MoodSIM eSIM Data Plans for Japan

MoodSIM does not provide a true unlimited data eSIM for Japan. All plans labeled “Japan Unlimited” in MoodSIM’s catalog have a defined data cap—ranging from 500 MB to 10 GB per day—after which the connection is throttled to speeds such as 384 kbps, 512 kbps, 1 Mbps, or slower. Because the speed drops once the cap is reached, the plans are not unlimited in the sense of continuous high‑speed data.

Travelers who need larger and uninterrupted data volumes can choose one of MoodSIM’s fixed‑data plans. Examples include the Japan 20 GB 30 days plan priced at $12.49, the Japan 50 GB 30 days plan at $24.99, and the Japan 50 GB 180 days plan at $38.49. These fixed allowances can be more cost‑effective for heavy data users.

MoodSIM does not provide any Japan eSIM plan that includes a local phone number or SMS capability. All available plans from this provider are data‑only. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging.

MoodSIM offers a total of 91 data plans in Japan, split between single‑country and multi‑country options. Seven‑nine‑something single‑country plans cover Japan alone, while a larger set of 52 multi‑country plans that include Japan remain available. Prices vary from as low as $2.49 up to about $121.99, with data caps ranging from 500 MB to 50 GB and validity periods from one to 365 days. The plans are primarily fixed‑data bundles; no distinct daily‑data‑cap option is listed for this provider.
