After nearly two years of hard work, China Telecom has released numbers to the commercial market for the first time, marking my country's entry into the mobile phone era of satellite mobile communications. It has filled the gap in domestic independent mobile communications systems and broken the status quo of relying on foreign satellite mobile communications services. It is an important milestone. The Tiantong-1 ground business is operated by China Telecom Co., Ltd. and will form a mobile communication network together with the ground mobile communication system. The Satellite Communications Branch of China Telecom Co., Ltd. and Tianhai World Satellite Communications Company are also intensively promoting the launch of the first domestic full-network + satellite mobile phone. This mobile phone with mobile satellite communication function is small and easy to carry. You can use it to communicate with family and friends in real time and without barriers even to the ends of the world, completely breaking the monopoly of satellite phones by foreign countries. The first batch of Tiantong satellite phone cards, Tiantong No. 1 satellite mobile communication system, covers the entire territory of China, territorial waters, and the first island chain; areas surrounding China, the Western Pacific and the Indian Ocean. Looking back at Wenchuan in 2008, after the magnitude 8 earthquake, the ground communication network in the earthquake area was completely paralyzed. At that time, China did not have its own mobile communication satellite system, so it could only purchase foreign satellite phones and rent foreign mobile communication satellite systems for earthquake relief.

This satellite phone integrates China's independently developed Tiantong-1 mobile satellite communication system chip, which is 100% Chinese. It can be used as an ordinary smartphone in urban public network environments. It can turn on satellite communication mode in areas where traditional ground mobile communication networks are not covered or are unstable. It is not affected by the ground environment. It can communicate with the outside world no matter where it is, making not in the service area a thing of the past. It refuses to be disconnected and no longer loses contact!
