The mobile phone receives the mobile phone verification code information in the middle of the night.

Someone else filled in the wrong mobile phone number or leaked information.

It is possible that someone accidentally entered the wrong phone number and sent it to your mobile phone, but it is unlikely to be in the middle of the night. It is very likely that personal mobile phone information was leaked and maliciously harassed.

Interception can be set. Nowadays, the interception function of most mobile phones is very powerful. You can set up automatic SMS interception, for example, strange number interception, keyword interception, etc. Be careful when setting, because it is possible that your normal text messages will be intercepted.
