Seeking Data Providers for Italian Mobile Market Challenges

🇮🇹 Anyone working on ITALIAN MARKET ? 🇮🇹 Hi everyone, I'm working on the italian market right now. I've been enriching my contacts with "mobile phone data" but my sales complain a lot saying that most of the numbers are wrong. I'm using Clay "search mobile phone EMEA" waterfall. Any ideas of data providers that work well for this specific territory ? Thanks a lot in advance 🙂
