How to set the message receipt report for LeTV mobile phone?

Letv mobile phone sets the SMS receipt reporting method as follows:

Click "Settings" on the desktop to enter the system settings page;

Click "Application Settings" in the lower right corner and select "Information" to enter the SMS Settings page;

The third column reminds and notifies "Send Report". You can choose whether to set SMS receipt or not, and click the check box.

I would like to remind you that the SMS function includes not only the settings of mobile phones, but also the communication gateways provided by some operators, so please do not change or delete the unconfirmed contents at will.
