I used Unicom's 3g mobile phone card, and the traffic was overloaded, so I didn't receive the prompt message. I know I can't surf the Internet. I checked the phone bill before I received the short message of arrears and called customer service. 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 problems about the delay in receiving SMS and the inability to receive SMS reminders:

1. Due to the delay in settlement of traffic bills, it takes a certain process to trigger SMS reminders after bills are put into storage. However, a lot of traffic (such as software download, online video watching, online video chat, etc. ) The use time is short, and the package traffic is not triggered in time after use, which will cause this problem. It is suggested that you can know the daily traffic usage in real time through the third-party traffic monitoring software or through the mobile phone hall and network hall.

2. If a third-party mobile assistant software is installed on your mobile phone, such software may include the 100 10 short message port in the blocked list, and it is also possible that the user terminal cannot receive the consumption reminder short message at this time. I suggest you first check whether a third-party mobile assistant software is set to block.
