MoodSIM eSIM Data Plans for Japan

MoodSIM does not provide a truly unlimited high‑speed data eSIM for Japan. All plans labeled “Japan Unlimited” have a fixed data ceiling that ranges from 500MB to 10GB per day, after which the speed is throttled to between 256 kbps and 1 Mbps. Travelers who require a more predictable data allowance can select fixed‑data plans such as the 20GB 30‑day option or the 50GB 30‑day option, which offer higher volumes of high‑speed data with no throttling until the data limit is reached.

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.
