On the profile page, click the '**Security**' option and select '**Mobile**'.
Similar to binding a mobile phone number, we highly recommend using Telegram to receive the verification code, as it is more stable.
If you insist on using SMS to receive the verification code, you need to click the '**other options**' button.
Click the '**send code**' button, and you will receive the code from your SMS or Telegram account. Once it has been confirmed, your phone number has been changed successfully. --- # Agent Instructions This documentation is published with GitBook.
