How do I access my child's text messages?

Try talking to my child? Don't you think I've already done that?🙄

Here's a little background on me: I'm a disabled Veteran who's been a "stay-at-home" Dad from day one of my daughter's life. I'm the one who cared for her as an infant, feeding her, clothing her, reading to her, playing games with her, walking her to and from school every single day (from kindergarten to 5th grade)-all the things a good Dad can and should do.

As for my daughter, she's our only child (my wife suffered a miscarriage and we lost our son) but she's everything to me. She's a beautiful young girl (she's 13 now), very intelligent and creative, loves music, she's learning another language, and she's an incredibly gifted artist. She loves to play Minecraft, Overwatch, and other video games. She's well-liked by her friends, who have all been friends since the first grade of school. My wife and I have always given her everything she's needed or wanted (within reason), so she's never lacked material things, etc. She's a good kid, and I've never known her to be dishonest about anything.

I don't feel I need to divulge anything more here than I have, nor do I need to justify myself to any of you. I came here looking for help, but so far, I'm getting nowhere.

I think I'll just call T-Mobile today and discuss this. To those who've done so, thanks for your input.
