The App helps you:

1. Set your DND preferences. All telemarketers are required to obey your preferences within 7 days of their being set.
2. Lodge a UCC complaint with your service provider. The Complaint sms sent against spam sms/call will be sent to 1909 in the format prescribed by TRAI and will not be charged. The Regulations require action to be taken against offending telemarketer within 7 days, which could lead to fines and/or disconnection of line.
