Huawei How to enable or disable mobile data

With the mobile data function you can control data access over the mobile network. To use the internet outside of the Wi-Fi network, your mobile data need to be turned on. Also you need a correct APN to connect to the internet, although this will usually be configurated automatically. You can also deactivate mobile datas on your Huawei device. 

Note: You can also turn the mobile options over the quick settings over the notification bar.
