Yes, it is possible to use the Huawei Watch Ultimate as a headset for hands-free communication. The watch features a built-in speaker and microphone, allowing users to take and make calls directly from the watch when connected to a phone via Bluetooth[7][10]. However, there are some limitations to consider:
1. Bluetooth Connection Required: The watch must be paired with a phone to enable call functionality. This means you cannot use the watch independently for calls without a connected phone[8][10].
2. No eSIM Support: Unlike some other Huawei models, the Watch Ultimate does not support eSIM, which means it cannot connect to cellular networks independently. This limits its use as a standalone communication device[7].
3. Bluetooth Headphones Limitation: While you can pair Bluetooth headphones with the watch for listening to playback or audio, they do not support voice calls when connected directly to the watch. For voice calls, the headphones must be paired with your phone instead[4].
4. Hands-Free Communication: The watch itself can be used for hands-free calls, which is convenient during activities like cycling or running when accessing your phone might be inconvenient[7][10].
In summary, the Huawei Watch Ultimate can be used as a headset for hands-free communication, but it requires a Bluetooth connection to a phone and does not support independent cellular connectivity.
