Apple’s satellite connectivity, initially introduced for emergency assistance on iPhones, is making its way to the Apple Watch Ultra. According to Bloomberg, the next generation Apple Watch Ultra, expected in 2025, will enable users to send text messages via Globalstar Inc.’s satellite network when cellular or Wi-Fi connections are unavailable. This functionality will operate independently of the iPhone, making the Apple Watch Ultra potentially the first mainstream smartwatch with standalone satellite connectivity.

This feature’s evolution began two years ago with emergency services contact, later expanding to roadside assistance. iOS 18 further broadened its capabilities, allowing text messaging over satellite networks. This advancement for the Apple Watch Ultra signifies a significant step towards off-the-grid communication, particularly beneficial for hikers and those venturing into areas with limited connectivity.
In addition to satellite connectivity, the next Apple Watch Ultra is rumored to receive a 5G upgrade, specifically the 5G RedCap (Reduced Capability) version. This technology, developed by Ericsson, offers improved data rates, lower latency, and better energy efficiency compared to 4G LTE. While not as fast as standard 5G, 5G RedCap targets 150 Mbps downlink and 50 Mbps uplink, aligning with the requirements of wearables like smartwatches. Ericsson highlights RedCap’s suitability for devices like smartwatches, medical devices, and low-end AR/VR glasses.

These upgrades coincide with Apple’s reported transition from Intel modems to MediaTek for cellular connectivity in its smartwatches. This aligns with Apple’s broader strategy of developing in-house technology, as evidenced by the planned inclusion of their own modem in devices like the upcoming iPhone SE refresh.
While Apple continues to innovate, some highly anticipated health features remain under development. Blood pressure monitoring is reportedly still in progress, with no confirmed release date. Similarly, noninvasive blood glucose monitoring, a feature already available in competing devices like Samsung’s smartwatches, is also being explored by Apple, but its arrival remains uncertain. In the meantime, Apple has focused on other health-related features, such as hearing aid assistance introduced for AirPods earlier this year.
The next Apple Watch Ultra’s anticipated satellite texting and 5G capabilities promise significant advancements in connectivity and functionality. While the timeline for advanced health features remains unclear, these updates represent Apple’s ongoing commitment to pushing the boundaries of wearable technology.
