Preparing for Your My SoftBank Account Access

Connecting to Your My SoftBank Digital Portal

  1. Navigate to the official My SoftBank website using your preferred browser. The main login page is accessible at my.softbank.jp.
  2. If you are using a SoftBank smartphone connected to their mobile network, turn off your Wi-Fi connection. This enables an automatic login feature, often requiring no ID or password entry.
  3. For logins via PC or if Wi-Fi is on, enter your SoftBank ID (which could be your mobile number) and your password into the designated fields. Then, select the "Login" button to proceed into your user dashboard.
  4. Some actions within My SoftBank, especially those involving sensitive information, may require a security number. This three-digit code will be sent to your registered mobile phone via SMS from "157". Enter this code on the My SoftBank screen to verify your identity.

Exploring Your My SoftBank Account Services

When Access to My SoftBank Isn't Working

โš ๏ธ Cannot log in to My SoftBank

Cause: Several factors can prevent access, including active Wi-Fi or VPN, incorrect SoftBank ID/password, maintenance, or recent contract changes.

Solution: First, turn off your Wi-Fi if you are trying to log in using a SoftBank mobile connection, as this enables automatic authentication. If a VPN is active, turn it off temporarily, as it can interfere with the login process. Clear your browser's cache and cookies, or try a different browser. If the issue persists, verify that your SoftBank ID and password are correct. For issues with the My SoftBank app, try using the web version as an alternative.

โš ๏ธ Forgot SoftBank ID or password

Cause: You cannot recall your SoftBank ID or password.

Solution: The My SoftBank portal provides a recovery process. You can often retrieve your SoftBank ID or reset your password by providing your mobile phone number and a 4-digit security code (ๆš—่จผ็•ชๅท). A verification code will then be sent to your phone via SMS to complete the process.

โš ๏ธ Account is locked or authentication error

Cause: Entering an incorrect password multiple times can temporarily lock your account. Security numbers may also be entered incorrectly.

Solution: If your account is locked, you may need to wait for a specific period before attempting to log in again. Ensure you are entering the correct 3-digit security number sent via SMS; sometimes other numbers in the message can be confusing. Clearing browser data might also resolve persistent authentication errors.

โš ๏ธ Cannot log in after contract cancellation or name change

Cause: After canceling your SoftBank contract or changing the name on your account, the login method or accessibility may change.

Solution: After cancellation, you might need to use your SoftBank ID and password, as automatic login via mobile line information will no longer work. Be aware that My SoftBank access may be limited after 91 days post-cancellation. For name changes, allow a few days for the system to update before attempting to log in again.

Q: What is the security number for in My SoftBank?

The security number is a 3-digit code sent to your mobile phone via SMS from "157" when you access sensitive information or make changes in My SoftBank. It serves as a verification step to prevent unauthorized access.

Q: Can I use the My SoftBank app on Wi-Fi?

To automatically log in to the My SoftBank app when using a SoftBank mobile line, you generally need to turn off Wi-Fi. If Wi-Fi is on, the app might not be able to verify your identity via the mobile network, leading to login difficulties.

Q: What can I do if My SoftBank shows an 'authentication error'?

If you encounter an authentication error, try clearing your browser's history, cache, and cookies. Rebooting your device or attempting to log in from a different browser might also resolve the issue. Ensure your Wi-Fi and VPN are off if using a SoftBank mobile connection.
