Xiaomi wantonly uses the traffic card to spam messages.

The reason why Xiaomi's mobile phone keeps checking the balance of the package and sending text messages may be because the automatic error correction function has not been turned off. You can turn off AutoCorrect in the network assistant, so you can't receive text messages. The specific operation steps are as follows:

1. Go to Desktop-Security Center-Network Assistant-Menu-Settings-Correction Automatic correction in traffic data has been turned off.

2. Check whether some applications in the mobile phone have enabled automatic traffic checking. You can find these applications and close them.

I hope the above information can help you solve the problem. Please feel free to let me know if you have any other questions.
