Prepaid mobile data for Japan with instant activation and no roaming bill surprises. From $1.40 USD.
A simple guide to compatibility, setup, calling, and a few important details that help your eSIM work smoothly from the start.
Our eSIM plans give you fast mobile data without a physical SIM card. After purchase, you can install your eSIM by scanning a QR code or using direct install from the eSIMstep app.
Most newer iPhone, Samsung Galaxy, Google Pixel, Motorola, Xiaomi, Huawei, and other modern devices support eSIM.
Open the eSIMstep app and use our eSIM compatibility detector to check your device instantly.
Keep your main SIM active if you want to continue receiving calls or SMS on your regular number.
Your phone may show a carrier or profile name such as Orange France during installation. This is normal and does not mean you bought the wrong plan. Some eSIMs use international network profiles and local roaming partners. Your plan will work in the destination listed on your order once installed correctly and data roaming is enabled.
Calling is available through the eSIMstep app on iPhone and Android. The eSIM itself provides mobile data, while outbound calls are made inside the app over WiFi or mobile data.
This is useful when you need to call hotels, taxis, restaurants, airlines, or local businesses while traveling. Selected plans may include free calling minutes, and you can also buy calling credit inside your account.
Eligible eSIM plans include VPN access. Use it to browse more privately, protect your connection on public WiFi, and access your usual apps while traveling.
Calling and VPN features work through the eSIMstep app.
When installing your eSIM, your phone may show a different carrier or profile name, such as Orange France, even if you purchased a plan for another destination.
This is normal. eSIM plans can use international carrier profiles and roaming partner networks. The displayed name does not always match the country you selected.
If your eSIM does not connect after installation, contact eSIMstep support before deleting the eSIM from your device.
Yes. eSIMstep offers prepaid eSIM data plans for Japan. Coverage depends on the selected plan, your device, and local network availability.
Your Japan eSIM may connect to supported local networks such as KDDI, KDDI/au 5G, NTT docomo 4G, NTT docomo 5G, depending on the selected plan and local availability.
5G is available where supported by the selected plan, your device, and the local network. Otherwise, your device may connect on 4G/LTE.
Most travel eSIM plans are data-only unless the plan specifically states calls or SMS are included. eSIMstep Calling can be used separately through the app where available.
Hotspot is available when supported by your device and selected plan. Some carriers or plans may apply local restrictions.
We recommend installing your eSIM before your trip while you have stable WiFi. Turn on the eSIM line and data roaming when you arrive at your destination.
Country plans first, then regional, global, and unlimited when available.

eSIMstep is operated from New Westminster, BC, Canada. Customers can contact support for installation help, refund questions, and account issues before deleting an eSIM from their device.
Your high-speed data allowance is used first. Once it runs out, your connection is NOT cut off. Instead, your speed is reduced to 1 Mbps, which is sufficient for basic tasks like messaging and light browsing.
Daily unlimited plans can be extended before the eSIM expires. After the validity ends, the eSIM cannot be topped up and a new eSIM is required.
Your internet traffic is NOT routed through Hong Kong servers, which would otherwise cause higher latency and slower speeds.
This means lower ping and a faster, more stable connection for video calls, streaming, and real-time apps.
You are assigned a US IP address regardless of your physical location.
This allows you to bypass geographic restrictions and access US-only services such as banking apps, streaming platforms, and region-locked websites from anywhere in the world.
Eligible plans receive free calling minutes based on the plan price.
Due to their digital nature, eSIM profiles are generally non-refundable once delivered or activated.
Eligible for Refund (within 48 hours):
