Hey sirgg8344, just heads up - “cloning a phone” usually means sketchy stuff that’s not legal or realistic for regular parents. For monitoring your teen, you actually don’t need anything that complicated.
Best route: if they’re under 18 and it’s your phone plan, grab an app like uMobix (since you’re here), mSpy, or Bark - these need one-time physical access to install, then you can see texts from your dashboard. Way safer and more reliable than “cloning.”
Also worth checking: do you have Family Sharing set up on iPhone or Family Link on Android? You might already be able to see some activity without installing anything extra.
