, navigation and ride bookings you will stay connected. If you plan serious backcountry travel, our 24/7 support can advise on coverage before you commit.

It takes a couple of minutes. After you buy, we email you a QR code. Connect to Wi-Fi, open your phone's settings, choose to add an eSIM or mobile plan, and scan that code to install the Japan travel eSIM. We recommend installing before you fly, while you have a stable connection at home. Your plan's validity and data do not start counting until the eSIM first connects to the KDDI/au network once you land, so installing early costs you nothing. When you arrive in Japan, set the eSIM as your data line, switch on data roaming for that line only, and you are online. Setup steps come with the email, and 24/7 support is on hand if anything looks different on your device.

Yes, and we recommend it. Install the eSIM at home using the QR code we email after purchase, while you are on stable Wi-Fi. Installing early does not start your plan: the validity period and data allowance only begin when the eSIM first connects to the KDDI/au network after you land in Japan. That means you can set everything up days before departure, then simply switch the eSIM on as your data line when you touch down at Narita, Haneda or Kansai airport and you are connected straight away. Doing this in advance avoids fiddling with settings while jet-lagged or hunting for airport Wi-Fi. If you would rather wait, you can also install once you arrive; either way our 24/7 support can walk you through it.

For most travellers, yes. Standard roaming charges from your home carrier can add up fast, often billed per day or per megabyte, and the cost is hard to predict. A Japan travel eSIM gives you a flat prepaid rate known upfront, with no roaming fees and no bill shock when you get home. You choose a data plan that suits your trip, and if you run low you simply add another plan or top up rather than overpaying for data you never use. There are no contracts and no surprise overage fees. Compared with both traditional roaming and queueing for a physical tourist SIM at the airport, an eSIM is usually the cheaper, simpler way to stay online across Japan.

It depends on how you travel. If you mostly use maps, messaging, train apps and occasional browsing, a lighter plan can comfortably cover a week in Japan. If you stream video, upload lots of photos and reels, video call home or rely on your phone as a hotspot, choose a larger allowance. As a rough guide, navigation around Tokyo and Kyoto plus social media uses modest data daily, while streaming and tethering can multiply that quickly. Many travellers find a mid-size plan ideal for a seven-day trip. The good news with this Japan eSIM is flexibility: start with a sensible plan, and if you run low you just top up with another plan instead of guessing high and overpaying upfront.

Yes to both. This is a data-only eSIM, so it does not give you a Japanese phone number, but it powers all your data apps. WhatsApp, FaceTime, iMessage, Messenger, Telegram and similar VoIP services work normally over the eSIM's mobile internet, so you can call and message friends and family while exploring Tokyo or Kyoto. Your usual number stays active on your primary SIM through your phone's dual-SIM setup, so you can still receive important texts or calls if you choose. To avoid home-carrier charges, switch off roaming on that primary line and let the Japan eSIM carry your data. That way you keep your number, dodge roaming fees, and stay reachable on the apps you already use.

Yes. Personal hotspot, also called tethering, is supported on this Japan eSIM, so you can share your connection with a laptop, tablet or a travel companion's phone. It is handy for getting work done from a Kyoto cafe, connecting a tablet on the Shinkansen, or keeping the whole group online from one plan. Just remember that anything you tether draws from the same data allowance, so streaming or large downloads on a second device will use your data faster. If you expect to hotspot a lot, pick a bigger plan from the start, and if you run low you can simply top up with another plan. Turn the hotspot off when you are not using it to make your prepaid data last longer.

The best eSIM for Japan is one that runs on a strong nationwide network, installs in minutes and has no surprise fees, which is exactly what this plan offers. It uses the KDDI/au network for fast 5G data in Tokyo, Osaka and Kyoto and reliable coverage well beyond, so your maps, translations and bookings just work. You activate instantly by scanning the QR code we email, keep your own number on your primary SIM, and enjoy a flat prepaid price with no roaming charges. Hotspot sharing is supported, top-ups are easy if you need more data, and 24/7 support has your back before and during the trip. For most tourists it is a cleaner, simpler choice than roaming or a physical SIM.
