What Callblock is

Callblock is an iOS app that blocks unwanted telephone calls and iMessage, SMS, and MMS messages. Its directory contains more than 3,000,000 telemarketers and is advertised for use in 174 countries. Users can filter telemarketers by type or choose caller ID only, which identifies callers without blocking them. Blocked calls go directly to voicemail with caller ID information attached. The maker says Callblock reduces unwanted calls and texts by more than 85 percent. Users may add, remove, or reclassify callers in the local directory and submit reports for review. The directory is compiled from public and private records, research, testing, and user reports, with more than 10,000 entries added or reclassified on an average day. Callblock does not need Contacts access, and its maker says Contacts data is not collected or sold. It cannot block calls or texts without caller ID because of an iOS limitation. The app supports 64-bit iPhones from iPhone 5s running iOS 10 or later. Subscriptions cost $1.99 a month or $19.99 a year after a free month.
