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.

MoodSIM does not provide a Japan eSIM that includes a phone number or SMS capability. All plans sold by MoodSIM for Japan are data‑only, so travelers will not receive an active phone number for voice calls or text messages. If you need to stay in touch, popular VoIP applications such as WhatsApp, Telegram and iMessage will work over the data connection and let you make calls and send messages without a local phone number.

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.
