🅰️ 3-in-1 SIM cards (nano, micro, standard).
There are notches around the IC chip for nano, micro, and standard sizes. Use your finger to push out the required size from the back.
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

① When You Receive Your SIM Card

Simply insert the SIM card into your phone to start using:
📞 Voice Calls
📨 SMS

✔ Wi-Fi and Mobile Data settings do not affect voice or SMS service.

② Do NOT Configure APN Outside Japan (Important)

❌ iPhone: No configuration profile is required.
❌ Android: No APN setup is required.

📍 APN settings are only required when using mobile data (1–50GB) in Japan.

③ Dual SIM Settings

If your phone has two SIM cards:

✔ Select the SIM you want to use for mobile data.
✔ It is recommended to turn off Automatic Mobile Data Switching.

👉 This prevents your phone from switching to the SIM that cannot access the internet.

④ If the SIM Doesn’t Work

Please try the following first:

1️⃣ Update your phone to the latest system version (VoLTE support is required).
2️⃣ Remove any APN settings (do not configure APN outside Japan).
3️⃣ Turn Airplane Mode on and off to reconnect to the network.
4️⃣ Restart your phone.

⑤ Still Not Working?

👉 Please test the SIM card in another phone (your spare phone or a friend’s phone).

✔ Works in another phone → The issue is with your phone settings.
✔ Doesn’t work in any phone → The SIM card may be defective (we can arrange a replacement).
✔ If the issue is due to device compatibility → We can assist with a return or refund.

🅰️Our eSIM uses the local docomo mobile network in Japan, so it can only receive the signal after entering Japan. Once the signal is received, it will automatically activate immediately.

【Note】Most of the eSIMs currently available on the market are international roaming eSIMs sold by telecom companies from various countries in Taiwan. This is why they can be set up before traveling abroad, and you need to turn off roaming while outside Japan and enable international roaming after arriving in Japan. Since our eSIM is a local product for Japan, you do not need to enable roaming.

🅰️Yes, it can be done.
When adding eSIM outside Japan, it will not be fully activated. The screen will stay on “Activating…”.
Once you arrive in Japan and receive the docomo signal, it will automatically activate successfully.
