mobineX eSIM Data Plans for Japan

MobineX’s devices in Japan use a name that reads “Unlimited, ” but all of the listed options have a specific data cap. For example, the 1‑day Unlimited Standard plan comes with 1GB of high‑speed data and then drops to a throttled speed of 128kbps once the limit is reached. Other “Unlimited” plans in the catalogue provide 5GB, 28GB, 42GB, 52GB, 65GB, 91GB, 169GB, or 169GB over the same period, all with a fixed amount of high‑speed data and no true unlimited bandwidth.

If an unrestricted data experience is desired, mobineX offers fixed‑data eSIMs that might be more economical for heavy users. Examples include the 100GB plan valid for 90 days, the 100GB plan valid for 180 days, and the 100GB plan valid for 365 days, all of which provide consistent high‑speed service throughout their validity without speed reductions. These options give travelers the flexibility to choose a plan that best fits their usage pattern.

MobineX does not offer Japan eSIM plans that provide a phone number or SMS capability. The only plans available from mobineX for Japan are data‑only eSIMs, without any voice or text messaging service.

Travelers wishing to communicate while in Japan can rely on VoIP applications such as WhatsApp, Telegram, and iMessage. These services use the data connection supplied by the eSIM, allowing calls and messaging without a traditional phone number or SMS ability.

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.
