Overview

• Vodafone's Spam-Warner automatically displays 'Vorsicht: Betrug möglich!' for calls flagged as potential scams, protecting customers from fraud.
• The system uses Vodafone's CallerID technology and a database of thousands of known scam numbers, updated regularly to detect suspicious activity.
• While effective, the database is not exhaustive, meaning calls from new or suppressed numbers may bypass the warning system.
• The Spam-Warner is active for all Vodafone network users, including customers of other providers like Freenet who utilize Vodafone's infrastructure.
• Competitors Deutsche Telekom and O2 Telefónica are developing similar anti-scam measures, signaling a broader industry push for enhanced call security.
