Zadarma — 3.5/10

Zadarma is a 19-year-old VoIP and virtual-number provider with 2M+ users across 110 countries — a perfectly trustworthy business — but it requires full mandatory KYC (passport / ID scan, selfie holding the passport, and a utility-bill address proof) before any number can send or receive SMS or calls. It earns a low score here because its identity surface is the opposite of what this directory exists to recommend.
