Why didn't you receive any reminder message before the traffic usage exceeded, and then you received the message after it exceeded?

Hello! When the mobile phone accesses the Internet and the package traffic runs out, the operator's billing system will send a SMS reminder, and the data of SMS reminder is for reference only. The specific usage is subject to the telephone bill. There are two main situations about the delay in receiving SMS reminders and the inability to receive SMS reminders: \x0d\ 1. Because of the delay in the settlement of traffic bills, it takes a certain process to trigger SMS reminders after bills are put into storage, and a large amount of traffic is used in a short time. It is suggested that you can know the daily traffic usage in real time through third-party traffic monitoring software or through China Unicom APP and Webroom. \x0d\2。 If third-party mobile assistant software is installed on your mobile phone, such software may block the SMS port of 100 10, or the user terminal may not receive the consumption reminder message at this time. I suggest you check whether the third-party mobile assistant software is blocked first.
