Your Concerns, Answered

eSIM plans for Japan: by gigabytes or unlimited, which is better?

One of the strengths of the eSIM is flexibility. That is why we recommend choosing prepaid by gigabytes when you travel for a few days and unlimited plans when you are there for a longer time or need to work in Japan.

Prepaid data packages

Options from a few GB to packages of several weeks. Perfect if you only use maps, WhatsApp, or social networks.

Unlimited planes and fair use policies (PUJ)

Unlimited plans work very well, but be careful: almost all providers apply a fair use policy (FUP), which means that the speed may be reduced if you consume too much in a short time. This will be clarified in the description of each product.

Share internet with hotspot in Japan

If for your business trips you usually need the laptop. With our eSIMs from Japan, you simply activate the hotspot and share your data as if you were carrying a pocket WiFi, but without carrying another device.

Coverage and speed in Japan

Network coverage is key in Japan, especially if you plan to travel outside the major cities.

Premium operators: KDDI, SoftBank, and Docomo

The best eSIMs connect to leading networks like KDDI, SoftBank, or Docomo. These have been tested and the signal is very stable even on bullet train journeys.

5G Connection: what to expect in Tokyo, Kyoto, and Osaka

In Tokyo and Osaka, I managed to navigate with 5G speed, perfect for video calls or uploading content on social media without interruptions.

Differences between eSIM for Japan and eSIM Asia

eSIM Japan: designed only for this country, with better local coverage. eSIM Asia: includes several countries, ideal if you plan to travel to Korea, China, or Thailand.

Compatibility and Dual SIM

Before buying, the first thing is to check if your phone supports eSIM. In general, iPhones from the XS onwards and many high-end Androids are already compatible. Check out our complete guide to compatible devices with eSIM.

Use your usual number along with the eSIM Japan

Something that our users love is that you can use Dual SIM: you keep your usual number for calls and WhatsApp, and at the same time, you use the eSIM for data in Japan. You don't need a second device or to lose your line.
