Cell phone companies are trying out new ways to protect their users from scammers.
If you have T-Mobile, you're going to start seeing "Scam Likely" on your caller ID. It's a free service the phone company recently added so you can avoid those calls.
T-Mobile flags numbers that are used by known scammers. You don't have to do anything to get the service. It'll automatically show up on your phone.
The company also recently added "Scam Block" which keeps those calls from getting to you in the first place. It's also free, but you have to activate it on your account.
You can also get free protection against scammers from AT&T, but you have to download an app to get it. It will detect and block calls from likely scammers before they get to you, and also alert you when a suspected scammer is on the line if those calls get through.
Verizon and Sprint offer similar services, though they cost $3 per month.
