The record

Spam call blocking: Firewall uses a whitelist based on contacts to decide which callers ring through; unknown callers can be screened to voicemail.
Caller identification: It checks callers against multiple databases for robocalls, known spam or spoof callers, and telemarketers, and may return a person's name when available.
Voicemail transcription: Firewall transcribes voicemails so users can read messages from screened callers.
SMS filtering: The site says Firewall blocks unwanted SMS spam from scammers and marketers.
Calling options: The support pricing page says the subscription includes calling from a temporary number and customizable voicemails.
Contact privacy: The site says contacts are used only to whitelist calls, are not stored on its servers, and can be deleted by the user.
Setup requirement: Firewall setup forwards the user's phone number to Firewall so it can screen calls and pass selected calls through to the phone.
Carrier support: The site lists Verizon, T-Mobile, Sprint, and AT&T as supported providers.
iOS availability: The site says robocall blocking is currently supported only on iOS devices.
Android availability: The Android page invites visitors to sign up for notification when an Android version becomes available.
Data usage: Firewall uses the phone's data plan for calls rather than the minutes plan, according to the homepage FAQ.
Support: Firewall has a support center with articles covering setup, calling, whitelist, settings, accounts, subscriptions, compatibility, and privacy.
Trial functionality: The support pricing page says the free trial includes the full functionality for blocking robocalls, including whitelisting, temporary-number calling, and custom voicemails.
Price from: $3.99/mo
