How do Huawei watch4 watches talk independently?

Huawei Watch4 watches support independent calls, but pay attention to the following points:

1, need to support the eSIM card: independent calls need the built-in eSIM card of the watch, and some versions of Huawei Watch4 support the eSIM card, so it is necessary to confirm whether the eSIM card is supported when purchasing.

2, need to pair with a mobile phone: first, you need to pair the watch with a mobile phone, and then connect to the mobile phone network through Bluetooth or Wi-Fi, and then you can make calls independently.

3. Need to support VoLTE:VoLTE is a high-definition voice call technology based on IP network. Mobile phones and watches that support VoLTE can make high-definition calls, while mobile phones and watches that do not support VoLTE can only make ordinary calls.

4. Need to set it on the watch: Before using the independent call, you need to set it on the watch, open the phone application on the watch, and then follow the prompts to set it.
