Locate My Device is an application miming Google's Find My Device – through SMS. It can help you to locate a lost smartphone.
How it works? Simply send an SMS to the device you want to locate in order to retrieve information about it. The SMS must consist of the configured activation command, a password and an instruction – e.g. "locate" if you want the coordinates, "battery" for some battery details, "ring" to make it ring – or "lock" to lock it down.
