Precaution Statement for SIM Card Purchase

  • This SIM Card has an expiration date which is written on the package. Please start using it before the expiration date.
  • Actual speeds vary depending on location and connection status.


You can check your data balance online through our App (iOS , Android, and Web).

Our SIM card does not prohibit tethering (Personal Hotspot), so it should work.

It is the actual standard speed (not the theoretical figure) for travel SIM cards available on the market.

It's about 2 Mbps for both download and upload. It seems not that fast but fast enough for travel purposes. If you need faster speeds than that, we recommend you to rent our Pocket WiFi 4G or LTE plan .

Not necessarily. As long as your device is fully unlocked, there is a possibility that it will work. If in case it does not work, we can provide you alternatives such as:

  1. Upgrade to any of our Pocket WiFi plans (the price difference will be charged).

  2. Provide our mobile router to use the SIM (the shipping fee will be charged).

No, it does not work outside of Japan.
