## レビュー

### "The best page for voip services and international number" — 5.0/5

> **Jhon Jaiver** | *2022年4月1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**: They have a very easy-to-use platform, the number purchase sections are very intuitive and they complement with tutorials to be able to connect everything with your phone, it allows you to redirect calls and have your phone number in the United States among other countries very easily.
> 
> **改善点**: I did not find any, it is very complete, perhaps you can expand the business to other services that are related to numbers and calls
> 
> Best of all, buy my number in the United States with a few steps and receive calls on my conventional phone is the best experience, to make calls also through voip applications you can use your conventional phone for everything.

### "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.

### "Incompetent and Unprofessional Service" — 1.0/5

> **Yevhen** | *2025年8月26日* | インターネット | おすすめ評価：0.0/10
> 
> **良いポイント**: Easy to register, but everything else is a disappointment. Maybe the pricing looks attractive at first glance.
> 
> **改善点**: – Extremely slow support — replies only every two days.&#10;– Ridiculous verification process, documents constantly rejected for no reason.&#10;– Unprofessional and unreliable, impossible to use for business.&#10;– Wasted over a week just to verify one phone number.&#10;– Overall incompetence and lack of responsibility.
> 
> We’ve had a terrible experience with ZADARMA. Since August 21, 2025, we’ve been trying to verify just one phone number. We submitted all company data, an employee photo with passport and date, and every requested document.&#10;&#10;After a week, nothing happened. Our documents were rejected because the date “no longer matched”—but that’s only because support replies once every two days\! By the time they review, the date is outdated again.&#10;&#10;Slow, incompetent, and not reliable for business. Avoid ZADARMA.

### "Helpful support" — 5.0/5

> **認証済みレビュアー** | *2026年3月5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**: Call quality is good. IVR and routing work as expected. Weise business hr vociemail to email and call recording adding new user is quick and does not required  extra set upit works fine for both office and remote staff.we contacted support during rthe firt setup they replied clearly and help us solve the issue with out long back and forth. After that we did not need much assitance.
> 
> **改善点**: The admin panel as many setting soit take some time to understand we everything is it works well but it not very modern
> 
> We have been using zadarma  for our business call for a while now.it replace a max of forwarding and mobile phones so far it's been stable

### "Simple system that helped us organized out calls" — 5.0/5

> **認証済みレビュアー** | *2026年3月11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**: Call quality, stable IVR and routing work as expected. We use business hours, voicemail to email, and call recording. It's helpful that the team can answer from laptops or mobile phones. Adding users or numbers is quick and does not interrupt anything.
> 
> **改善点**: Setup takes time. There are many settings, and if you rush, you can mis configure call flow. Other than that it has been ha great experience.
> 
> We've been using Zadarma for over a year. At first we needed one number, but later moved most of our calls there. Now it's our main phone system.
