 5. Add signature and template following the guidelines, and provide the materials or information required for review.
     - Remember to select "Verification Code Message" (验证码) as "Scenario" (适用场景) when filling out the signature application and also "Verification Code Message" (验证码) for "Type" (模板类型) when applying for a template review because we are using these signatures and templates to send passcode. Currently, we do not support sending SMS messages other than verification-code-related text messages.
     - Also, use `{{code}}` as a placeholder where you want to place your digital passcode in template contents.
 6. After submitting your SMS signature and template application, you need to wait for it to take effect. At this point, we can go back to the [SMS service console page](https://dysms.console.aliyun.com/overview) and send a test SMS. If your signatures and templates are ready for use, you can try them directly; if they are not taking effect yet, Aliyun also provides test templates.
     - You may need to recharge a small amount of money before sending test messages.
-    - You may also be asked to bind a test phone number before sending test messages. For more details, go to "Quick start" (快速学习) tab from the sidebar of the [SMS service console page](https://dysms.console.aliyun.com/overview).
