How to stop spam call and spam messsages in India by sending sms to 1909

 In India, you can stop spam calls and messages by using the National Do Not Disturb (NDND) service. You can activate this by sending an SMS to 1909, which is a toll-free number managed by the Telecom Regulatory Authority of India (TRAI).

Steps to Stop Spam Calls and Messages via 1909

1. Fully Block All Promotional Calls and Messages (Full DND)

• To completely block all types of promotional calls and SMS:
  • Send START 0 to 1909 via SMS.
  • You will receive a confirmation message, and it may take up to 7 days for the service to be fully activated.

2. Partially Block Specific Categories of Promotional Messages (Partial DND)

• If you want to block spam calls and messages only from specific categories (e.g., real estate, education, health), you can selectively block them. Here's how:

  • Send START <Preference Number> to 1909, where you can replace <Preference Number> with any of the following categories:
    1. START 1 – Banking, Insurance, Financial products, Credit cards.
    2. START 2 – Real Estate.
    3. START 3 – Education.
    4. START 4 – Health.
    5. START 5 – Consumer goods and automobiles.
    6. START 6 – Communication, Broadcasting, Entertainment, IT.
    7. START 7 – Tourism and Leisure.

• For example, to block real estate promotional calls/messages, send START 2 to 1909.

• You will receive a confirmation message once your request is processed.

3. Deactivate DND Preferences

• If you want to stop blocking promotional messages and calls, you can deactivate the DND service:
  • Send STOP to 1909.
  • You will receive a confirmation message that the DND service has been deactivated.

4. Register via Call

• You can also register for DND by calling 1909 and following the Interactive Voice Response (IVR) system instructions to set your preferences.

5. Report Spam Calls or Messages (for Registered DND Users)

If you are still receiving spam calls or messages after activating DND:

• Send an SMS: Forward the spam message to 1909 in the following format:

  • For unwanted calls: Send COMP TEL NO XXXXXXXXXX to 1909 (replace "XXXXXXXXXX" with the number from which you received the spam call).
  • For unwanted messages: Forward the spam message to 1909 and follow the instructions to report it.

• You can also call 1909 to register a complaint about unwanted promotional messages or calls.

Important Notes:

• The DND activation may take up to 7 days to fully block promotional calls and SMS.
• Transactional SMS (such as OTPs from banks, transaction alerts, etc.) are not blocked by DND.
• The service is free of charge.

By sending the appropriate SMS to 1909, you can effectively stop most spam calls and messages in India
