Huawei mobile phone travel reminder card is not displayed.

This is because you turned off this reminder function, so there is no reminder.

Select Smart Assistant Today on the homepage of Smart Screen. In the negative screen interface, click the avatar in the upper right corner. Enter my interface, select Huawei account, and log in to your Huawei account according to the interface prompts.
