Can't use if you vacation outside the UK
I tried to set up an account today with Maksym. I am a British citizen who lives in the UK, but I have been told that I can't use this service when vacationing outside the UK, as OFCOM forbids it!! This obviously isn't true, as so many other companies offer this service. Skip this company to find one that provides a seamless international cloud service.
OFCOM doesn’t ban British people making calls in the UK from other countries. You have taken guidance to an extreme conclusion!
Response from ZadarmaSep 25, 2025
Thank you for your feedback. We understand that this limitation may feel inconvenient, especially when travelling. However, UK telecom regulations – including Ofcom’s guidance on how UK phone numbers may be used – place certain restrictions on how outbound calls from UK numbers can be made when the user is located abroad.

Unprofessional Support, No Accountability – Avoid for Business Use
We have been experiencing a critical audio dropout issue with our Zadarma number for weeks. Calls made through LiveAgent with Zadarma SIP consistently lose audio after 90–120 seconds, while calls via Zadarma’s own app work fine.
The problem has caused serious business interruptions during peak sales season. Unfortunately, Zadarma’s support has been nothing but an endless back-and-forth. Their team repeatedly insists the issue is “not on their side” and pushes us to LiveAgent. LiveAgent engineers, however, reviewed their side thoroughly and even provided technical evidence indicating the problem is in Zadarma’s routing or media handling.
Making matters worse, Zadarma refuses to work directly with the other party to solve the problem. They will not even provide an email where debug logs could be sent for faster, engineer-to-engineer communication. Instead, we are forced to act as middlemen between two providers — a process that wastes time and delivers no progress.
For a VoIP provider, this lack of accountability and professionalism is unacceptable. If your business depends on reliable, enterprise-grade voice service, I cannot recommend Zadarma.

We are sorry to hear about the difficulties you’ve faced. According to our system checks, calls made directly through Zadarma services are functioning correctly without audio issues. The interruptions appear only when using the third-party integration, which unfortunately we cannot influence or resolve on our side.
We kindly recommend continuing to work with the support team of the third-party service to address the issue. Our platform remains stable when used directly, and we will gladly assist with any questions related to Zadarma services.

The entire experience from start to…
The company’s reply didn’t acknowledge or respond to the main pain points stated in my review.
-
The entire experience from start to finish was horrible. Their customer service reps are lifeless, and at times rude and condescending.
Both numbers I purchased were already flagged as “scam” before I even used them. (Other services I’ve used never had this issue.) When the first number was flagged, I requested a replacement. Instead of simply helping, support asked why I waited a week to report it — even though I wasn’t using that number as caller ID, I was using my own until the system stopped working with my number. So then I started using the number I'd purchased from them only the day before. All of this was documented in the support chats, but they clearly didn’t bother to read.
The second number I purchased was also flagged as a scam on people's caller ID. I tried to overlook it, but then I was suddenly asked for ID verification — seemingly as punishment for requesting the first replacement. I submitted both my driver’s license (with address redacted) and my Texas Attorney General Address Protection card (my legal address). Both were rejected with no explanation, and they never even addressed why my account was flagged in the first place.
In the meantime, I wasted hours paying my assistants while the account was blocked. After investing all that setup time, it ended up being a complete waste of time and resources. I do not recommend working with this company.

We always aim to provide reliable numbers and transparent verification procedures. Please note that all numbers are issued in accordance with telecom regulations, and any unusual activity may require additional checks or restrictions. Our support team carefully reviews documents and communicates through the ticket system, where full details are provided.

Takes 20 days to approve the number
Takes 20 days to approve the number. You'll find that out after they already take your documents and your money. If you have any business plans that require speed avoid like the plague.
P.S. The response is below from Zadarma claims some other case (probably to a person with same name), as I have first used the service on September 2nd. That just makes more evident how many such cases happen. The problem is that the 20 day delay is a surprise for everyone and is not part of their marketing package. Thankfully I got a refund and now use a service that gave me a service next day. The support person said the following to me:
"Confirmation takes from 10 to 20 days" That seems to be the problem.

Thank you for the feedback!
Unfortunately, it seems you may have misunderstood the explanations provided in the support ticket, so let us clarify once more:
1) You reserved the number on August 24, but after 10 days you wrote about a 20-day period. It looks like there was a mistake, so please correct this.
2) You stopped replying to our requests for additional data on August 30. After 72 hours without your response, the reservation was automatically cancelled. We cannot hold a number reservation for weeks without any feedback from the client.
3) You have been repeatedly offered to re-order the number, but for reasons unclear to us you keep declining.
Zadarma’s service is designed to be as automated as possible, making it simple and convenient to choose and purchase a number. Unfortunately, we cannot complete the order on your behalf. If you prefer not to proceed with a new order, we can issue a refund, which has also been offered to you multiple times.

Incompetent and Unprofessional Service
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, employee photo with passport and current date, and every requested document.
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.
Slow, incompetent, and unprofessional. I strongly recommend avoiding ZADARMA for business use.
Response from ZadarmaSep 4, 2025
Unfortunately, the process was delayed because you declined to provide the requested documents. Please contact us to complete the document submission, and we will be happy to activate your number.
