Product Summary

So, you can easily navigate Japan with maps, transport information, translation apps, travel tips – and all-important social media – so you can keep the folks back at home up to date with just how amazing Japan is! If you use more than 4GB of data, your data will slow down for the remainder of the period. Unfortunately, it is not possible to top-up with more high-speed data.
