Integrates perfectly with our CRM

we use Pipedrive and Zadarma connects smoothly. Every call gets logged instantly even missed ones. My sales team doesn’t need to take manual notes anymore. That’s a real time-saver honestly. It keeps our data clean and customers happy.

SCAM! They steal your money!!!

I registered on the website, even downloaded their app and it all looked OK, until I topped-up my account and made a call... I called the hospital that usually greets you with an automated message, and this time there was nothing, just a voice... I felt it did not sound as professional as usual, then I tried the other number - the same voice responded! After I tried the 3rd number, again - the same voice! They kept me waiting on the line for 5 minutes for nothing! Finally, they failed the last test: I called my own mobile number and got a stranger answering, while my mobile showed no incoming calls!
A bunch of thieves!

Great call routing options

You can set up rules for each department which makes the company sound much bigger. Calls go where they should without me touching anything. Once it’s configured you forget about it. It just works quietly in the background. That’s what good tech should do.

Saved me during a business trip

I was in a hotel with terrible Wi-Fi and calls still went through somehow. I don’t know how they do it but it’s impressive. The connection stayed clear enough to close a deal. Since then I trust it fully for my work calls. Totally reliable in any situation.

Suitable for freelancers and consultants

I’m a solo consultant and Zadarma gives me a professional phone setup without the overhead. Clients never notice it’s VoIP. The call quality is great even when I’m abroad. I like that I can buy a local number anywhere in minutes. It just makes me look more legit.

Helps manage call flow in peak hours

Our small call center handles about 200 calls a day and the queue system just works. You can see who’s waiting and reassign calls quickly. That’s something I didn’t find in other low-cost tools. It keeps our team calm during rush hours. Definitely worth the price.

Slightly outdated design but strong system

The control panel looks a bit 2010 I won’t lie. But it’s fast and functions well so I can’t complain much. Everything is clearly labeled even advanced options. Performance-wise it’s excellent. I’d rather have a stable service than a pretty one that breaks.

Nice tool for distributed teams

Our marketing team works from three countries and Zadarma makes communication much smoother. We use shared numbers so clients always reach someone. The call forwarding feature is super flexible. Sometimes there’s a half-second lag but it’s really minor. It’s been a game changer for our remote structure.

Outbound calls are cut

Outbound calls are cut after aprox 5 min. Each month I call my bank and often wait until human operator takes the phone. Once we approach to a solution they cut the call. It has happened infinite number of times. Most my calls have been cut. Only today I have spent 10 euros and all in vain.
Rate for the EU countries are 0.44€ per minute. Volla offers the same for o.15 €, 60% lower.

SMS messages are often lost. I never know if an international SMS has been delivered or not.

Finally a VoIP that doesn’t overcharge

I’ve tried 3 providers before and all had hidden fees somewhere. Zadarma’s pricing is straight and transparent. I always know what I’ll pay at the end of the month. Even international rates are low compared to what I used to pay. Can’t recommend it enough for small business owners

Easy to get started no tech headaches

Honestly I thought VoIP setup would be a pain but Zadarma made it super simple. The guide walked me through everything step by step. I didn’t need to call support even once. It worked straight out of the box which is rare. Been using it for 3 months and it’s been totally stable

Smart choice for small business owners

I switched from a traditional operator and haven’t looked back. The flexibility is unreal add numbers change routing all in seconds. The cost savings are huge too. I recommend it to anyone running a small company. It’s reliable efficient and honestly makes life easier.

Regular updates show they care

You can tell the company is active. Every few months new features appear or old bugs get fixed. It’s not one of those “set it and forget it” products that stagnate. I appreciate that attention. It makes me feel confident they’ll keep improving.

Absolutely disgusting service

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!

Quick learning curve

At first glance I thouhgt it would be complicated but everything is well explained. Even my non-tech colleagues figured it out fast. The help articles are clear and actually helpful. Within a day we were all up and running. It’s nice when a product doesn’t overcomplicate things.

Call forwarding feature is gold

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.

Helps us manage remote sales team

Our reps work across 4 cities and we use Zadarma to keep everyone connected. The internal call system makes coordination seamless. Managers can listen to recorded calls for training. Everyone feels like part of one system even if they’re miles apart. Honestly it simplified management a lot.

Outstanding audio even abroad

I travel often and the call quality stays the same wherever I go. Europe Asia doesn’t matter. It reconnects quickly if Wi-Fi drops. I’ve never had this level of consistency from any VoIP service before. It’s become my go-to communication tool on trips.

Integration with CRM saved us time

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.
