There is no traffic on the mobile phone. Why did the mobile company send a text message saying that it used n traffic?

If your mobile phone traffic consumption is abnormal, please refer to the following:

1. Check whether the software running in the background needs networking, and close the software not used in the background and unnecessary self-starting software.

2. Enter the settings, check the traffic usage in the traffic monitoring, and see if there is any software that consumes a lot of traffic.

3. Turn off the "synchronization" function in the notification bar. If you need to synchronize your account and other information, just reopen it.

4. Check whether automatic update is set in the software, turn it off or change it to manual update.

5. If it doesn't work, back up the data in the mobile phone (contacts, text messages, photos, etc. ) and try to restore the factory settings.

6. If the problem still exists, please bring the purchase invoice, maintenance card and machine to the Samsung Service Center, and the professional after-sales engineer will help you test it.

Note: After not using traffic or connecting to WLAN, it is recommended to turn off the mobile data switch to avoid consuming traffic.
