It's 2019 and there’s still no solution to end robocalls. Now, cell phone companies are taking their own steps to block these annoying calls.
T-Mobile, AT&T and Sprint have either already started, or will soon begin, implementing the STIR/SHAKEN standards, which are protocols that verify if a call is real or if it comes from a computer.
T-Mobile also has additional measures to protect you from these calls. The company built its own database of fake numbers. Anytime you get a call from these numbers, your caller ID will label the call as "spam likely."
AT&T also hooks up its customers with a free app called Call Protect. It's similar to No-Mo-Robo, which blocks robocalls. AT&T identifies robocalls by looking for patterns in the calls. A paid version is also available.
Sprint offers premium caller ID at an additional price. Every call that comes through your phone will be identified.
Now, Verizon doesn't use STIR/SHAKEN on its network. However, the company is about to offer a free app that blocks robocalls. It'll also alert customers of potential spam calls and will provide a caller ID on all calls.
The new app rolls out in March.
