Is it possible to extend the validity period of the eSIM or add more data?

🅰️All eSIMs can have their validity period extended or additional high-speed data added.

  • You can top up or extend within the validity period.
  • Remaining data and newly added data are treated the same; there is no usage priority between the two.
  • There is no limit to the number of top-ups or extensions.
  • If you top up within 7 days after the expiration date, the data balance will be reset to zero, but you can continue using the original eSIM or SIM card.
  • The extension period is calculated from the 2nd day after the original expiration date, which is considered the first day of the new validity period.
  • After purchase, in addition to receiving an email with an electronic receipt, you will also receive a separate activation notice from our company via biz@jbrg.jp.
  • You may request a cancellation before receiving the activation notice. However, a 5% processing fee will be deducted to cover credit card company fees.
  • If you apply for an extension after 6:00 PM on the last day of validity, please contact customer service for confirmation before making the purchase to avoid delays in processing.
  • After the initial validity period ends, the online inquiry system [eSIM Activation URL] will no longer reflect the extended validity or remaining data. Please use your mobile device’s data usage statistics instead.
  • All JBeSIM plans are eligible for top-up and extension. JB SIM cards with data capacity (X-GB) can be topped up, while time-based plans (6/8/16/31 unlimited) cannot be extended.
