The mobile phone does not display the text message after receiving it, only the ringtone of the text message, and there is no new information in the inbox! Then the expenses will be deducted.

It seems that you've got a malicious plug-in for charging, and it's definitely not poisoned, because the S6v3 mobile phone has no virus. If someone recommends you to install Netqin antivirus, don't install it, otherwise your phone bill will be deducted faster. The fastest way to solve this problem is the (soft) grid machine. After you back up the card holder information (you can use PC suite, Nokia official website has it), enter * # 737 # in the standby interface, and then enter the lock code. Of course, it is best to format the memory card, and back up the things that are more important to you in the card before the format.

In addition, if you know which charging plug-in is up to something, you can find it in the program management and delete it.

If you think there may be something wrong with your number, you can send it to to 186 (mobile) or 11 (Unicom) to check what services you have subscribed to, and you can cancel it.

Finally, I wish you success ~
