If you're truly inundated with spam calls on a daily basis, it may be a good idea to download an app that can filter your incoming calls. 

Spam-blocking apps work by checking whether each number you receive is a known spammer or not, blocking it from getting through to you if it is. However, given the slippery nature of spammers, some calls may still make it through the net.

Still, it may be worth checking out a spam-blocking app to see if it works for you, since most of them are free. 

If you're in the US, the top three cell providers have their very own call-blocking apps: AT&T Call Protect (opens in new tab), T-Mobile Scam Shield (opens in new tab), and Verizon Call Filter (opens in new tab).

And if you're elsewhere, it's worth checking if your provider has its own app. Failing that, there are countless third-party alternatives, such as Robo Shield (opens in new tab) and Truecaller (opens in new tab).
