Hello, friend!
You need to provide a complete device model. The following uses the E5576-320 as an example to describe how to access the device management page.
Using app: You may scan the QR code below to download HUAWEI SmartHome App to manage your Mobile WiFi, for example, changing your Wi-Fi name or password, or checking data usage.

If you cannot add the device to the app, please check if you are using the latest version.
Using browser: Enter 192.168.8.1 into the browser on your mobile phone or computer to go to your Mobile WiFi's web-based management page. The default login password is admin.
If you cannot visit the web-based management page, check whether your mobile phone or computer is connected to your Mobile WiFi.
We suggest that you modify the default Wi-Fi name and password, and the default login password to ensure that your data is secure.
Thanks!
