Robocalls happen day and night, ringing your cellphone, your landlines and wasting your time.

Although many of us are on the national and state "Do Not Call Lists,"  tech experts say most spammers and scammers rarely pay attention to that list, according to WNEP.

The information below includes responses from some of the biggest phone providers: Verizon, Sprint,  AT&T, and Comcast.

While most of the tools offered by these providers below can help stop or limit robocalls for free, some programs with the different carriers come with a fee.

Always read the fine print and ask your carrier about any additional costs when subscribing to robocall stopping technology.


"Currently, it's not illegal to spoof another person's phone number, but we believe it should be and we support federal legislation that would go after the spammers that are making these calls," says Verizon Wireless Public Relations Manager (Northeast Market) David Weissmann.

Coming this March, Verizon told WNEP it's expanding its current call filter blocking system and rolling out free spam alerting and call blocking tool that customers can sign up for.  Learn more here.

Right now, Verizon Wireless offers Caller Name ID app, which deployed over a year ago. The latest update, currently available on Android and iOS smartphones, allows subscribers to automatically forward spam calls that correspond to their selected level of risk straight to voicemail.

In addition, Verizon is committed to deploying the STIR/SHAKEN authentication standard in our networks. This would verify to end users that the number displayed on the Caller ID is the number that originated the call.

Many times these calls originate over the Internet and do not touch the Verizon network.

"Sprint is fully committed to deploying and implementing SHAKEN/STIR, and we are working vendors to begin testing various aspects of these protocols," says Sprint's Media Relations Representative Lisa Belot

Essentially, this new technology would help customers know if the number on their caller ID is real. Every phone would have a kind of digital signature attached to it. This signature would let customers know that the call they are receiving is actually coming from the number shown on the caller ID.

Sprint also offers a robocall labeling and blocking service called Premium Caller ID. (FAQs available here). This application allows Sprint customers on both Android and iOS devices to subscribe to an optional, paid service that empowers them to receive information about the type of caller that is attempting to reach them and to set up preferences to block spoofed calls and other robocalls.


In a statement, AT&T Media Relations says: "We have blocked more than 4 billion unwanted robocalls using an analytics system. It looks for patterns that may indicate an unwanted robocaller. AT&T offers several solutions for customers, including AT&T Mobile Security and AT&T Call Protect, free services that automatically block fraud calls, provide screen alerts for suspected spam calls and help protect smartphones from potential threats"
