T-Mobile says it has blocked one billion scam calls made to its customers
2

Back in March, 2017, T-Mobile introduced a new feature called "Scam ID," designed to warn subscribers that an incoming call is likely to be a scam (the screen will say "Scam Likely"). In addition, members could opt in to "Scam Block," which blocks calls from certain numbers from reaching their phones, although that would be at the risk of blocking legitimate calls.
T-Mobile also announced today that it will agree to follow the FCC's new call authorization standards called SHAKEN (Secure Handling of Asserted information using toKENs) and STIR (Secure Telephony Identity Revisited). These new standards will allow carriers to verify that the person making a call is the actual person using the phone number listed on an incoming call. This way the wireless provider can prevent subscribers from receiving calls from stolen phone numbers.
The Google Pixel 3 and Pixel 3 XL both have a feature called Call Screen that alerts a user to an incoming call from an unknown number, and asks if he/she want the call screened. If the user replies in the affirmative, Google Assistant screens the call, allowing the user to read what is going on through a real-time transcript. The user can join the call at any time. This feature will soon be made available to the Pixel and Pixel 2 models.
