Currently, there is no detailed information available about specific subscription costs associated with using the satellite SMS feature on the Huawei Watch Ultimate. However, it is known that the watch supports two-way Beidou satellite SMS in China, activated by holding the Ultimate button for three seconds[1][8]. This feature allows users to send and receive messages in areas without cellular coverage, which can be particularly useful in emergency situations.
For other Huawei devices, such as the Mate 50 series, satellite communication initially offered 30 free SMS per month, with no additional costs mentioned at the time of launch[3]. However, it was noted that satellite communication services can be expensive to maintain, and costs might be incurred in the future, potentially around 1 yuan (approximately 0.4 USD) per message[3].
As the Huawei Watch Ultimate's satellite SMS feature is primarily marketed in China and not globally, specific pricing details for this feature are not widely available. It is also worth noting that the upcoming Huawei Watch Ultimate 2 is expected to support satellite SMS, but details on any associated costs have not been disclosed yet[2].
