T-Mobile and Sprint Can Now Verify <br />Real Callers to Protect Against Spam Both companies are using a verification system <br />called SHAKEN/STIR to confirm that calls from <br />each other's networks aren't robocalls. The system provides users with a <br />symbol or alert when an incoming call <br />is being made by an actual person. However, for the system to be fully functional, every <br />phone service provider would need to set it up and <br />integrate it with all other phone service providers. Additionally, not all phones <br />support the verification system. According to The Verge, T-Mobile and Sprint may also <br />end up merging, making the system less useful. President Donald Trump recently <br />signed a law requiring service <br />providers to start putting verification <br />protocols into effect within the next year. This may help speed up the process of getting all <br />phone service providers to utilize the same verification <br />system, though a plan has not yet been confirmed.
