Why didn't you send a text message when you issued the invoice?

Unicom users can download and log in to Unicom APP, click the menu "Service-Inquiry-Electronic Invoice", and the issued invoice is in the column of "Invoiced". Find the invoice that needs to be sent again, click "Push Mail", fill in the mailbox and send it to the mailbox.
