mobineX eSIM Data Plans for Japan

mobineX does not provide a true unlimited data eSIM for Japan. All plans listed, even those that contain the word “Unlimited” in their name, come with a fixed data cap. For example, the longest‑validity plans are “Unlimited – 30 Days” with 169 GB, “Unlimited – 15 Days” with 91 GB, and “Unlimited – 10 Days” with 65 GB. These caps are applied for the entire validity period, and once the data is consumed the plan can be topped‑up or a new plan purchased.

Travelers who need a large amount of high‑speed data but still prefer a fixed‑price option will find mobineX’s high‑data plans such as the 100 GB‑90‑days or the 169 GB‑30‑days plans useful. Choosing a fixed‑data plan can be more economical unless one is an extremely heavy data user who might benefit from a truly unlimited service offered by other providers.

MobineX does not provide eSIM plans with a phone number or SMS for Japan. The provider sells only data‑only eSIMs, so travelers cannot receive inbound calls or texts via the Japanese mobile network. However, the data connection can be used for VoIP applications such as WhatsApp, Telegram, and iMessage, which allow calls and messaging without a traditional phone number.

mobineX offers 49 single‑country data plans and 116 multi‑country plans that include Japan. Prices vary from about $1.20 to $480.00, data caps range from 1 GB to 169 GB, and validity periods span from one day to one year. Single‑country plans provide a fixed amount of data for use only within Japan, whereas multi‑country plans typically give daily data limits to support usage across several countries during a trip.
