Destination briefing
Good to know in Japan
Tokyo, Kyoto and Osaka have extensive mobile service, but indoor, underground and 5G availability still varies by plan, device and location.
On intercity rail and rural routes, service can change through tunnels and remote stretches. Download essential maps before departure.
Maps, messaging and transit apps use far less data than video or hotspot sharing. Choose the allowance around your heaviest activity.

Japan-specific questions
FAQ
- Selected plans use supported local network routes such as NTT Docomo or SoftBank. Coverage and radio type vary by plan, location, device, congestion and local network conditions, especially underground, in tunnels and in remote areas.
- For maps, messaging and transit checks, 500 MB to 1 GB per day is a practical starting range. Choose 2 GB per day, a larger total-data pack or Unlimited if you expect frequent video, uploads or hotspot use.
- Unlimited means the plan continues to provide data, but full-speed use can be subject to a fair-use threshold. The selected plan shows its high-speed allowance and post-limit speed before checkout.
- 5G may be available when the selected plan, device, location, and local network all support it. The phone may fall back to 4G LTE as conditions change.
- Yes. Our eSIM is your second line for data only — your home SIM keeps receiving calls and SMS. You just route data through the Japan line in Settings → Cellular.
- Validity normally starts when the eSIM first connects to a supported network, not when you purchase it. Install before departure on Wi-Fi, then enable the Japan line and data roaming after landing.
