How can I oops back a sent text message?

[Valerie4838]

I sent a text message on my android LG V30 phone using the yellow text messaging icon which came with the phone via tmobile. It may be an older google txt message app because I cant find it in playstore anymore. Anyway, I dont want the person to read it now. Is there any app that would allow me to undo this message? I think not but thought Id ask anyway. They did not read it yet. If they do I'll be in a lot of trouble. Thanks a lot folks

You don't. It's impossible because of how the way SMS works. If it's sent, it's sent.
