Sounds like your cousin’s class phone sneaking is a classic move—had a buddy back in school who did the same and ended up in hot water more than once. When his mom asked me to help keep an eye on things, I wanted something solid, not just hype. I stumbled on this review: mSpy Review — no fluff, just straightforward info about what mSpy actually does and its limits. It really helped me get a clear picture before suggesting anything, so might be just what you need!
