Frequently asked questions
How much is the 20 GB, 30-day Japan eSIM?
This plan is $15.58 USD for 20 GB valid for 30 days in Japan, delivered instantly by QR code.
Is 20 GB enough for 30 days in Japan?
20 GB suits light daily use: maps, messaging and occasional browsing. For heavy streaming or hotspot use, pick a larger plan, or top up mid-trip.
Which networks does a Japan eSIM use?
SimKit Japan eSIMs connect to NTT docomo, Rakuten Mobile and KDDI/au, with 5G available where the network supports it. You get the same coverage as a local SIM without swapping anything physical.
Is the Japan eSIM 5G?
Yes. Where Japan's networks offer 5G, SimKit eSIMs use it, falling back to 4G/LTE elsewhere. Speeds depend on your device and local coverage.
How do I install and activate a Japan eSIM?
After you buy, SimKit shows a QR code. Scan it in your phone's cellular settings (or install it straight from the SimKit app) and the eSIM is ready, typically in under two minutes. Activate it when you arrive in Japan.
When should I buy a Japan eSIM?
Any time before you travel. The plan's validity only starts when the eSIM first connects to a network in Japan, so you can buy as soon as you book, install on Wi-Fi at home, and it activates when you land.
