Frequently asked questions
Can I make phone calls using ESIMJAPAN.com?

How is the coverage in rural areas?
Access to Japan’s KDDI network makes coverage generally good across Japan, including many rural areas. However, extremely remote locations might have limited service.
Can I top up if I run out of data?
Yes, if you’ve purchased a fixed-data plan, a top-up option is available.
Can I share my ESIMJAPAN.com eSIM between devices?
No, each eSIM is tied to a single device. You’ll need to purchase separate plans for additional devices. Alternatively, if you’re traveling with family or a small group, consider renting a pocket WiFi device to share.
Can I use tethering/hotspot with ESIMJAPAN.com’s eSIMs?
Tethering is possible if your device or network supports it. In some cases, you might need to update your device’s APN settings. ESIMJAPAN.com’s website recommends sharing data to other mobile devices instead of laptops for the best speeds.
