Unicom esim configuration file download failed.

Don't use wifi to download, try to use mobile phone card to move data.

Some devices have eSIM and physical SIM cards. If you don't see the management esim profile, but you will see that this sim card is used in the mobile phone network settings screen at the top of the mobile phone network data, please select another sim card from the drop-down box and see if the link to manage the eSIM profile is displayed.

ESIM allows you to connect to the Internet through a mobile phone data connection. With eSIM, you don't need to get a SIM card from a mobile operator, and then you can quickly switch between the mobile operator and the data traffic package.
