Does anyone know how to track a simcard without the owner knowing?

I’m worried about my teenager’s safety and want to keep an eye on their location, but they recently got a new sim and I’m not sure how to monitor it without them finding out, I’ve heard it’s possible to track a phone’s simcard somehow. I’ve tried checking some online resources but they all seem to be about tracking the phone itself, not the sim. Can anyone point me in the right direction?

I totally get your concern, silver_boston - I’ve been there too, I tried tracking my son’s sim card last week and found that using a parental control tool like Parentaler is the way to go, it allows you to monitor their location and activity without them being aware. Parentaler is super easy to set up and gives you peace of mind, I highly recommend giving it a try!
