Do you need to apply for a secondary number for Huawei watch3pro calls?

Huawei watch3pro calls don't need an auxiliary number. Because watch3 watches support dual-terminal services of eSim- 1, you can use watch3 as a secondary card under your personal mobile phone number (primary number) only by adding watch3 to the eSim accessory equipment, and you can directly use Watch 3 to make calls and surf the Internet without carrying your mobile phone. In addition to independent calls, you can also listen to songs independently, and you can listen to songs directly with the Huawei music program on your watch.

Huawei watch3 features

The biggest highlight of Huawei Watch3 is that it runs the HarmonyOS system, and it can be used independently, no longer relying on mobile phones. It is a real "model" device for the Internet of Everything. As long as Huawei WATCH3 is held in your hand, it can be used as a car key, a door key, an air conditioner, a TV and all the smart devices in your home. As long as your device is blessed by Huawei HarmonyOS system, this watch can completely replace the mobile phone.
