MoodSIM eSIM Data Plans for Japan

MoodSIM does not provide a genuinely unlimited data eSIM for Japan. All plans listed under the “unlimited” label contain a fixed data allowance that is applied daily; once the daily cap is reached the connection speed is throttled to a lower rate (for example 384 kbps or 512 kbps).

If a traveler needs a larger, unthrottled data envelope, MoodSIM offers fixed data plans such as the Japan 50 GB 30 days or Japan 20 GB 30 days options, and even a Japan 50 GB 180 days eSIM. These plans give a set amount of high‑speed data for a specified validity period and may be more cost‑effective than the “unlimited” plans for heavy data users.

No, MoodSIM’s Japan eSIM plans do not provide a phone number or SMS capability. The provider only offers data‑only plans for Japan, so travelers can use the internet connection to run VoIP applications such as WhatsApp, Telegram or iMessage for voice calls and messaging, but they should confirm that those services are accessible in Japan beforehand.

MoodSIM provides 41 single‑country plans that cover Japan, and 58 multi‑country plans that include Japan. Most of the plans are fixed‑data amount plans, with data caps ranging from 500 MB up to 50 GB. Prices for these plans fall between roughly $2.49 and $121.99, giving customers a broad range of options for their stay.
