If we activate a mobile hotspot on the Huawei smartphone, we can set a data limit to keep an overview of our own data volume. Once the set data volume is reached, the device automatically turns off the mobile hotspot. If it is enabled again afterwards, the consumption is automatically reset to start counting again.
