There are two main disadvantages of satellite communication.
The first is cost. Developing, launching and maintaining a satellite is extremely expensive. No further explanation of that is necessary.
The second is the time delay in responding.
Communications satellites are typically positioned so they rotate around the earth at the same rotation rate as the earth. This is called 'geosynchronous' positioning.
The geosynchronous orbit is far from earth, so the time it takes for the signal to reach the satellite and then bounce back to earth is about half a second.
The delays can be very annoying on voice calls, as people tend to talk over each other.
The delays are also problem with data exchange, as data response packets are also delayed which limits the effective bandwidth of the channel.
One way broadcasts, like TV and Radio signals are perfect for satellites as no response is required.

A Cheap GPS is a Bad Idea?
Many people try to save on navigation systems by purchasing a cheap GPS. While a cheap GPS system may provide basic routing, it's important to understand some of the limitations of a cheap GPS system. GPS navigation systems are designed to receive signals from specialized satellites in the sky. Since the signal from these satellites is very weak, a GPS receiver must be designed to effectively hold these signals. In many cases, a cheap GPS system will offer poor satellite reception. This may mean that a GPS won't work when there are obstructions in the sky. These obstructions can include tall buildings, trees, mountains, a vehicle roof and more. It's important to make sure that one buys a GPS navigation system that has good reception.
