China Unicom's short message delay caused my traffic to exceed the deduction fee. Is Unicom responsible?

Hello! When the mobile phone accesses the Internet and the package traffic runs out, the billing system will send a short message reminder, and the data of the short message 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:

Case 1 Due to the delay in the settlement of the traffic bill, it takes a certain process to trigger the SMS reminder after the bill is 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.

Case 2: If a third-party mobile assistant software is installed on your mobile phone, this kind of software may put the 100 10 short message port on the blocked list. At this time, it is also possible that the user terminal cannot receive the consumption reminder short message. I suggest you check whether the third-party mobile assistant software is blocked first.
