China Mobile's mobile phone card sends out a lot of short messages from time to time inexplicably.

Your mobile phone must be poisoned! ! ! You don't have to ask that 360 scanning is not necessarily accurate. Many mobile phones, especially cottage phones, are embedded with background Trojans, which cannot be detected by anti-virus software. Send you customized text messages directly in the background. There are some viruses. I tried them myself. I automatically send you SMS and MMS in the background, but there is no record of you in the outbox. Later, I also brushed anti-virus software.

If you can't find out what's wrong with 360, it is recommended to upgrade the 360 virus database or replace the mobile phone antivirus software.

Of course, it depends on what mobile phone you use. If it is a fake, there is basically no solution, and people will pack Trojan horses in firmware.

If it is not a fake, the most direct suggestion is to go to the mobile phone store to help you brush a firmware. If you reinstall your mobile phone, there will be nothing.
