Freedom251 › Spam Call Blocking Apps
Firewall
What Firewall is
Firewall is an iOS call and message screening service built around a contact whitelist. Contacts determine which callers ring through, while unknown numbers can be sent to voicemail. Caller checks compare numbers with databases covering robocalls, spoof callers, telemarketers, and other known spam; a person’s name may appear when available. Screened voicemails are transcribed for reading, and the service says it blocks unwanted SMS from scammers and marketers. Subscribers can call from a temporary number and use customizable voicemails. Setup forwards your phone number to Firewall, which screens calls and passes selected calls to your phone. Verizon, T-Mobile, Sprint, and AT&T are listed providers. Calls use your data plan rather than your minutes. The Android page offers notification signup, while blocking currently supports iOS only. The plan costs $3.99 a month after a 14-day free trial, with no commitment.
