Would be also interesting to see how this solution compares to the Chinese BeiDou based network that Huawei is using. Is this similar a standard? Meaning that iPhone at one point would support BeiDou or is it completely different?
The first phone maker to add satellite texting to its devices is... Huawei
Huawei has announced the Mate 50 series, a day ahead of Apple’s September event and with a feature that the iPhone 14 is expected to offer: the ability to send texts via satellite communication. The Mate 50 and Mate 50 Pro will be able to send short texts and utilize navigation thanks to China’s global BeiDou satellite network, allowing for communication in areas without cellular signal.
It seems Apple uses the GlobalStar LEO satllites for these communication.[0]
Huawei is using BeiDou[1], which is the navigation satellite system. BeiDou is something just like GPS, but has the capability to send short text message. Huawei is using that function for SOS meesage.
Basically you can expect wherever you can receive navigation signals, you can send your SOS message.
