What’s the difference between a cell phone and a satellite phone?

The main differences between sat phones and cell phones are:

Coverage

While cell phones use land-based stations for communications, satellite phones usually communicate directly with a satellite. As a result of this the coverage area of these two types of services varies significantly. While GSM networks cover most highly populated areas, many rural territories still lack such coverage. Satellite phone networks on the contrary can cover very large areas and in some cases the entire globe.

Size

Most satellite phones are still slightly larger and heavier than modern cell phones. A few satellite phone vendors have released though satellite smartphones which resemble quite closely standard GSM cell phones.

Price

In general satellite phones are still more expensive than most GSM phones. A new satellite phone will often cost in excess of $1000.

Functionality

Most satellite phones are designed to offer basic call, message and data transfer functionality, although common smart-phone features are available on some new satellite phones.
