PhoneBlock vs Verizon Content Transfer

PhoneBlock is a free call-blocking service that uses a community-maintained database to identify unwanted advertising and spam calls. Users can report numbers through the app, website, or personal blacklist, and reports join the shared blacklist. The Android app blocks known spam calls, keeps call history, and supports reports and personal lists; it requires Android 10 or later. For incoming calls, the Android app sends only the phone number’s SHA-1 hash and does not access contacts.

Landline users can choose a router dongle, a Fritz!Box cloud answering machine, or a blocklist phonebook synchronized through CardDAV. The documented iPhone setup syncs spam numbers into contacts through CardDAV; a native iPhone app is in development, and beta registration is available. Phone systems can download the blocklist in different formats or query it through an API. PhoneBlock is licensed under GPL-3.0 and operated as a private project. The operator accepts email requests for help, including for mistakenly listed numbers. PhoneBlock costs nothing, with donations optional; its terms advise against business use.

Verizon Content Transfer moves personal data from an old phone to a new one. It transfers contacts, photos, videos, calendars, call logs, and audio between Android and iPhone devices. Pairing uses a QR code, and Verizon’s Android instructions require Wi-Fi on both phones. Transfers are described as end-to-end encrypted, with data encrypted in transit. The app reports progress in real time and can resume an interrupted transfer. Contacts and media already backed up to a cloud service are not moved by this process; they must be restored through that service. Android instructions direct users to the Play Store when the app is not already installed. The iPhone listing requires iOS 15.0 or later, and the iPad listing requires iPadOS 15.0 or later. Verizon lists a free plan with download from the App Store and no wires, accounts, or cloud required. The pricing note states paid plans from $3.99/mo and a 15-day trial, while the free-trial field says no.
