Troubleshooting: What to do when you don't receive your SMS verification code

Please confirm the following:

1. Verify your phone number entry
   • Ensure that you have entered your phone number correctly, including the country code(e.g., +81).
      
2. Confirm a stable network connection
   • Make sure your device is connected to a mobile data network or Wi-Fi.
   • SMS reception may be delayed in areas with a weak signal.
      
3. Confirm your device's SMS reception settings
   • The SMS may have been blocked as spam.
   • Verify your device settings to ensure that "Do not receive SMS" is not enabled.
   • For detailed instructions, please refer to your device's user manual.
      
4. SMS authentication may mot be available on some devices
   • Devices with data-only SIM cards or those without calling functionality (e.g., data-only tablets) cannot receive SMS messages.
      
5. If you still cannot receive the code after checking the above
   • You can register a GO account by verifying your identity.
