Unlike standard GSM cell phones satellite phones have to be capable of communicating with satellites that are hundred, or in some networks even thousands of kilometers away. Because of this they need more powerful antennas and larger batteries.
Satellite phones are usually also designed to be more rugged than normal cell phones. All of these factors contribute to sat phones being both somewhat larger and heavier than most GSM phones. Users should also note though that many new satellite phones are relatively small and light, especially when compared to the previous generation of satellite phones.
You’ll find detailed reviews of satellite phone services and equipment on the Satellite Phone FAQ website. Read additional information on different satellite phone providers:
