Frequently asked questions
How much data should you choose?
For maps, messaging and light browsing, a few GB are usually enough on a short trip. For social media, video, remote work or video calls, go for a larger allowance.
Can I keep my usual number?
Yes. On a Dual SIM compatible phone you keep your usual line for calls and texts, and use the Décall eSIM for mobile data.
Is my phone compatible?
eSIM works on recent eSIM-compatible smartphones that are not carrier-locked. If you are unsure about your model, message us before buying.
What to know before landing in Japan
Japan has the densest network in the region: NTT docomo covers 99.9% of the population, and all four national operators run 5G. The thing to watch is not coverage but which network you land on: Rakuten Mobile remains thinner in rural areas, where it leans on KDDI roaming.
On the ground
- •Networks used: NTT docomo, KDDI/au, SoftBank and Rakuten Mobile, all on 5G.
- •Coverage is continuous on trains, including the Shinkansen, and in the Tokyo and Osaka metros.
- •docomo does not issue prepaid cards under its own name: tourist SIMs go through resellers.
Which plan for a stay in Japan
For two weeks across Tokyo, Kyoto and Osaka, 10 GB covers maps, live translation and bookings. If you tether for several people, take 20 GB.
Does the eSIM work on the Shinkansen?
Yes. High-speed lines are covered by the partner networks, with brief drops in some tunnels.
Can I use Google Maps and translation offline?
With the eSIM you stay connected, so online. Downloading the city map before you leave is still a good habit in case of a drop.
