Overview
- The measure marks the second phase of AGCOM’s crackdown, extending August’s fixed-line anti-spoofing filter to mobile prefixes that mimic Italian numbers.
- Operators will verify that a number exists, identify its assigned carrier, and confirm whether the SIM is in roaming; calls that fail these checks will be blocked automatically.
- AGCOM estimates roughly 50 million spoofed mobile-type calls each month, while consumer group Codacons reports about 15 billion unwanted calls per year.
- Officials caution the mobile filters are technically harder to run in real time and will cut, but not eliminate, spoofed and nuisance calls, with coordination among all carriers required.
- Operators that do not implement the filter risk losing the ability to offer roaming until compliance and must give customers one month’s notice, with AGCOM saying the process preserves user privacy.
