Do satellite phones work exactly the same way as cell phones?

Not quite. The major difference is the antenna on your satellite phone must have a clear line of sight to the sky. Satellite phones work best when used outside without obstructions like tall buildings, mountains or trees. For optimal results, take a 360 degree view of your surroundings, if there is anything between you and the sky, move locations. Signal strength may weaken in towns and cities or inside buildings.
