#662# Scam Block for RoboCalls - How it Works

How It Works and Carrier Limits

• Carrier Restriction: This shortcut code only works on the T-Mobile and Metro by T-Mobile networks. Other major carriers like AT&T and Verizon do not support this vertical service code and require their own security apps.
• Network-Level Action: Instead of just labeling a number as "Scam Likely" on your caller ID display, turning on Scam Block intercepts the flagged call at the carrier core and terminates it instantly.
• Not 100% Effective: While it drastically reduces automated and high-risk robocalls, it cannot block spoofed numbers that use fresh, unflagged 10-digit combinations or general text message spam.

Additional Management Tips

• Use the App: You can further manage these settings or review blocked logs by downloading the free T-Life app (for T-Mobile) or the Scam Shield app (for Metro).
• Report Spam Texts: Carrier call block codes do not filter SMS or MMS spam. Forward unwanted text messages directly to 7726 (spells SPAM) to help the carrier security teams fingerprint and block future messages.
