Can oppo mobile phone send short messages regularly?

Early OPPO models all had the function of sending messages at regular intervals, such as OPPO R8 17 mobile phones. Enter the message, edit the message, enter the recipient, click the three dot icons in the upper right corner, and you can choose to send the short message regularly. The latest OPPO models have no regular SMS function and should be cancelled.

This answer applies to all OPPO models.
