A spam call is an unsolicited call where the intention is often to trick or scam the recipient. Spam calls are unwanted calls made to a large number of people from an unknown source. They often try to trick you to get money or information out of you. Spam calls can be identified and labeled with a spam risk label. The terms "spam call" and "robocall" are sometimes used interchangeably, but they can mean slightly different things. Robocalls are pre-recorded messages that are delivered with the same goal of making a sale.
To avoid spam calls, it is recommended not to answer them. If you answer the call, your number is considered good by the scammers, even if you dont necessarily fall for the scam. They will try again because they know someone on the other side is a potential victim of fraud. The less you answer, the fewer robocalls you will receive. If you suspect a phone number is spam but it is not labeled as such, you can flag a phone number as spam directly with your telephone carrier or efficiently, with a mobile app like Hiya that helps block incoming spam calls.
