Additional High Speed Data

Data on our Japan SIM is fast, free and unlimited, you get 7GB of 4G LTE data. If you use more than 7GB, speeds drop to 128 kilobits per second, which is still good for most uses. There are no caps on the amount you can use, it’s completely unlimited!

On the first day of the calendar month, your data speeds refresh, so you get another 7GB of high speed data from the start of each new month.

However, sometimes, 7GB of high speed data just isn’t enough… If you find that you need more high speed data and you’re still a long way from the end of the month, simply contact us. We can add another GigaByte (GB) of high speed data to your SIM for just JPY ¥2,000. That extra 1GB can keep you going with streaming video, music, etc, etc, for just a little bit longer!

If you need an extra 1GB of high speed data, simply email us at including your Japan Phone Number. The additional data will be added to your account within 1 working day.
