What's wrong with private numbers not showing numbers?

This situation is because the other party has turned on the hidden number function, network phone or virtual number, phone interception or filtering.

There may be several reasons why private numbers don't display numbers:

1. The other party has turned on the function of hiding the number: some mobile phones or communication software provide the option of hiding the number, so that the number will not be displayed when calling or texting.

2. VoIP or virtual number: When using VoIP or virtual number service, incoming calls may display some special numbers or codes instead of real numbers.

3. Phone interception or filtering: The interception function of the mobile phone may mark some numbers as harassing calls or spam messages, so that the numbers are not displayed.
