Is there any software that allows others to send text messages when they can't see them?

Download management software 360, security housekeeper, mobile phone housekeeper and other management software. Set it to only receive the white list (if it is for one or several people, set it to only block the blacklist, and then add his/her number to the blacklist), and then set it to not prompt or display the background icon during interception. Now set the program as the startup password. If you want to see it, enter the password into the interception record so that others can't see it.

If you just want to be private, set up a private mailbox. These softwares support it. Add a private contact, and then set a password on the private mailbox. SMS/phone can be set as a private mailbox. It can't be found in local mailboxes and records, but can only be seen through software.
