How to change the card after Huawei Children's Watch 3 is restored to factory settings?

After Huawei Children's Watch 3 is restored to factory settings, if you want to replace the SIM card, you need to do the following:

1. Find the setting options on the watch and enter the setting menu.

2. Locate the "Device Management" or "Network Settings" option and click Enter.

3. In the device management or network settings, find the option of "SIM card management" or "SIM card settings".

4. In SIM card management or SIM card settings, select the option of "Replace SIM card" or "Switch SIM card".

5. You will be prompted to insert a new SIM card. At this point, you can insert a new SIM card into the SIM card slot of your watch.

6. Wait a moment, and the watch will automatically detect the new SIM card and configure it.

7. After the configuration is completed, the watch will be reconnected to the network corresponding to the new SIM card, and you can use the communication function of the watch normally.

Reason: After the factory settings are restored, Huawei Children's Watch 3 will clear all personal settings and data, including the previously configured SIM card information. Therefore, when the SIM card needs to be replaced, the new SIM card needs to be reconfigured by manual operation, so that the watch can be connected to the new network operator.

Extended content: When replacing the SIM card, it is necessary to ensure that the new SIM card matches the network standard supported by the watch. In addition, if you use other functions in the watch, such as location service and parental control, you may need to reconfigure these functions to adapt to the new SIM card. In addition, if the watch cannot be normally connected to the new SIM card after the factory settings are restored, you may need to contact Huawei customer service or operator for further help and support.
