Can U Track Some One Location By Their Cell Phone?

There's two ways it can be done.

First is via GPS - either built into the device or as an add-on.  Add-ons are usually a bad idea as they have to be internally added, which involves micro-screwdrivers and a magnifying apparatus.  That also voids the warranty as it's an unauthorized modification - unless you have a location nearby with repair authorized certification from that manufacturer.

Another way is to subscribe to what's called "Mapping" by the service provider.  The cost of this can be anywhere from $4.99 per month on up to $19.99.

Hope this helps!
