Why send text messages to show delivery?

To sum up the above problems: first, you can take the owner's ID card and password to the mobile business hall to print the list and see if there are any records and expenses generated by sending this short message, so as to judge whether this short message is really sent; If there is a charge, ask for proof of movement and check whether there is any software installed on your mobile phone that will cause you to send SMS automatically. Secondly, if the above processing does not show the expenses on the list, it can be judged that it is only displayed on the mobile phone, and it has no actual impact on you (money). You can check it with your mobile phone. Pay special attention to some old second-hand mobile phones, and there are some opportunities for knockoffs. I hope I can solve your problem, thank you!
