Why is my package traffic lost and there is no SMS notification, which leads to the deduction of the phone bill?

1, there will be a SMS reminder when the package traffic runs out. If there is a delay, it is not excluded to continue to use traffic data. At this time, you can't monitor the traffic you use in real time, so you need to disconnect the network and send the data back to the system for statistics.

2. SMS reminder is only an auxiliary function. It is suggested that you can send CXLL to 100 10 to check the traffic usage.
