These calls can be from telemarketers, automated bots, or scammers. Blocking them helps you:
- Avoid spam interruptions

What Makes People Hide Their Numbers?
There are several reasons why people tend to hide their numbers or keep their numbers private on Telkom. In this section of the article, we will be taking a look at what makes people hide their numbers.
Well, on the top of the list is that as a Telkom mobile phone user, you would want to pass a piece of information across to another mobile phone user, however, you do not want your identity to be revealed so you would like to make it private to achieve your aim.
Another reason is that people like to keep themselves anonymous to tailgate others through phones. Tailgating simply means stalking people or following people very closely. People who are trying to tailgate others normally would want their identities to be private to achieve their intended aim because if their identities are revealed their activities will backfire and whatever they have planned would not materialize.
In addition to the points raised above, there are several individual reasons why people would like to hide their identities and numbers, and with that, it is individually based because your reason for hiding your number would be different from mine and mine too will be different from yours although, at a point, some of these reasons might be similar.
