🅰️ 3-in-1 SIM cards (nano, micro, standard).

Be sure to handle the IC chip carefully when removing it to avoid damaging it.

🅰️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.

🅰️You will not be disconnected within the validity period and can use the internet with a speed of 200kbps indefinitely.
High-speed data can be added as needed. 👉【eSIM/SIM】Recharge
