Is it possible to track cellphone number without installing apps?

My kid has been staying out way past curfew and I really need to know their whereabouts without causing a huge fight. I know some carriers offer basic location services, but I haven’t been able to figure out how to use them without touching their device. Can anyone point me to a service that just requires their number to show live location, or is that actually impossible?

You can’t just drop a number into a website and get live GPS—consumer tracking always needs either a carrier family plan or at least a one-time setup tap on the phone, and those “track-by-number-only” apps online are mostly selling you snake oil and malware. If you’re the account holder, log into your carrier’s family dashboard to see what they actually offer, but be prepared to borrow the kid’s phone for about five minutes to approve it. Honestly, installing Apple’s Find My, Google Family Link, or Life360 once is way less headache than trying to bypass how modern phones actually handle location sharing.

Honestly, tracking by phone number alone is basically a myth—any site claiming to do it is likely a scam. Carrier family services exist but still need device setup and often require opt-in, so your best real option is installing a monitoring app like mSpy, which gives you live GPS, geofencing alerts, and location history once installed. TL;DR: if you want simple and legit, carrier features (with setup), if you want deep reliable data, use mSpy—just know you’ll need brief access to their device once.
