Not being in the service area becomes history, and my Chinese satellite is amazing!

This year is the tenth anniversary of the Wenchuan earthquake. The magnitude 8 earthquake that year struck abruptly, causing the ground communication network in the earthquake area to be completely paralyzed. Since China did not have its own mobile communication satellite system at that time, a lot of precious rescue time was delayed. After the Wenchuan earthquake, in order to solve this problem. Chinese aerospace scientists immediately carried out in-depth research, determined to fill the country's gap in the field of satellite mobile communications. As a result, there was Tiantong-1 01, a satellite communications that has no blind zone coverage throughout China and its territorial waters. Moreover, Tiantong No. 1 officially announced that the signal can be used as an ordinary smart phone signal, operated by China Telecom, and has been opened to the domestic market. That is to say: whether you are surviving in the desert forest or in the wilderness, the situation of no mobile phone service will never happen again! In the future, Tiantong Satellite will also play a role in marine transportation, ocean fishing, air passenger transportation and other fields. And in the event of natural disasters such as earthquakes, floods, frost, etc., barrier-free communication and location determination can be achieved. This kind of high-speed Internet service without dead ends is really exciting. However, while I am proud of my country, I also have a hint of worries. Since I can play with mobile phones on the plane, the party on vacation has lost a powerful excuse not to reply to WeChat. Now it’s a history that even the mobile phone is not in the service area. How can I explain why I don’t answer the phone calls of my boss and wife?
