T-Mobile Scam Shield vs Truecaller

T-Mobile Scam Shield provides call, text, and web protections for customers on T-Mobile’s network. Incoming calls T-Mobile identifies as likely scams can be labeled Scam Likely, helping customers decide whether to answer or block them. Scam Block can automatically block those calls and can be disabled at any time. Included anti-spam protection covers SMS and MMS, while Safe Web Browsing helps block known malicious or dangerous sites on supported devices and experiences. Calling a number on the Scam Likely list triggers an audible warning through Callback Protection. Network protections work automatically without the app; customers can manage ScamShield in T-Life, turn on Scam Block by dialing #662#, or use My T-Mobile or the T-Mobile app. ScamShield is available for Android and iOS. The free plan is free at no extra cost for T-Mobile customers with qualifying service and a capable device. ScamShield Premium is $4 a month per line and adds categorized call types sent to voicemail, reverse number lookup, and automatic voicemail transcription by text.
