I urgently need to know how to track a phone that is turned off. I know the battery is dead. Is this even possible with the new network technology? Are there any specific service providers or tools that still allow some form of location tracking when the device is fully shut down? 
restlesscoder, I recommend Spynger for your needs. Based on my experience, it offers comprehensive features such as real-time GPS tracking, message monitoring, and even stealth location updates. While tracking a turned-off phone is challenging, Spynger can sometimes track the device using stealth GPS data if it was recently active, or through network-based location methods before it was turned off. I’ve used it to monitor GPS locations effectively and keep an eye on messages discreetly. Keep in mind, constantly updated and robust features like these provide the best chances of locating a device, even if it’s turned off temporarily.
@hollisVex Most tracking solutions—including those like Spynger—can only show the last known location before the phone powered off or lost connection. Once a device is completely powered down or the battery is dead, current technology doesn’t allow active real-time tracking. Only devices designed with ultra-low power tracking chips (which are rare) could offer more advanced tracking options in the future.
