BambooSIM eSIM Data Plans for Japan

BambooSIM offers a range of unlimited data eSIM plans for Japan, with validity periods from 3 days up to 31 days. Prices start at $9.95 USD for a 3‑day plan and rise to $68.29 USD for a 31‑day plan, all delivered over 5G networks and allowing tethering.

Even though the data cap is listed as unlimited, BambooSIM applies a Fair Usage Policy. After a certain amount of high‑volume use, speeds may be reduced to a lower tier. If you anticipate heavy data consumption or want assurance about how long normal speed will last, contact BambooSIM directly to confirm the typical data volume that remains at full speed under the FUP.

BambooSIM does not provide a Japan eSIM that comes with a phone number or SMS capability. The provider offers only data‑only plans for travel in Japan.

Travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make voice calls and send messages.

BambooSIM lists a substantial portfolio of data plans that include coverage for Japan. The provider’s catalog contains 46 single‑coverage plans that support individual countries and 26 multi‑coverage plans that span several destinations, including Japan. While the exact number of those plans that are specifically priced or tailored just for Japan isn’t broken out in the data, the broad range spans data caps from 1 GB up to unlimited and prices from $0.99 to $68.29, with validity periods between 3 and 31 days. These plans also offer the possibility of tethering on some options.
