There are two main ways to track a satellite phone. One way is by using an online service which requires you to log in and provide your personal information, like name and address. The second way is by using a GPS enabled app on your smartphone. The GPS tracking method uses the cellular network signals in order to locate the device. The process starts by sending a signal from the phone to the nearest cellular tower and then back to the satellite phone. This data is then processed by an algorithm in order to calculate its location.
