SMS can't remind you in time.

According to the information you provided, if you mean that the traffic reminder message is not timely, there will be a SMS reminder when your package runs out of traffic. 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. SMS reminder is only an auxiliary function. It is suggested that you can send CXLL to 100 10 to inquire about traffic usage.

It is recommended that you troubleshoot through the above situation.

If this is not the case, it is recommended to contact the Unicom customer service to which the number belongs.
