Received 1 serial digital short messages.

You need to provide your specific mobile phone model for analysis. Doubt two things.

1. Someone saved this number as the name of your colleague (if your mobile phone may be out of your control, such as being borrowed).

2. Don't rule out bugs in your mobile phone system. The possibility of mobile phone virus is almost zero. But you need to provide your mobile phone model.

As for the disappearance of SMS, it may be because the system crashed unexpectedly, and it may also be that your mobile phone has been tampered with (for example, a smart phone can pop up SMS regularly, and then delete the information while shutting down the system). But you must provide your mobile phone model.

Suggestion:

1. Refresh the phone after the phone data is backed up. Check the software.

2. Be sure to watch your mobile phone, and don't let others use it.

3. Go to the operator's business hall and bring up your short message list, which should contain sending and receiving mobile phone numbers.
