Ease of use is the key

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.

I soon came to appreciate how this VoIP contributes to efficient & economical business communication

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.

Exceptionally Good

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.

Poor and Unreasonable Customer Service Initially

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.

The service and quality is good, While CS was poor for a while; however lately it was improved

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.

Need to give a passport to a bulgarian company- nope

Would not recommend doing business with this outfit.

Pros

-they have a app for android that works on new android phones.

Cons

They are the unpaid police VOIP gatekeepers- No north american company or voip requires a passport for a number and SMS setup. They do. Wanted for privacy for SaaS SMS verifying. Huge headache, have not gotten a refund yet- go to any other service and you will not have to provide a passport- especially to a 3rd world sketchy back waters country.

Outstanding Service

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.

Over all good.

Pros

Easy to setup individual extensions, call statistics and charts and call geography. Incoming routes from other providers. Webphone and sms support being able to add to my own website.

Cons

Call routing fiddly to setup, unable to route calls through other providers e.g. forward to 17777123456@callcentric.com.

A fantastic service for small companies

Pros

Zadarma is a great phone system for small businesses. It's easy to set up lines, extensions and numbers and it's very reliable.

Cons

I tried portability from a UK number but they couldn't port it because the 2 suppliers didn't have a porting agreement.

Bulgarian phone in Canada

I have never had any problems dealing with Zadarma. I don't think I ever tried contacting customer service. The ability to pay for services is very easy.

Pros

We got a sip line/number from Zadarma and connected it to our VOIP phone system. Our phone system is programmed to automatically use this sip line when we dial Bulgaria's country code. I can call Bulgarian mobile numbers which would otherwise be very expensive with our local phone service. Voice quality is very good.

Cons

Calling mobile phones is still expensive. Not many of my contacts have landlines. I have tried the webphone from Zadarma's website which is cheaper per minute for mobile phones but I can't always connect.

Support and Implementation Instructions Beyond Poor

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.

Reliable and cost-effective solution

Pros

I run a company in the US (Florida), and we have customers in States and worldwide (most of them in Europe). We are exploring new markets/target audiences, and switched to pure b2b to the mix of b2b and b2c. Now some of the new customers are calling our main office (we are trying to move communication to email/chats, but that just don't often work, people want to get a consultation by voice - don't know why). So, we needed a solution to set up calls without buying own hardware/software and managing this stuff. I've come across Zadarma's site and found their rates very pleasant compared to other providers, so I decided to give it a try. For now, we are using it for several months already, and almost everything is fine: no outages, charges are accurate (and still low).

Cons

A couple of time there were situations with wrong calls when the number belonged to someone else, and people kept calling it. I had to contact support to get this fixed, however this was done very fast both times.

Great reliable service!

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. Customer support was great though.

I have been using Zadarma since near the time of their conception and they have saved me THOUSANDS !

Cost savings

Pros

Great value calls from simple to configure software - works from my contact list and integrates with my call logs

Cons

Tends to eat the battery - but I am more than willing to accept this 'problem' in return for the benefits

Very easy to use and useful product

Overall experience is great, this service is very good value for money

Pros

I use Zadarma PBX for more than a year. It's great and stable product, easy to config, with great prices and very good support service

Cons

There are several technical issues with PBX, such as lack of transfer functions integration with hardware and software phones.

good

Pros

Less expensive and friendly user. You can connect to the support when you need their assistance. Overall good

Cons

have to inform support once top up added. should have been automatic. Nothing much to say. Overall software is good

Quality Services of Zadarma project

It is a great project which for me personally has opened up my business activities in fields i was not aware at all i could do.

Pros

Easy installation, no heavy equipment, instant service.

Cons

Nothing really special. Maybe if the cost on mobiles would be little bitty lower. but in general there is absolutely no problem.

SMS delivery was not working and they refused to refund

I was trying to get SMS delivery service, however Zadarma di not work.

Pros

The VOIP calls from and to the virtual number worked. The response of the customer care is fast, however useless. |

Cons

The service I needed was not functional, Zadarma support refused to issue a refund.

Useless software

Scam-like software, don't fall for it

Pros

None, it's doesn't work property, very bad customer support

Cons

Fails all the time, terrible customer support, they take your money and then ask.

Value for money when you need international roaming

Overall I consider this a great service with very useful features.

Pros

It is very easy to get a foreign number if you got your documents right, mostly it is passport. There after you can easily divert virtual number to local number.

Cons

There were few times I noticed audio lag

Can't use services because they can't verify my number

Pros

-Absolutely nothing. I had one goal, and the system would not allow me to achieve it.

Cons

The goal was to use the product for virtual number. But my actual phone number could not be verified for some reason, and because of that they could not provide me with the service. The customer support was atrocious, it was like talking to a bot. The initial responses were same as I was getting from the online form. I had asked the operator to say "potatoes" to prove that they were not a bot.

Best solution for virtual phone systems

Pros

With Zadarma we got an amazing solution for a very attractive price. Its seems like theres nothing their service cannot do.

Cons

You need to get a hang of the website, that might take a day or two

Don't waste your time

The service is cheap, but customer service is HORRIBLE to say the least...

Pros

The service worked. Not the best set of features but it worked and the price was cheaper than I expected.

Cons

Worst customer service I ever seen in this industry. It ruined the whole experience for me. I was forced to stop using the service and switch to a different provider after 1 or two month. Wasted my time and money.

Very good Software and easy to use!

very good experience, we didn't have any problems everything works smoothly.

Pros

Very good software works perfectly in Mexico. Customer Support is great in different languages.

Cons

The ID checking process takes around 24 hours, so one has to consider the time.
