AT&T ActiveArmor review
A broad free call-blocking baseline for AT&T wireless customers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AT&T ActiveArmor is a mobile security app for AT&T wireless customers with compatible iOS and Android phones. Its free tier focuses on unwanted-call protection, with fraud-risk call blocking, spam-risk labeling and blocking, custom call routing, and a personal block list. It also includes device security alerts and data-breach alerts, giving AT&T customers more than a basic spam filter.
The pricing structure is straightforward. AT&T ActiveArmor FREE provides the core call-blocking and alert features at no charge. AT&T ActiveArmor Advanced costs $7 per phone line per month and includes the free features plus caller ID, reverse number lookup, public Wi-Fi protection, safe browsing, identity monitoring, and financial protection. The paid tier is therefore aimed at customers who want broader mobile and identity security alongside call screening, rather than only spam blocking.
Platform fit is the main consideration. ActiveArmor supports iOS and Android, while its service requirement limits it to AT&T wireless customers using compatible devices. The published feature set includes routing calls to allow, block, or voicemail, along with a personal block list and unlimited blocked numbers. Choose it if you use AT&T and want free baseline protection with an optional security upgrade. Customers without AT&T wireless service, or those seeking a carrier-independent app, should look elsewhere.
