To customise DND settings:
DND registration takes up to 7 days to fully activate. Non-commercial spam (e.g., individual scam calls) may still occur. It is because the DND primarily targets registered telemarketers. If spam persists, report the number to Airtel by calling 1909.

You can also report spam calls to Airtel or TRAI for any action. This helps them take action against the spammer.
You can now report spam calls or messages directly through the Airtel Thanks App. Go to the “Help & Support” section.
Airtel investigates reported numbers and may block them if found to violate regulations. TRAI can impose penalties on registered telemarketers.
