DND in telecom stands for Do Not Disturb.
This feature allows mobile phone users to opt out of receiving unsolicited commercial calls and messages.
When a user registers for DND, their phone number is added to a national registry, preventing telemarketers and other businesses from contacting them.
DND services are typically offered by telecommunications companies and are usually free of charge.
Here are some examples of how DND works:
- Blocking Calls: A user with DND activated will not receive calls from telemarketers or companies they haven't explicitly given permission to contact.
- Filtering Messages: DND can also filter out unwanted SMS messages, such as promotional offers or spam.
- Protecting Privacy: DND helps protect users from intrusive marketing practices and ensures they only receive calls and messages from legitimate sources.
