Every time your phone beeps to signal that a new SMS has arrived, you tend to believe that it’s a message from family, friend or colleague –but what great disappointment it cause when you open the message only to see an “unbelievable offer!” You’ve wished so many times if you could block all these unwanted phone calls! Thankfully, nowadays there are ways to block calls on mobile phones using apps like Truecaller. The Telecom Regulatory Authority of India (TRAI) came to customers’ rescue when this nonsense method of marketing grew beyond a limit. TRAI started a DO NOT DISTURB aka DND registry and mandated that if a consumer’s phone number is listed in this database –it would be illegal to make marketing calls or send such messages to that number. SEE ALSO: How to Register in National DND Registry Once you get registered in DND, you’re not supposed to receive any annoying marketing calls. But in reality, you still do get such calls/sms. Although the number and frequency may get reduced. So, it’s beneficial to some extent. Also, if you register in DND database, you can take legal action against such callers. So, after registering, how to check if your number is actually there in the database? TRAI has setup a website for this purpose. Go to Telecom Commercial Communications Customer Preference Portal and enter the phone number you want to check for. The site immediately informs you of the DND status of the phone number. If your mobile phone number turns out to not be listed in this registry –it is highly recommended that you immediately take steps to register it.
