Cellesim for Japan FAQ

Does Cellesim offer unlimited data eSIM for Japan?

Cellesim does not provide an unlimited data eSIM plan for Japan. The available options are fixed data plans that come with a set data cap and a defined validity period. Examples include the Japan 50GB 30d plan, the Japan 50GB 180d plan, the Japan 20GB 30d plan, the Japan 10GB 30d plan, and the Japan 5GB 30d plan.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from an unlimited plan.

Cellesim does not offer any Japan eSIM plan that includes a phone number or SMS capability. All available plans are data only. Travelers who want voice or messaging in Japan can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Japan before purchasing the plan.
