The main market of satellite phones, and the introduction of classic models recommended
The first thing to explain is that the 99% network coverage promoted by the three major operators refers to "population coverage". The "land coverage" is only about 30%, which means that there are no mobile phone signals in the deep mountains, deserts, and Gobi deserted areas. And territorial coverage does not include territorial waters and exclusive economic zones, there must be no mobile phone signals at sea.
As long as there is no cell phone signal, a satellite phone is necessary:
Friends and self-driving tour: Self-driving tours, especially to Tibet, Xinjiang, western Sichuan, and Inner Mongolia, what if the car is broken in an unmanned area? A satellite phone can call for rescue at any time.
What should I do if my donkey travels on foot, and the weather is bad, injured, and lost? When the outside world found that they lost contact, they went to search, and the ending was nine dead. With satellite phones, the location and status can be notified. Rescue personnel can quickly find the trapped people and quickly implement rescue. The rescue cost is greatly reduced and the rescue success rate is very high.
The Beidou short message terminal can also achieve similar functions, but each tens of characters of text messages cannot be quickly communicated, such as the damage of the trapped person or the vehicle, what external support is needed, and relevant information about self-rescue. Complex content can be quickly resolved through two-way communication via satellite phones.
