January 23, 2025 5.0 Contratación y alta muy sencilla. Configuración intuitiva con manuales que ayudan a sacar el mayor rendimiento a la centralita. Pros Software intuitivo y con precios muy competitivos. CRM gratuito incluido. Cons Nada remarcable en mi experiencia con ellos Review Source DK Daniel K. IT Infrastucture Manager Telecommunications Used the software for: 1-2 years ### "Buen Producto" January 23, 2025 5.0 Pros La facilidad de crear una cuenta desde cero y poder gestionarla uno mismo. Cons Hecho en falta poder descargar desde mi cuenta mi tarifa de coste de llamadas, ya sea en Excel o CSV. Review Source Response from Zadarma January 24, 2025 Thank you for the feedback! VR Verified Reviewer CEO Education Management Used the software for: Less than 6 months ### "Terrible implementation, but worst is their inconsistent price!" September 10, 2024 3.0 Terrible experience. From the beginning it was very difficult. I am very angry at companies that are not transparent with their clients just to have a bit more money at the end. I think that Zadarma has to work first and foremost on their core values as a company. Pros After a long process, it worked and I could do good voice calls from my cellular with their terrible app. Cons I hate when companies have an inconsistent price. They have price in dollars, but for one reason my account was in Euros but my prices where HIGHER than in Dollars - Why? Because Zadarma is Zadarma and those are their values. The prices are high, we wanted to try it but it quite expensive. Terrible app on Android. Very hard to implement. Very hard to find the recordings - it's not intuitive. Problems on their website - I starter registering a phone number but it didn't do that. Even the person on the help center knew that they went too far when they started to steal my money, he didn't care to let me go and didn't offer to make things right. I talked about values - here it is. When a company doesn't have good values, this is what happens. Review Source Dmitriy P. CEO Food & Beverages Used the software for: 2+ years ### "Account offline without a proper warning " December 24, 2023 4.0 Used the service for over 7 years prior to that. Pros Hello, After being a customer for many years I have received a request for verification stating that I need to upload a copy of my passport and until I do none of my numbers are functioning and balance can't be topped up. I have completed verification in a timely manner, but account is still offline. During this period none of the incoming phone calls are routing to our numbers. I have been a loyal customer for over 7 years and never had any issues with your service. What's going on and why you make it impossible to use the service during the verification process? I am also especially concerned with the number expiring soon that we are unable to top up balance for . If it expires - how can we get this number back? We have invested our advertising budget into this and can't understand how such business practices can be the thing of today without regard to customer's needs, especially in the busiest time of the retail sales season ! Cons Poor customer service and endangering our business in the busiest time by turning off service without a proper warning Review Source DO Daniel O. student Used the software for: Less than 6 months ### "Poor and Unreasonable Customer Service Initially" March 28, 2018 3.0 I was able to receive International SMS from Israel cheaply. The account verification process and the support ticket process are cumbersome and wearisome to pursue. Pros The Zadarma Projects provides cheap virtual numbers and free SMS reception service on those numbers. After much pushing and continued engagement, I was finally given good customer service. Cons Zadarma numbers work on a monthly subscription basis. However, they will block use of certain features of your virtual numbers. This happened to me, creating a situation in which I was paying for a virtual number, but could not use the free SMS reception feature associated with it. For five days, the Zadarma support team refused to extend my subscription length to compensate for the time which they had blocked this desired features of my number. Interaction with the Support Team was extremely frustrating and slow. They would respond to me once in every 24 hour period, and their responses were unhelpful. They repeatedly said no in multiple ways to my requests. Once I gave up perusing the support team for compensation and asked to be referred to management, I was given excellent customer service. Management unblocked the desired feature of my number, and extended my subscription to one month from that day. The blocking of account features has to do with the Zadarma account verification process. They request the uploading of passports or ID cards. I uploaded my ID card on day one, and my passport on day three. Both were rejected. The ID card was rejected on day two for the stated reason that it was not a passport, despite the fact that account documentation requested a passport or ID card. The passport was rejected one day five for the stated reason that the file size was too small, despite the fact that no minimum file size limit was visible to me in my account documentation. It was only after requesting to be referred to management on day five that my account was verified with my uploading any additional documents. Review Source Response from Zadarma April 5, 2018 Dear Mr Ockrin, We regret to see that you have not been satisfied with our service. We believe that there must be a misunderstanding, since your phone number and the voice features connected to that number have never been blocked. As it is clearly written in the instructions, to activate the SMS reception on your number, we require you to upload a copy of your passport. This was done on your side 5 days after you have purchased the number. As soon, as the requirement for the activation of the SMS reception was fufilled, and you have uploaded the copy of your passport, we have enabled that feature on your number straight away. In addition, we have also extended your number for 5 extra days and we did not refuse to extend your subscription length. All of the chats between you and our Customer Service representatives show that your enquiries have been answered promptly and on time. Best Regards, Zadarma VR Verified Reviewer Documentation consultant Used the software for: Less than 6 months ### "I soon came to appreciate how this VoIP contributes to efficient & economical business communication" December 6, 2017 5.0 Pros Zadarma's range of supported VoIP features provides excellent value. In particular I find that their virtual number deals make sound business sense. By taking virtual numbers, small and medium size firms are able to compete on international markets in a way previously only open to large companies. For example, from my office in the USA I can open and run virtual offices in the UK, India, Russia and many other leading business centers. It saves a small fortune in office, personnel and travel expenses while tapping into growing markets. I also find their free cloud PBX (they also call it a business phone system) brings many benefits to both the employees who communicate through it, and customers who call the firm. Since they can receive calls on a desktop computer, IP phone and smart phone, or forward these calls to mobiles and landlines, those important business calls no longer get missed. In my experience, customers certainly appreciate a positive calling experience. This significantly increases the possibility of that customer placing an order and coming back again to make subsequent orders. Finally, there is no denying that the cost savings are a big attraction. It is hard for landline service providers to compete when they have to carry the heavy costs of phone cabinet and wiring installations and repair. This VoIP service seems to me to be a much more economical choice without compromising on call quality. Cons I had some initial difficulties with the app setup but when I turned to their customer service they provided me with the help I need to quickly complete the setup. The way their app runs down the battery life was also an issue that bothered me. I contacted Zadarma and they reassured me that in the coming new version of their app they have taken care of this problem.

The support team didn't fully refund after I installed the system and used it for 1 hour to understand if it works me. I find it very upsetting that the instructions of use were not clear enough for me in the begging and where they finance team decide to charge me for half a year use instead of one month or even completely refund me for not using the system. Pros I don't need a SIM card and could do everything from my own phone Cons On small letters it says that the service doesn't send SMS messages in USA only receive one. I needed both Switched from [Tellow](https://www.capterra.com/p/193425/Tellow/) Because you can't send SMS via their solution Review Source Response from Zadarma May 13, 2024 Greetings!

Cons Por el momento no tengo quejas sobre este aplicativo. Review Source Response from Zadarma July 18, 2023 We appreciate your review.

Independent Insurance Broker Financial Services Used the software for: I used a free trial ### "Support and Implementation Instructions Beyond Poor" September 21, 2018 2.0 This may be an extraordinary piece of software but I cannot base my business on a piece of software where the support organization cannot communicate and where the installation/integration instructions cannot be reasonably followed. They need a technical person with good English skills to go through their implementation directions and they have got to have people who can speak English on their support line before I will reconsider this product. Pros Nothing. I never got it to work. The instructions and support were unacceptable. Cons I consider myself technically competent with over 30 years of PC experience. After 6 hours, one phone call and 3 support chats I gave up trying to integrate this product with Zoho. The phone call was perhaps the most revealing in that the person who called had such poor English language skills that he gave up after two or three attempts to communicate. The chat experiences were no better. Every time I got on chat they referred me to the arcane instructions that I could not figure out. Review Source Response from Zadarma November 19, 2018 Hello William, We sincerely apologize for all the difficulties you have faced when using our service. We realize that we have a lot of features that can be hard to figure out and we are working on it. For example, in October we have upgraded PBX settings wizard to make it much more convenient to use. We will keep on going and making our service easy and enjoyable to use, including PBX features and integrations with other platforms. As for the support, Zadarma has 24/7 support in 5 languages. Unfortunately, it was our mistake that in September after the webinar with Zoho our English-speaking support was working 18/6, and you have probably contacted our team outside the working hours. Currently, working hours of English support have already been increased and soon will reach 24/7. Thank you for your interest in our service and your feedback. We are sure you will appreciate all the changes we're introducing. Please, contact me if you would like a personal 1 on 1 demo. VR Verified Reviewer Administrator E-Learning Used the software for: 1-2 years ### "Outstanding Service" January 31, 2019 5.0 I have saved money by having a phone number in a far country. This also encouraged people in that country to call me easily because for them they make local phone calls. I think Zadarma is an outstanding company that must be appreciated and supported in order to continue. It did make my life a lot easier, personally and for business. And I am sure it is helping many others too. Pros I like the possibility of receiving calls on the phone number provided by Zadarma at a very economical cost (for free when I use the web phone online) and the possibility of making low cost calls to other countries. Cons The downloadable calling software did not give me a great line quality though it was OK. But then I simply switched to the online program and it works great. Review Source VL Vitalii L. CEO Apparel & Fashion Used the software for: 2+ years ### "such a dishonest company " May 15, 2023 1.0 Cons They blackmail me and suspended 10 phone numbers. I paid for them upfront.

The service is also very high. They helped me with everything and after a few hours, our software was working perfectly. Many thanks!! Pros Very good service, helpdesk and people on the phone for questions Hugh amount of extension numbers Cheap cost of calling Easy to use product Good price Integration with our CRM (Hubspot) Cons I can't find any negative points, so for me, there's no Cons Alternatives considered [Channels](https://www.capterra.com/p/141537/Crazy-Call/) Reason for choosing Zadarma Amount of users Pricing Service Review Source Response from Zadarma October 14, 2021 Thank you for the feedback!

Owner Information Technology and Services Used the software for: 2+ years ### "Exceptionally Good" February 10, 2019 5.0 Easy to use. Tons of features. Cheap international calls. High quality audio. Free sip connections. A+++ Pros We are using Zadarma Sip features for over 2 years integrated with Bitrix CRM. We weren't content with the phone solutions Bitrix offered so switched to Zadarma. Best decision we have ever made. Right now we have over 10 different numbers in 10 countries. We sometimes have hard time to connect to some countries' mobile numbers but that's normal considering the country's infrastructure. Cons Nothing much so far. Just mobile calls are a bit more expensive than others. Also, virtual numbers in Turkey expensive and can take up to 2-3 days to activate. Still, it is not their fault. Review Source Irina T. Co-Founder Marketing and Advertising Used the software for: 1-2 years ### "Ease of use is the key" September 17, 2018 5.0 Pros Zadarma is simple and easy to use. Non-tech guys will get along with it quickly. Phone calls quality is decent. Cons I found no big issues. We are a marketing agency and Zadarma gives us all we need in terms of distant calls. Review Source oN oleksander N. manager Legal Services Used the software for: 2+ years ### "The service and quality is good, While CS was poor for a while; however lately it was improved" December 4, 2017 4.0 easy to use, exception installation and application. moneywise is reasonable Pros Software, I mean the App for the I phone is great and easy to use. Softphone on the web is easy to operate, while the general menu is still confusing. Cons While App is great , However, the functionality buttons should enlarged. The activation and tune in process is still quite complicated. Recently, during the reinstallation on a new ios device I've spent 30 min myself + another 15 min with a CS. Also, the general menu is too complicated and confusing; the simpler version , like Line2.com for instance is advised. Customer service, especially voice support must be improved. Review Source Sergiy V. Senior product designer Design Used the software for: 2+ years ### "Best value for money" June 26, 2020 5.0 Quite a positive experience. We needed one system to unite several offices and easily achieved it with Zadarma. Pros The price does not depend on the number of users, we are expanding rapidly and appreciate that we do not have to pay extra for each new employee. Very easy to set up, we managed to do everything on our own. Cons We had to verify ID for some of the international numbers but it only took 1 day.

" May 14, 2021 1.0 I would not buy again. imagine the nightmare if you buy 10 numbers Pros price is cheap, and the website is understandable, a lot of useful information. Cons i bought a number and it wasn't active. customer service told me told me to wait 24 hours so that i could find out why the number i already paid for does not work. i wrote them and called them asking to raise priority of the ticket, they just mumbled the usual stuff, which didn't bring any result.

Media Director Marketing and Advertising Used the software for: Less than 6 months ### "Worst Services Ever" July 31, 2020 1.0 Worst Services Ever Pros Was easy to use via their app installed in my phone, but they can stop their services anytime Cons Never saw such an unprofessional approach form any service provider. - They require a passport as verification proof. - But now after the same has been provided they say it is not required. - When I asked which document is required, the response is "we recommend you to use some other service provider". - I was also not so interested with the services, it is just I shared the number I purchased from Zadarma to all my Client. WILL SUGGEST NOT TO GO WITH THEM, THEY MIGHT HARM YOUR BUSINESS STOPPING THEIR SERVICES AT ANY POINT OF TIME. Ticket ScreenShot: \[SENSITIVE CONTENT HIDDEN\] Review Source Response from Zadarma August 17, 2020 Dear Sunny, As discussed over in support chats and on the other review platform, certain countries require us to verify the identity of the users connecting the numbers. When this cannot be done according to the standards of those countries, we are unable to provide the service.

Pros Purchased virtual # solely to forward UK calls to a US cell phone - support has been responsive Cons call forwarding as of yet does not work. They test calls from their system which is absolutely meaningless. Calls from recruiters in the UK fail. Test call from my US land line to the virtual # also fail.

Pros Free PBX and multiple options to share lines and API Cons Once ported, our incoming calls keep cutting at 30secs. Tech support is unable to solve.

Software Engineer Information Technology and Services Used the software for: Less than 6 months ### "Flaky service, bad customer support" May 25, 2020 2.0 I purchased a virtual number from Zadarma. After setting it up on my phone with their app, I immediately started getting dozens of spam calls a day on the new number. After an unhelpful back and forth with their customer support, I was basically told that they don't know about the history of the numbers they sell and they had no suggestions other than trying a new number. My question about whether this was a common issue with their virtual numbers and whether I should expect an improvement was ignored twice. I said fine, I'll try a new number without any sort of assurance whether that would improve the situation. They cancelled my old number and its features, and then asked for more money to add the same features (SMS service) on the replacement number. Basically, don't expect any meaningful help from their support or for your phone service to be problem-free. Do expect to be nickel and dimed if you run into issues. Pros \- local virtual phone numbers - phone app for using virtual number Cons \- customer support - lots of spam calls to provided phone number Review Source RS Roman S. CTO Computer Software Used the software for: 2+ years ### "Great reliable service!" December 4, 2017 5.0 Pros This is great service which allows us to get phone numbers in multiple countries. Quality and reliability is great. We monitor all of our phone numbers and Zadarma numbers consistently show 4+ MOS scores Cons We are primarily using this as a SIP trunk and it required customer support to get this configured.
