MobineX does not have a true unlimited data eSIM plan for Japan. Every plan that uses âUnlimitedâ in its name actually contains a data cap, ranging from 1GB to 169GB, and after the cap is reached the speed is throttled to a lower rate.
If a traveler needs a large allocation of highâspeed data, mobineX offers fixed data plans such as 100GB for 90 days, 100GB for 180 days, or 100GB for 365 days, all available on 5G (and some on 4G/LTE). These fixedâdata options can be more costâeffective for users who consume a substantial amount of data during their stay.
