Norwegian telecom operators Telia and Telenor want to share customer data with banks to prevent phone scams that cost Norwegians millions. They observe suspicious long calls but current privacy laws prevent them from warning potential victims. The companies reference the UK's "Scam Signal" system, which allows banks to check if customers recently had suspicious calls before processing transactions. Legal frameworks need clarification to enable data sharing between telecoms and banks while maintaining customer trust and privacy protections.
