Why does Samsung 869 mobile phone automatically turn on traffic every time it sends a text message?

According to your description, you can refer to:

1. Try to restart the machine.

2. Test after uninstalling the recently installed third-party software, and preliminarily rule out whether it is caused by the third-party software.

3. After running the browser, email and other programs, it is recommended to press the "Back" button to exit. If you press the "Home" button, the application will still run in the background, instead of actually closing it (or you can enter the task manager to end the program running in the background).

4. You can check what traffic is being used through the business hall corresponding to the SIM card.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the problem still exists, I suggest you take the three-guarantee certificate and send your mobile phone to the nearest Samsung service center for inspection and maintenance. Please visit the specific service center address:
