Japan eSIM

As fast as the local network is at that spot, which is the same connection residents get. Plans that carry 5G say so on the row, and fall back to 4G where 5G has not reached. Congestion, buildings and your own phone all move it, so no eSIM can promise a number. Each unlimited plan states its own terms on its row, whether that is a daily full-speed allowance, a speed cap or no cap.

Install it at home over Wi-Fi, on an unlocked phone that supports eSIM. The validity clock does not start until the eSIM first connects to a Japanese network, so setting it up days early costs you nothing. On arrival, select it for mobile data. Narita publishes counter locations and individual opening hours for SIM sales and Wi-Fi rental; check your terminal if that is your backup. Japan's major international airports also provide free terminal Wi-Fi.

Japan's tourism board lists airport SIM sales and pocket Wi-Fi rental among the alternatives to a travel eSIM. A physical SIM needs an unlocked phone with a suitable SIM slot. Pocket Wi-Fi can suit a group staying together or devices without eSIM support, but adds a router to charge and return under the rental company's terms. An eSIM is installed on your compatible phone. Check its hotspot rules before expecting it to connect a laptop or another traveller's phone.

Not on the SimFuse plan. You pay once, upfront, and nothing arrives afterwards. Your home SIM bills by its own tariff: if that tariff includes Japan, as Roam Like at Home does for EU and EEA home SIMs inside the EU and EEA (within fair use), it costs what it does at home. If not, it bills at your carrier's roaming rate, so turn off data roaming and automatic data switching before you land.

No. The plans listed here are data only, with no call or SMS allowance. You can use calling and messaging apps over data.

No. Compare your home carrier's roaming, a local SIM and pocket Wi-Fi with a travel eSIM. Your phone must support the option you choose. An eSIM has no rental router to collect or return.

Japan eSIM plans from SimFuse start at EUR 3.29. Compare the live plan prices with their data and validity. Charges from your home SIM are separate, so check its roaming settings before travelling.

An eSIM is a digital SIM installed on a compatible, unlocked phone. Follow the selected plan's activation instructions and choose it for mobile data in Japan. On a supported dual-SIM phone, your home line can remain available, subject to its own charges.

An eSIM suits a compatible phone without a separate router to carry. Pocket Wi-Fi can suit several devices travelling together or a phone without eSIM support. Compare the total rental cost and return rules with an eSIM's hotspot allowance.

Only if your selected plan explicitly includes a Japanese number. Data-only plans do not include one. If a plan includes calls or texts, check the number's country and its allowances before relying on it for bookings or SMS verification.

Yes, on plans that allow tethering, and each plan row says which do. If the row shows a separate tethering cap, the laptop is limited to that amount. If not, it draws on the same data your phone does. On an unlimited plan, the row also states what unlimited means there.

Japan eSIM plans from SimFuse start at EUR 3.29. Pick on three things: the data you use in a day, how long you stay, and whether you need to tether. Compare validity and allowance terms below. Use Advanced filters to check the available networks.

Japan plans run on KDDI, SoftBank, and Rakuten. Carriers differ between plans. Use Advanced filters to check available networks. Your phone shows the local carrier's name in its status bar. An unstated generation is not a promise of 4G or 5G.

Keep it if you want your existing number reachable for calls and texts. On a dual-SIM phone, your home SIM and travel eSIM sit side by side. Calls and SMS included with your travel plan use its own line. Turn off data roaming and automatic data switching on your home line to control its roaming use.

Check your exact model and regional version in the compatibility guide, then look for 'Add eSIM' in your phone's settings. The phone also has to be carrier-unlocked. Brand and release year are not enough on their own, because some regional versions of an eSIM-capable model ship without it. Check your exact phone model →

Some plans stop until you top up, others continue at a reduced speed, and each plan row says which. A top-up adds data to the eSIM you already have. Each top-up option states its own validity and says if it replaces your current plan.

Yes, within 30 days of purchase, while the eSIM is unused. One that has never connected and has used no data is refunded in full, including when your phone turns out not to support eSIM or you could not get a connection at all. Once it has connected and carried data, contact support and we will look at it.
