 So here's what I want you to do instead. Turn on your phone's spam filter. If you have an iPhone, go to settings and messages, and that's where you can switch on filter unknown. On Android, open your phone app. It's that three-dot icon. Dive into settings, and there you want to enable caller ID and spam. And don't forget that your carrier also has some tools available to you. Like, for example, T-Mobile, they have a free app called ScamShield.
