T-Mobile says it has blocked one billion scam calls made to its customers : 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 and Metro subscribers automatically are protected with Scam ID, which will warn users about a particular incoming call on their screens. Scam Block, which prevents a scam call from ever reaching a user’s device, can be enabled by both T-Mobile and Metro customers by dialing #ONB# (#662#). The service can be disabled by dialing #OFB# (#632#).
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.
