Overview

• Since its May launch, Vodafone’s Spam-Warner has warned users about 15 million potential scam calls, averaging 150,000 alerts daily and peaking at over 650,000.
• Clever Dialer reported a 23% jump in spam calls in July, with the top ten spam numbers recurring from Hamburg, Düsseldorf and one Dutch line.
• Automated robocalls are used to verify active numbers for sale or identity theft and to trigger costly callback traps.
• Fraudsters leverage AI-driven voice cloning and caller ID spoofing to mimic official sources and increase success rates.
• Despite tools like blocking apps, the Robinson list and carrier filters from Vodafone, Deutsche Telekom and O2 Telefónica, comprehensive protection remains out of reach.
