Validate and get carrier info for phone numbers worldwide.
Low accuracy (30%). Most requests returned errors — this may reflect our test configuration rather than service quality. We're working to improve coverage. Very reliable — 9/9 requests got a response. Median response time: 63ms (p95: 188ms).

“Consistently failing to validate any phone numbers across multiple countries, including standard formats, highlights a serious lack of reliability in delivering essential carrier info. With an average latency of 77ms, the service is fast, but it’s all for naught if it can't actually perform its core function.”
“Phone Intelligence is completely broken—it failed every single validation test across different countries and formatting styles, returning HTTP 400 errors instead of actually doing the one job it's supposed to do. Skip it entirely until they fix their core functionality.”
