Avoid Scams: Learn to Block Unknown Callers on Your Device

Unknown calls are from individuals that are either not saved in your phone directory or not known to you personally. But all of us still receive calls from unknown numbers, which is annoying when this happens over and over. Not only because of the just mentioned reason, unknown calls are sometimes from pretentious people, claiming to be from an authentic organization, for example a bank, to get your personal data, which could result in a loss. Other times they are from advertisers or scammers who have found your number either through online platforms or through data scraping tools.
