Lumbus eSIM Data Plans for Japan

Lumbus does not provide a truly unlimited data eSIM for Japan. The plans that carry the name “Japan Unlimited” give a maximum of 3 GB of high‑speed data each day; after that amount the plan stops providing additional data, so the service is not truly unlimited.

Instead, Lumbus offers fixed‑data plans that may better suit travelers who need a larger data allowance. For example, a 50 GB plan for 30 days costs $34.99 USD, and a 20 GB plan for 30 days costs $16.99 USD. These fixed plans give larger totals than the daily caps on the Japan Unlimited plans and can be more cost‑effective for users who consume moderate to large amounts of data.

Lumbus does not provide a Japan eSIM that includes a phone number or SMS capability. The company offers only data‑only eSIM plans for Japan. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but should verify that these services are accessible in Japan before purchasing, as some destinations may block or restrict specific apps.

Japan is covered by Lumbus, which offers 14 single‑country plans and 46 multi‑country plans that include Japan. Each plan ranges in price from $1.99 to $179.99, with data caps spanning from 500 MB to 50 GB and validity from 1 to 365 days. In addition to fixed data cap options, Lumbus also provides daily data cap plans, which grant a specified amount of data each day for the duration of the plan.
