Executive

Integration requires careful setup and even small configuration mistakes can prevent calls from syncing correctly across devices.

Manager

Outbound calls are reasonably priced, and call quality has been consistent even when staff work remotely or travel frequently.

You should monitor pricing for different destinations, and especially for outbound international calls.

We run a service business with clients in several countries, and we chose Zadarma mainly for international numbers.

Senior Executive

There are many settings, and if you rush, you can mis configure call flow.

We submitted all company data, an employee photo with passport and date, and every requested document.

Online Reputation Management

We moved to Zadarma when call volume increased and our previous setup couldn’t handle it.

We connected Zadarma to our CRM to keep track of calls.

We use business hours, voicemail to email, and call recording.

Local numbers in different countries made a real difference in how clients perceive us.

Founder and Entreprenuer

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 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 !!!

Our documents were rejected because the date “no longer matched”—but that’s only because support replies once every two days!

You need to plan your call flow before building it.

Manager can review conversation when needed.

Call quality has been stable in different locations.

Getting international numbers was straightforward.

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.

Extremely slow support — replies only every two days.

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.

By the time they review, the date is outdated again.

Executve

It's really inadvisable to use this platform.

Unprofessional and unreliable, impossible to use for business.

The prices are high, we wanted to try it but it quite expensive.

Very hard to find the recordings - it's not intuitive.

I have completed verification in a timely manner, but account is still offline.

Next to that my customers do not recognize the sms are not able to respond directly to my SMS-es anymore (the recipient cannot respond to the 'Zadarma.com' sender-id).

We use SMS to respond to customers and for that having our local (virtual) number as the sender-id is crucial.

The SMS function in the app however only sends SMS with sender 'Zadarma.com'.

Owner

I used another software before and we had a lot of bad calls, lines bad, etc, but now, we use Zadarma, the lines are very good.

Zadarma support just states that it is not guaranteed (to me 'not guaranteed' means it does not work all the time, but currently it NEVER works) which is quite unsatisfying.

The sender-id that is used currently is 'Zadarma.com', which looks very unprofessional to my customers.

More than once my recipients just discarded of my SMS-es because they did not recognize the sender.

Network Architect

They test calls from their system which is absolutely meaningless.

Director

Choosing the virtual number, selecting the features you want

Assistant Director 

My appetite for trying out different softwares brought me in contact with this app, and the experience wasn't bad at all.

Tech Sales Director 

Virtual offices in 3rd countries during COVID

price is cheap, and the website is understandable, a lot of useful information.

imagine the nightmare if you buy 10 numbers

The 3 months prepayment is not encouraging, it should be scrapped!

Not pleasant since they fail to deliver promised service.

Complex and dated navigation

Founder

There isn't really anything that I dislike about Voip.ms other than the menus can be a bit confusing to navigate because there are so many options and settings but you eventually get used to them.

Leader, IT Operations

For the novice user it's a bit harder to use and navigate for setting up your first SIP as the menu is buried a sub menu deep.

70% of reviewers feel negative about VoIP.ms’s navigation. Users think the web interface is cluttered and unintuitive, making it difficult to locate settings or features, especially for new or infrequent users. They say the menu structure is confusing, with important options buried in submenus, and the overall design feels outdated. Some reviewers report that the control panel’s complexity can be overwhelming, and the lack of modern UI standards or streamlined workflows adds to the frustration during setup or configuration.

Limited and unreliable SMS functionality

The SMS/MMS UI is often delayed, has storage time limits, and is just somewhat unreliable in general.

53% of reviewers feel negative about VoIP.ms’s SMS capabilities. Users report that SMS support is inconsistent, with issues receiving messages from short codes or certain providers, making two-factor authentication difficult. They say the SMS/MMS interface is basic, sometimes buggy, and lacks essential features like reliable delivery and effective spam filtering. Reviewers also mention that integration options are limited, rates are high, and the messaging system is not always user-friendly or dependable for business needs.

Occasional service disruptions

VOIP.MS had a DDOS attack early in 2023 that was a PITA, no fault of theirs but it still was really the only bad experience I have had in my 10+ years of being a customer.

Photographer

I wish future service disruption would be communicated sooner; when the company was hacked a while ago, we did not get any details until a number a days after service was down.

64% of reviewers feel negative about VoIP.ms’s service outage history. Users report experiencing significant disruptions during events like DDoS attacks, which have caused prolonged downtime and operational inconvenience. They say that outages, while infrequent, can last several days and impact business continuity. Some reviewers express concerns about the lack of timely communication during incidents and mention that there is no automatic failover in case of server failures, making the service less reliable during critical periods.
