Originally Answered: How do I make a call to a switched off phone? The only way is to call someone else who is nearby. If the phone is really off, there is no electricity, no energy for anything to work. Its memory however is still able to maintain its contents, and the internal clock is ticking.

Yes, both iOS and Android phones can be tracked without a data connection. There are various mapping apps that have the ability to track the location of your phone even without the Internet connection. When your phone has a data connection or is connected to WiFi, it uses Assisted GPS or A-GPS.

Often, if you’re calling someone’s phone and it rings only once then goes to voicemail or gives you a message saying something like “the person you have called is unavailable right now,” that’s a sign the phone is off or in an area with no service.

When you turn off your phone, it will stop communicating with nearby cell towers and can be traced only to the location it was in when it was powered down. According to a report from Washington Post, NSA is capable of tracking cell phones even when they are turned off.
