The Huawei Watch Ultimate is equipped with satellite SMS technology, allowing users to send messages via satellite when traditional cellular networks are unavailable. This feature is particularly useful in emergency situations where communication is crucial but cellular coverage is lacking. The watch supports two-way satellite SMS communication, enabling users to both send and receive messages over satellite networks.
In emergency situations, users can utilize the "Beidou Key" on the watch to quickly activate the Beidou satellite messaging function. This allows them to send help information rapidly, ensuring timely assistance in critical situations. The process involves starting the BeiDou satellite communication function, searching for satellites, and sending the message. The receiving device will display the sent information along with the location, providing a double reminder to ensure the message is received by the intended recipient.
While the Huawei Watch Ultimate's satellite SMS feature is designed for general use, including emergencies, it is not explicitly marketed as an emergency SOS feature like those found on some iPhones. However, its ability to send messages via satellite in areas without cellular coverage makes it a valuable tool for emergency communication.
Huawei's innovative approach to integrating satellite technology into wearables like the Watch Ultimate demonstrates a commitment to enhancing connectivity in remote or emergency situations. The watch's design includes miniaturized RF modules and a suspended antenna to facilitate stable signal transmission, even in challenging environments. Additionally, Huawei has developed a battery intelligent heating solution to address power issues in low-temperature conditions, ensuring reliable performance when needed most.
In summary, the Huawei Watch Ultimate's satellite SMS feature can indeed be used for emergency communication in areas with no cellular signal, providing a vital means of staying connected when traditional networks are unavailable.
