Robocalls and spam calls might soon be less of a problem for Verizon customers.The carrier will offer its spam and robocalling protection features to all customers for free, starting in March. The tools will be available to Verizon customers with compatible smartphones, including iPhone and Android devices. Verizon promised to share information on how to sign up as it gets closer to launch.

Currently priced at $3 per line per month, Verizon's Call Filter service displays an alert if an incoming call is likely a robocall, spam, or fraudulent. You can also set up a filter to automatically send these calls to voicemail.

Rival carriers T-Mobile and AT&T already offer similar features for free.
