AT&T ActiveArmor Mobile Security is a free app that provides 24/7 protection for your mobile device. It automatically blocks calls from potential fraudsters and flags or sends spam calls to voicemail. The app also alerts you of nuisance calls, such as telemarketers and robocalls, and gives you the option to allow, flag, send to voicemail, or block these calls. It also has a personal block list feature where you can add unwanted callers. Additionally, the app provides breach reports and helps protect your data from mobile threats through app security, system advisor, and passcode check features.
For added protection, you can purchase the AT&T ActiveArmor Advanced Mobile Security for $3.99 per month. This includes all the features of the free version, as well as public Wi-Fi protection, identity monitoring, reverse number lookup, caller ID, safe browsing, and theft alerts. The app uses the Device Administrator permission.
To use the app, you must download it and accept the terms of service on a compatible device. Some features may vary depending on your device's operating system. Data charges may apply for downloading and using the app. Only AT&T customers have access to certain features, such as auto-fraud call blocking, spam risk labeling and blocking, nuisance call alerts, nuisance call controls, unknown calls to voicemail, personal block list, and caller ID. Some features may not work while roaming internationally.
The Advanced Mobile Security version also has some limitations, such as requiring setup for public Wi-Fi protection and only allowing 200 queries per user within a 24-hour period for reverse number lookup. It also requires the "Location" permission to work for theft alerts. For complete terms and conditions, visit the AT&T website.
