Huawei Watch Ultimate 2 has a new update: Upgraded eSIM and sensors.

Huawei has begun rolling out a new software update, HarmonyOS 6.0.0.156, for its high-end smartwatch, the Watch Ultimate 2. This update brings two key improvements, focusing on enhancing standalone connectivity and accuracy in health tracking.

Enhanced functionality with eSIM

One of the most notable upgrades in HarmonyOS version 6.0.0.156 is the addition of new options for calls and SMS messages when users have activated eSIM on the watch. This improvement allows users to make and receive calls, as well as send and receive messages more seamlessly directly from the Watch Ultimate 2 without needing to connect to a smartphone.

This feature reinforces the role of smartwatches as standalone devices, offering maximum convenience to users in situations such as exercising, traveling, or simply wanting to temporarily leave their phones behind.

Enhance accuracy for professional users.

The new update also opens up the possibility of connecting the Watch Ultimate 2 to external sensors, typically dedicated heart rate monitors such as chest straps. This is a significant step forward for athletes and those who train seriously.

Connecting to external sensors allows for more accurate heart rate data collection compared to integrated wrist-mounted optical sensors, especially during high-intensity workouts or those involving complex movements. This provides users with more in-depth and reliable analyses of their training performance and fitness status.
