I Don't recommend this site i had a problem with accepting my document. they did not want to accept it and when I asked for a refund they did not answer
Response from ZadarmaMay 14, 2020
We are sorry to hear that.
ID verification is a requirement for numbers in some countries and we issue refunds upon the request. Refunds are always issued upon request.
Unfortunately, you have not replied to the message sent via this platform, so we were unable to investigate the issue.

I don't usually write reviews but this…
I don't usually write reviews but this solution is just no good. The calls kept dropping and/or would not go through. We tried in different locations, wifi, and devices. Same problem each time and over multiple days. We contacted the Support team and they said "our last answer was - try to call those numbers once again". Tried again the following day and the service was still slow and unhelpful. Asked if I can have a refund and they don't respond (to three messages sent). There are loads of better solutions out there - try those.

No Reliable Support - Hidden Request After they take your money
Hidden Request. Copy Paste responses. Not in anyway to what you wrote. This is one of the worst people out there! After they have your money they will bring all sort of scripted responses. You will request ID Card, Passport and Driver License to enable sms feature, I provide Drivers license, They say provider cannot accept drivers license, PS : In situations when national legislation requires it, Zadarma has the right to request additional user information: documents proving residence; scanned copies of identity card; user's photo with a document in hand (with a sample of the handwriting) and other data at your discretion and discretion of Zadarma.
Are these Document required by you or the provider ?
Response from ZadarmaMay 6, 2020
Thank you for the feedback.
One of Zadarma's key values is transparency. Information about ID verification is readily available on the website. We operate in accordance with countries' regulations and require ID verification only if it is a necessity.
Unfortunately, you have not replied to the message sent via this platform, so we were unable to investigate the issue.

Performs great for our Vietnam team
Performs great for our Vietnam team. The same cannot be said of other providers we have used in US and UK. Great pricing on virtual numbers. I found the routing logic took some getting used to on the FREE PBX, but it does offer all that I need. Free call recording is a definite +. Great work from the Zadarma guys!!!

Shady business practices
Shady business practices. Hidden information that is not shown until they took your money. Highly advise against. Had to ask for a charge back.

Recommended. Happy about zadarma.
Ok, so giving one with initial start, depending on service over time, might come back, but if no reply, assume it's all good.
So, Seeing several here indicate a good experience with pbx/business accounting more, yet several really opposing/questioning the validity of the 'ID/Documents' process, I will give some feedback here. There is some truth to it on both sides.
First of all, I will break down some point here then make some suggestions about Zadarma, both to them and to potential customers:
1. They have lots of info on the site, how to set equipment up, English, a github repo for the API etc. AWESOME. Tons of easy stuff to navigate and intuitive info for integrations.. I am coming from a simple home user situation but a technical user in other things..
I find their site pretty awesome, and the technical availability , yet easy navigation a 9/10.
2. porting, some info can be somewhat hidden as on any site, but they do answer fairly quickly on the chat, are pretty helpful, and have good English (Bulgarian/Russian based from what I can make out).. I have had issues, which I will further expand on in a minute, but again, this was perfectly fine for me. In a world where we get used to 'automated bla bla' yet annoys us as such, it can easily sometimes be counter-annoying with some good old fashioned 'human error' but I feel this is hmm, maybe 8/10.
3. Line so far, in/out, I am being reported from my user, some busy signal now and then (will look into this as it's new and not sure if this is an issue here or on the zadarma network). Sound, etc, and posssiblities (PBX, softphones, just great and easy DIY system), are all great. Again, I will give this a 9/10
(depending on this busy thing, granted could be then less). but we are happy so far.
4. Pricing ye.. I mean, among the cheapest pricing I could find YET great interface and service (so far).. so giving this a strong 9/10.
5. Ok, now about the ID stuff.. some people here are/were worried about being Identity theft, and I myself, also worried about this! And YES, you CAN get really upset about this.. in fact, it boils down to either language OR some outdated web replies or something.. because we DID experience some manual errors and we ALSO got the ID rejected.. in our case, the ID and address given MUST be located in same ADDRESS and CITY! as the number one wants.
for "local" numbers at least.. and HERE is the issue which makes zadarma potentially lose clients and scare some :D Of course, I don't know if zadarma, as any company, might be doing something witt the ID.. but the point was, instead of being told "You have not chosen a local number in your city", or making it very clear one MUST have this.. one just got a reply with "ID was rejected".. so one things WHAT? and it just states, try making ID like this and that.. ignore all that.. I mean , make the ID proper, as they say with Zadarma and date and so on, but IF it is rejected, it is more likely this... by asking support and specifically asking what was wrong and to be honest, really ranting, did I _finally_ get the solution to the problem, slowing the process down both for us AND Zadarma.. so for this particular issue , I give Zadarma 4/10, for not having this better solved for them and for us!
But ye, if one is aware of this, and makes sure one is in the same city (or uses toll-free perhaps as I see a reviewer state), then everything else seems awesome.
Highly recommended in other words :)
Will update in 6 months or a year if I see any need to change opinion.
score 39/50, making the ID process easier and/or replying with the correct "issue" instead of the generic "ID failed" would probably make this a 8-9/10 in sign up process, hence a 43-44/50 score.
Looking forward to having you as our home system.
PS. OH, encryption however, REALLY is wanted, it doesn't seem to be there, and given how providers are all from all over, I feel this should be something zadarma and any providers should facilitate....
EDIT: to zadarma's reply: Hi, I don't mind the ID process actually. It is probably a good thing. I mean, I spent over a week asking WHY it failed. Only through chat did we discover it was due to being in a neighbouring town , it was failing. Your website just said "sorry, ID failed". This is both a misnomer and it makes you lose time, as much as customer. If you improve the 'error message' to accurately describing the "failing conditions" (be it ID, city, or whatever else), things will be much better. But, as I say, to me you look like a great choice, looking past this one issue. Thank you.

Thank you for a thorough and detailed review and your trust!
We'd like to address the point at which we need to improve. Documents that are required for number connection in a certain country/city are usually specified by local government or providers. We'd be happy to connect all numbers without any ID verification as it is done for the USA, Canada, and the UK. We completely agree that the requirement for some numbers to provide the address in the same region is the hardest to fulfill for many of our clients, that is why we are trying to offer alternatives in those places (such as national numbers, toll-free or mobile).
As for the short answers, we have sent you a private message on this platform so that we can take a look at your example and decide on how to proceed.
We are working on voice encryption, however, its set up and key exchange can be too complicated for most of our users, so we will first add it to our apps. Also, please note, that calls from our website (including the ones from ZCRM) are made via WebRTC, which does have encryption.
We appreciate your feedback and hope you enjoy Zadarma.
EDIT: Thank you for the update! There are a lot of different requirements for different countries (including addresses), but we would still like to investigate the issue and maybe find a better way of communicating for the future. Please reply the private message on this platform, so we can take some actions.
