Why do mobile phone numbers always receive pre-stored text messages?

The reason why mobile phone numbers always receive pre-stored text messages:

1, if you don't operate it yourself, then it is possible that the other party's mobile phone number is very similar to yours, with a difference of 1 digit. When entering, the hand shakes and the input is wrong, which causes the verification code to be sent to your mobile phone number. This situation can be ignored.

2. If you receive a large number of short messages in a short time, it may be that the other party is attacking your mobile phone with a software. This software is a tool called SMS Bomb. After entering the corresponding number, you can send short messages in batches without interruption. In this case, you can choose to call the police, because after all, it has caused trouble to your daily life. You can also try to install some security software and maybe intercept some spam messages.

3. If the received SMS verification code is a familiar APP or website, you can log in and have a look. Maybe someone else tried to log in to your account, because too many mistakes triggered security verification. Suggest that I change my previous password after logging in.
