What does it mean that Alibaba Cloud SMS parameters are not set?

This means that there are no parameters set in your SMS settings.

If it is used for your own products, such as sending balance reminders to users, that's fine, but if it is commercial promotion, there may be problems if it is sent too much, but you can direct users to your own webpage for publicity by sending links.

If the mobile phone wants to prompt the setting of SMS in the background, you should set it in the mobile phone. The setting of the background can be well designed. If the design is not good, go to the mobile phone shop and ask him to give it to you.
