For SIM cards, you will not be able to check the usage since they are unlimited SIM cards for travel use.

NOTE:

※To manage network resources, unlimited data plans are managed by a Fair Usage Policy (FUP). In wireless internet services, unlimited data means you will not be disconnected based on your usage or the amount of data transferred.

We do our best to provide our customers with large amounts of data that they can comfortably use while in Japan. However, depending on the carrier’s decision, the overuse of mobile communication will affect the usage of other customers and may be deemed as irregular usage. 

※The TRAVEL SIM card is designed to be used by travelers and does not support long-term video streaming, video-conferencing/calling for extended periods of time, or downloading large amounts of data. If you plan on using the SIM cards for such purposes, please contact us.
