### "Good long-term choice for international-facing companies" — 5.0/5

> **認証済みレビュアー** | *2026年3月20日* | マーケティング、広告 | おすすめ評価：10.0/10
> 
> **良いポイント**: Local numbers in different countries made a real difference in how clients perceive us. Inbound call volume increased because people are more comfortable dialing a familiar number. Routing those calls to a central team works smoothly, regardless of where staff are physically located. Outbound calls are reasonably priced, and call quality has been consistent even when staff work remotely or travel frequently.
> 
> **改善点**: Understanding which destinations are included in bundled minutes versus billed separately takes attention. We had a few surprises early on before we learned to check call reports more carefully.
> 
> We run a service business with clients in several countries, and we chose Zadarma mainly for international numbers. Over time, we expanded our use to almost all phone-related communication.
