MoodSIM eSIM Data Plans for Japan

MoodSIM does not provide a truly unlimited data eSIM for Japan. The plans that carry the name “Japan Unlimited” actually offer a finite amount of high‑speed data, such as 1 GB or 2 GB, after which the speed drops to a reduced rate. Travelers who need more data can choose one of MoodSIM’s fixed‑data plans, which include options such as Japan 50 GB for 30 days at $24.99 or Japan 20 GB for 30 days at $12.49. These plans give a large, flat data allowance without the throttling that applies to the “Unlimited” named plans, making them a more economical choice for most users who do not require an ongoing unlimited data supply.

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 provides a total of 41 single‑country data plans that cover Japan, and an additional 58 multi‑country plans that include Japan as part of their coverage area. The single‑country plans range in price from approximately $2.49 to $121.99 and offer data caps between 500 MB and 50 GB. The multi‑country plans feature a similar price range and data cap range, with durations varying from 1 to 365 days. Some plans allow tethering, while others reduce speed to specified lower limits. Both categories give travelers flexibility depending on the amount of data needed and the length of stay.
