Zadarma 

Absolutely disgusting service. For verification they keep ignoring all documents. In the end I sent over everything: from passports to company registration, etc. And still they say the documents are unclear, while they are perfect copies. This is a scam. Stay away from this company!

Son un auténtico desastre. Pegas hasta para hacerte cliente. Huye de ellos como si vieras al diablo. Cero profesionalidad. Si buscas un proveedor que te dé confianza y trato humano este es lo más parecido a hablar con terminator (y ya sabes cómo se las gastaba).

En fin, que toca seguir buscando a ver si se les quita la tontería.

When I’m not in the office calls go directly to my mobile without anyone noticing. It keeps things professional and avoids missed leads. I also like that I can schedule time slots. It’s flexible and works exactly how I want. Simple but super useful.

Apparently we can not order a virtual phone number if we are not living in the country. But I could get a refund.

Before using Zadarma our agents had to copy call details manually into our CRM. Now it’s automatic and error-free. It may sound small but it saves hours every week. You realize how useful it is once you stop doing things by hand. Worth every euro.

I opened a ticket and got a human reply in less than an hour. The agent didn’t sound robotic or scripted at all. They even followed up later to check if everything was still okay. That’s the kind of small detail that builds trust. Rare these days really.

I have been using Zadarma for a few years now. It is connected to my private asterisk server as a PSTN trunk with a local number. No problems or issues since then. Everything just works silently. Good that the outgoing calls have correct CallerID in Europe. (I had a problem with another sip provider, broken CallerID after new regulations). Thanks, Zadarma (not an ad, real thanks)

So this their service was being promoted as a possibility to have a virtual number in a Ukraine, while you YOU DON'T LIVE THERE. That way you can transfer sms to your email.

After you register, they start asking all sort of ridiculous documentation without explaining why. When you ask why, they respond with a generic canned response.

I sent the following:
- Canadian mobile bill to prove address in Canada
- Full Ukrainian government ID (somehow you need be Ukrainian and have an address in Ukraine for the service, never explained)
- A official electricity bill to prove address in Ukraine (my wife has an apartment in Ukraine). That bill is sent every month by the building management team , it contains full name, address, electricity used, and required payment.

Then their support rejects my application with the following text:

"The provided document wasn't accepted.

Please provide a confirmation of the specified address. It can be in the form of any document (electricity, internet, or phone bill, etc.) that includes your full name, address in Ukraine, and a date. Receipts and bills must be dated within the last six months."

Then I ask why is my utility bill is not accepted it's an official one, I get the following response:



"Unfortunately, connecting the number is not possible without uploading a bill (electricity, internet, or phone bill). Please let us know if you want to cancel the order."

They have no competence whatsoever in dealing with customers. They can't even give an explanation on why the bill is refused. When a company responds to to customers with a canned response, it does not value them.

Also, if someone does not live in Ukraine and wants A NUMBER, why would they already have an internet and phone bill in Ukraine!? They want a number because they don't have one!

So here's the thing, my wife's condo management no longer accepts payment from foreign credit card. A Ukrainian bank account is required. Her Ukrainian bank is no longer active because it needs a Ukrainian phone number, which she doesn't have anymore since she moved to Canada. And to get a phone number, from a company like Zarma, YOU NEED A UKRAINIAN PHONE NUMBER.

When we transfer money to Ukrainians living in Ukraine to pay for my wife's utility bill, Banks block t heir account.

It's a catch-22 situation. Ukraine, and their companies are trying to force Ukrainians to go back to the country through dishonest, frankly should be illegal means.

------Update (Answer) ------
You refused a document without providing a reason. You asked for a utility bill, we provided one and you refused it. You wrote "verification requirements are set by local legislation".

If the utility bill I provided is not accepted because of some "legislation", then your government should tell the companies in your country to provide proper utility bills. This is an official bill from the condo management company .

Anyways, not accepting an official document and not explaining why, is not proper service.

I guess I'll try Yesim next, they offer Ukrainian virtual numbers without the nonsense requirements.

Años utilizando el servicio, más de 450€ de saldo en la cuenta y de buenas a primera nos restringen y piden verificación sin ningún motivo aparente. Mientras tanto, y con una comunicación nefasta con el equipo de zadarma, no podemos ni recibir ni emitir llamadas y los clientes cuando nos llaman reciben el aviso de que el número no está disponible, dañando nuestra imagen (nos han dejado reseñas negativas en Google incluso, a causa de esto).

Me ha costado horrores y muchas, muchas horas de espera que vuelvan a habilitarnos los servicios, pidiendo todo el tiempo verificaciones que carecen de total sentido lógico.

Bought a mobile number with SMS specifically for WhatsApp registration. Didn't work from minute one.

Support's response: "Contact WhatsApp support about our number" and refused to even send a test SMS to verify their service works.

Asked for immediate refund since the service is defective. They refused, claiming "1 month minimum usage" even though I had the number for less than an hour and it never worked.

Classic bait-and-switch: sell SMS-capable numbers, then claim "we can't guarantee third-party services" when it doesn't work.

Filing chargeback. Avoid this company completely.

I wasted money on this service, and it was a disappointment from start to finish. The number I purchased didn’t work for the one basic thing I needed it for, and even with screenshots proving the issue, support basically brushed it off and gave me the usual copy-paste excuses. Super unhelpful, zero accountability. The website itself feels like it was built a decade ago. Nothing is intuitive, everything is buried, and simple tasks take way longer than they should. If you enjoy spending time on a clunky, confusing platform that barely communicates what’s going on, this might be the place for you. As for reliability… don’t count on it. If you want something unpredictable and non reliable, you should go with them. But if you want something that actually works when you need it, look somewhere else. I regret signing up and won’t be using their service again.

I had been a loyal Zadarma customer for over five years, and unfortunately, my experience took a drastic turn for the worse this past year. Without any reasonable explanation, the company disabled my ability to connect new numbers, claiming restrictions related to Russia, North Korea, and other sanctioned regions. This makes absolutely no sense, as I live in the United States and have no connection whatsoever to those territories.
What makes the situation even more unacceptable is that I had already paid $500 for a yearly service plan. Despite this, Ladarma provided no practical solution, no clear justification, and no respect for long-standing customers. Their actions feel careless at best and misleading at worst.
My advice is simple: be extremely cautious. Based on my experience, I strongly recommend staying far away from this company. Their policies are inconsistent, their communication is unclear, and their customer support fails to address real issues.

La calidad de las llamadas es muy mediocre y el servicio de atención mucho peor.
Habiendo saldo por un error el la recarga suspendieron la cuenta sin previo aviso.
mas de 30 minutos esperando para que me informaran y solucionar el problema y mientras tanto en mis clientes escuchaban el mensaje de que ese linea no existe. Empresa no apta para un negocio serio

Pour le paiement, tous c'est bien passe, mais on me demande mon KBIS et une facture de tel pour confirmer mon adresse, non acceptees, je ne comprend pas pourquoi??
Service commercial incompetent, suis en attente de remboursement, voyant leur lenteur, je ne pense pas etre remboursee

I had a very disappointing experience with Zadarma’s verification process. I tried multiple times to verify my account using my Kenyan National ID, which is the only government-issued identification I currently have. However, the system rejected it repeatedly, and support insisted that a passport is the only acceptable document.

I even offered to provide additional verification documents such as my Tax ID or Birth Certificate, but they refused to consider any alternatives. The support team simply told me that if I don’t have a passport, my order would need to be canceled.

It’s extremely inconvenient and frustrating that Zadarma has zero flexibility for users without passports, especially when many telecom providers accept national IDs for verification. Their rigid approach and lack of practical solutions made the experience poor and unnecessarily stressful. I cannot recommend Zadarma to anyone who does not have a passport, as their verification system is limited and not user-friendly.

We have staff in France, Spain and Germany, and being able to set the admin panel and mobile app to each person’s native language reduces mistakes and confusion. It’s a thoughtful detail that makes a big difference in day‑to‑day operations. Everyone feels comfortable using the system, regardless of language proficiency

On holidays or company retreats, we need to let callers know we’re away and when we’ll return. With Zadarma, we record a special greeting, schedule the dates, and route calls to voicemail. Clients know exactly what to expect, and we don’t have to manually change anything the day before. It’s one less thing to worry about during busy holiday preparations.

Extremely inconvenient service, customer care, or uncare, and respect.

I made an order of business line for my startup, and selected a special number.

To set up the phone number and make it functional, they asked for a bill of utility for the business, which is a brand-new business.

I told them we have subscribed to a utility and are waiting to receive the bill, which will be provided once it's received shortly, since it's a startup.

For no reason, without any confirmation, they cancelled my plan and banned my account from gaining numbers.

They wanted to regain the special number I selected, and so they have no care for anyone who wants to use their service.

It's really inadvisable to use this platform.

Take care of your matter and don't get their service.

I imagine how difficult to deal with them; moreover, if you have a business number that your clients used to contact you on, Zadarma can cancel it at any time and ruin your business !!!

We launched our SaaS product from a coworking space with limited resources. Zadarma gave us virtual numbers in multiple countries, an IVR system, and call routing for a fraction of the cost of a traditional phone system. Clients perceive us as a larger, more mature company, which builds trust. It allowed us to punch above our weight without blowing our budget.

very poor service
can't go calls waste of time
waste of money
