Miui 13 always prompts SMS to verify traffic.

If you turn off automatic correction in the network assistant, you won't receive text messages. The specific steps are as follows:

Find the "security center" where Xiaomi's mobile phone is turned on, and you can see a "network assistant" icon inside. Click "Traffic Correction", select the mobile phone operator and home, and click SMS template update. After the update is completed, turn off the "AutoCorrect" switch and you won't receive the message.
