Managing Your BIGLOBE Services and Account Details

Resolving Login Roadblocks to Your BIGLOBE Portal

⚠️ Forgotten BIGLOBE ID or Password

Cause: The user cannot recall their login credentials for the portal.

Solution: We know being locked out is stressful. If you cannot remember your BIGLOBE ID or BIGLOBE Password, utilize the dedicated reset links found on the login page. You will typically need to provide registered personal information, such as your name, date of birth, and registered phone number, for verification to securely regain access to your online account.

⚠️ Login Error Messages (e.g., 'ID or password incorrect', Error Codes 300, 104)

Cause: Incorrect entry of User ID or password, or input format issues.

Solution: If you encounter messages like "ユーザID(メールアドレス)またはBIGLOBEパスワードが正しくありません" (User ID/Email or BIGLOBE Password is incorrect) or specific error codes like 300 or 104, carefully re-enter your credentials. Double-check for typos, ensure you are using half-width characters (半角), and verify that your Caps Lock key is off. These often indicate simple input errors.

⚠️ Account Inactivity or Suspension (Error Codes 303, 304)

Cause: The BIGLOBE ID is either terminated, a service is temporarily suspended due to unpaid fees, or the ID is not associated with an active connection service.

Solution: An error code like 303 might indicate a suspended service due to unpaid fees. If this is the case, you will typically receive a postal notice requesting payment. Error code 304 suggests attempting to log in with a BIGLOBE ID that is not linked to a connected service. Address any outstanding payments or confirm your service status directly with BIGLOBE support.

⚠️ System Maintenance or Outage

Cause: Planned maintenance or an unexpected system failure is preventing login access.

Solution: Occasionally, login issues stem from planned system maintenance or unexpected outages. Before attempting extensive troubleshooting, check the official BIGLOBE support page (BIGLOBE会員サポート) or their social media channels for any announcements regarding service disruptions or maintenance schedules.

⚠️ Phone Authentication Issues

Cause: The registered phone number for authentication is incorrect, inactive, or not receiving the authentication request.

Solution: If a phone authentication request is not reaching you, it's crucial to ensure your registered phone number in the BIGLOBE system is current and active. Phone authentication is a security measure for sensitive operations, and an outdated number will prevent successful verification. Update your contact details through alternative verification methods if available.

Key Insights for BIGLOBE My Page Users

Q: How do I check my monthly usage fees and billing details?

You can view your detailed usage and billing statements by logging into your BIGLOBE My Page. Navigate to the "利用明細" (Usage Details) section to track your service consumption and payment history for various BIGLOBE services.

Q: What is the difference between a BIGLOBE Password and a Connection Password?

Your BIGLOBE Password is specifically for logging into your My Page and managing services like email and account settings. The Connection Password, however, is used to establish an internet connection on your devices, such as your modem or router. They are distinct credentials and should be managed separately for enhanced security.

Q: Can I log in to BIGLOBE My Page using my au ID?

Yes, if your BIGLOBE account is linked with an au ID and you are configured for KDDI billing, you can often use your au ID and its corresponding password to access the BIGLOBE My Page. Look for the au ID login option on the portal.

Q: What should I do if I suspect unauthorized access to my BIGLOBE account?

If you notice any unusual activity, immediately change your BIGLOBE Password to a strong, unique one. Subsequently, review your login history within the portal for unrecognized entries and check your usage details for any unauthorized service changes or purchases. Contact BIGLOBE customer support promptly to report the incident.

Q: How long can I access my usage details after canceling my BIGLOBE service?

Even after canceling your BIGLOBE service, you can typically access your usage details for up to eight months from the month following your cancellation date. You can do this by logging into the "利用明細" (Usage Details) page using your User ID. Be aware that the full My Page functionality may be limited after service termination.
