  • Mobile Plan Short FAQ

    Mobile Plan Short FAQ

    1. What do I need to signup ?
      You will need a picture or scan of either your passport (Japan’s visa page), your Residence Card or your Military ID.
    2. It is the end of the month, do I have to pay for the whole current month if I signup ?
      If you signup after the 23rd of the month, we will not charge you at the end of the month.
      Instead, your first renewal payment will be at the end of the next month.
      Your subscription will be updated and the new renewal date will show on your Account.
    3. How soon can I get my Mobile Plan SIM card ?
      You can select to pick it up on the same day at our office. Usual shipping in Japan takes 2 to 4 days.
    4. Can I signup now even if I come to Japan later in the future ?
      Yes! As long as you know where to receive your SIM, you can add in the order notes your date of arrival.
      We will not charge you anything until you actually arrive in Japan.
      For example: You want to subscribe in August but arrive in October, then your first renewal will be at the end of October!
    5. Can I update my payment info and switch credit cards online ?
      Yes you can do it from your Account under the Payment Methods section.
