What are the precautions for using an eSIM card?

When activated, the eSIM card is in the Auto mode by default. In the "auto mode," if the watch and the mobile phone are connected properly, the system will automatically turn on or off the eSIM card function according to the current network usage. When the watch and the mobile phone are disconnected, the eSIM card function will automatically remain on, thus helping to save power and traffic. It is recommended to keep the Auto mode selected.
