How to block spam calls?

Are you sick and tired of all the spam calls you get? Spam calls can get irritating and disturb users and often make them miss on important calls. But the Telecom Regulatory Authority of India (TRAI) allows users to block all spam calls and messages from all sectors. Sometimes these spam calls are also fraudulent calls, which target receivers pretending to be from a bank or related other deceptive identity.


To get rid of these calls, people try to block contacts. However, blocking every single spam number is not possible. But there is a way through which you can block and report spam calls in bulk or stop receiving spam calls and messages. There are several third-party apps—including Truecaller, RoboKiller, and Call Control—also work to block telemarketing calls. Let's take a look at all the various methods through which you can stop the spam calls.
