Scam ID is the one T-Mobile customers will probably become most familiar with, as it alerts customers to suspicious incoming calls before they pick up the phone. When a user receives a call flagged by Scam ID, it will be identified as “Scam Likely” in place of the caller ID.
T-Mobile says new customers of its One plan can expect to receive the feature on April 5, while existing post-paid customers can enable it for themselves on the same day by dialing #664#. Otherwise, T-Mobile will eventually enable Scam ID for all users.
Still, the carrier would ideally like to prevent scams from getting to you in the first place, which is what Scam Block is for. Scam Block works discreetly within the network, preventing those calls from ever reaching you. Unlike Scam ID, Scam Block has to be manually activated, and customers can do just that by dialing #662#. To turn it off, the number is #632#.
T-Mobile says with these features, every incoming call to the network is checked in mere milliseconds against a global list of malicious numbers. “Behavioral heuristics and intelligent scam-pattern detection” are active behind the scenes to keep that database forever current as new frauds pop up.
Last July, Google added a feature to the Phone app for Nexus and Android One devices that worked similarly to Spam ID, flagging certain incoming calls with a “suspected spam caller” alert. The update also allowed users to report spam calls that had been received and block those numbers on the spot.
