Data SIM and eSim

If you want to be always connected to the Internet with your smartphone without spending a fortune, in Japan there is the possibility of buying prepaid SIM cards with data traffic. You can buy the data SIM before you leave and have it sent to your home. You can book it online and pick it up directly at the airport or hotel in Japan, or (more expensive solution), buy it directly on the spot (airport, electronic shops such as BIC Camera or Yamada Denki). Below you will find descriptions of SIM cards offered by various telephone companies or travel agencies.

Before buying a SIM card, check that it is supported by your smartphone or tablet.

A good alternative is to buy an eSim. If your smartphone does not have an eSim built-in, you can buy a sim that can make your smartphone eSim-compatible. Click here to learn more about
