BambooSIM eSIM Data Plans for Japan

BambooSIM provides unlimited‑data eSIM plans for Japan. The plans are available in 5G coverage and range from 3 days to 31 days, with prices spanning $9.95 up to $68.29. All unlimited plans allow tethering and are marked as fully unlimited.

Even though the data cap is labeled “unlimited, ” BambooSIM applies a Fair Usage Policy. After heavy usage, speeds may be reduced, so travelers concerned about potential speed restrictions should contact BambooSIM directly to confirm whether the FUP applies and the expected threshold for maintaining normal 5G speed.

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.
