Note:
The data traffic on the device side may be inconsistent with the carrier.
The traffic statistics function depends on the system time. Traffic statistics are not
available until the device time is synchronized to the network time.
In addition, if the device is often interrupted during use, it may cause inaccurate traffic
data.
2.3 Basic settings
