If the Internet traffic of my Unicom mobile phone is not enough, will there be a SMS reminder?

There are SMS reminders. Guangxi Unicom uses 90% of mobile phone traffic, and the system will send a text message to remind that the traffic is about to run out. After the traffic runs out, a text message will be sent to remind the traffic to run out. If there is a delay, it is not excluded to continue to use traffic data. At this time, it is impossible to monitor the used traffic in real time, so the data needs to be disconnected and sent 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.
