ATT ActiveArmor for iPhone

Overview: What ActiveArmor Does for Your Phone

AT&T ActiveArmor is a mobile security application for iPhone that provides a free baseline of protections and an optional paid tier for extra defenses. It focuses on blocking nuisance and fraudulent calls while offering tools to help keep your device and personal information safer.

Core protections and call controls

• Regular system health checks, passcode validation, and alerts if your information appears in a known data breach
• Options to direct incoming calls by category — accept, reject, or send straight to voicemail
• 24/7 automatic blocking of suspected fraud calls, plus spam call filtering
• A personal block list where you can add specific numbers you don’t want to hear from
• Notifications for nuisance calls so you know when problematic numbers try to reach you

Premium add‑on: Advanced Mobile Security

For a monthly fee of $3.99 you can enable the Advanced Mobile Security bundle, which expands the app’s protection:

• Enhanced caller identification and reverse-number lookup to help identify unknown callers
• Safe‑browsing tools and protections for risky websites
• Continuous identity-monitoring services to detect possible misuse of your information
• Encrypted protection when you connect to public Wi‑Fi networks

Suggested alternative: Streisand (free) may be an option if you prefer a no-cost substitute.

How to get started

• Download the ActiveArmor app from the App Store and accept the terms of service to begin setup.
• The app requires a device running iOS 13 or newer.
• Standard data fees from your carrier may apply for downloads and app usage.

Compatibility and limits

• Many features are available for both consumer and business wireless accounts, but your plan and device must meet eligibility requirements.
• Some functions rely on AT&T HD Voice and might not be available on non‑AT&T lines or older hardware.
• A few protections may be limited or disabled while roaming internationally.

Bottom line

ActiveArmor is straightforward to use and combines call management with basic device- and identity-protection tools. The free tier offers useful safeguards for everyday use, while the $3.99/month upgrade adds privacy and browsing protections for users who want a stronger layer of security.
