Why can't my Xiaomi mobile phone traffic be corrected?

Xiaomi's mobile phone traffic is always unable to be corrected because of correcting errors. The solution is as follows:

1. Find the setting icon that comes with MIUI system on Xiaomi desktop, then click Open to find other application management, and click in.

2. After entering other application management, find the network assistant (English: data usage) and click it.

3. On the page, click Clear Data.

4. After clearing the data, the notification bar will immediately receive a message from the network assistant (SIM card has no traffic package, do you want to set it? ), click enter or enter the security center to reset the flow.

5. After the setting is completed, you will get a page showing how much traffic is left and how much traffic has been used, and then you can see that the traffic has been automatically corrected. After the correction, you will be prompted whether the correction was successful or failed. At this point, the flow correction returns to normal.
