I lost Samsung Mobileg Phone grand 2

You can contact the service provider (and you must in order to avoid illegal charges) and get the phone de-activated. They may (very uncertain) be able to help you get your phone back.

There are some programs that will transmit a signal from the phone for remote tracking and recovery, but these programs must be installed and activated prior to the phone being lost.
