Telnyx Reviews 

Shocking experience, correctly setup everything via their API, messages were sent and showed as delivered on their system.

Support team state delivered does not mean received, essentially every message regardless of content is blocked by the carrier.

Had to purchase two numbers and fund the account to find this out, and then to cancel they make you jump through various security hoops, despite being logged in and on their live chat speaking to them, they ask for security information that hasn't been set up or even exists, avoid this business as a platform it's the worst i've ever used

This company is associated with telephone marketing. As my number is listed on the do not call register I can only assume that they have not cross referenced this before trying to all me. An act that I'm sure they'll know is against the regulations they are governed by.
Report sent to OffCom also

whoever is using this company have been dialing from three different number between 11 am to 12 pm and say nothing. Dead silence. Except twice what sound like a computerize voice could not understand attempt to say words. I ask "STOP CALLING!!" I been reporting number to Do NOT CALL which does not affect the call continuing Numbers display 575-249-7049, 575-717-8355 575-249=7128. My location is Cincinnati, Ohio 513-574 exchange

Absolutely horrible business practices. I created an account with this company over 2 years ago but never used it because of their inferior dashboard and system. I receive CONSTANT e-mails from them which are unwanted. Their system wouldn't allow me to login to my account to delete it and STOP the e-mails so I contacted their support. After a long phone conversation, the account was supposedly CANCELLED and they confirmed I wouldn't receive any more e-mails. About 30 minutes later, I received another e-mail. I will now have to file a complaint with both the Attorney General and FTC for their violation of the CAN-SPAM act.

Keven is my hero! I spent a couple of weeks struggling to get through the complicated verification process, but he helped me get it across the finish line.

I'm glad that y'all have things in place to protect people from spammers and scammers, and great support people to help us real people and good actors to make it through those hoops.

This looks good. Number registration and a convenient API for sending SMS messages.
There was a misunderstanding with support.
[UPDATED] However, a customer success manager eventually reached out to me and helped resolve everything. It seems the issue was an exception.

Hello Telnyx Team,

I wanted to take a moment to express my appreciation for the level of support your team consistently provides.

Over the years, I’ve worked with many telecommunications companies, including some of the largest providers in the industry such as Twilio and Bandwidth. One thing that has always stood out to me about Telnyx is the responsiveness and dedication of your support team.

Running a company means that when issues arise, time is everything. Having access to knowledgeable support representatives who are willing to help quickly and efficiently makes a tremendous difference. In my experience, Telnyx has consistently been there when I needed assistance, and that level of service is something that is becoming increasingly rare.

The reliability of your platform is important, but the quality of your support is what truly sets Telnyx apart. I genuinely appreciate the effort your team puts into helping customers succeed.

Thank you for the excellent service and support. I look forward to continuing to grow my business with Telnyx.

I've had a great experience with Telnyx. The support team responds quickly, provides clear answers, and follows through until the issue is resolved. Number porting and account setup have been smooth, and the platform offers the flexibility and features we need for our business. Highly recommended for VoIP and telecom services.

If you are tired of not receiving any help at all from Twilio, then give Telnyx a try! The guys and gals at Telnyx will actually help you get your Brand and Campaign's up and running. For non-tech people it can be a little bit daunting, but the the support staff at Telnyx will guide you through the process and guide you through any changes you need to make. They also have better pricing than Twilio.

Great support! Quick to respond. Gave clear, easy troubleshooting tasks. Followed up with no prompting to ensure the issue had been resolved (it was on my end, so they could only see that the 2FA had been requested and sent twice). Honestly, I am a huge fan of innovation and technology, but I am a human, and it is nice and rare to feel valued and supported in a world full of machines.

I can't finish my sign up.
Because I can't finish my sign up, I can't delete my partially created account.
They keep spamming me email and keep ignoring the fact that I unsubscribed from ALL mailing lists.
Their contact page isn't working and there i no way to contact them. It feels like a data harvesting scam than a proper service.

I switched from another service and got my business profile and sms text campaign approved in at least 1/3 of the time with less headaches and better communication. (Actually the other service hadn't approved when I left, so it might have been worse). To be fair, I haven't extensively exerted their system yet, but so far so good.

I attempted to sign up to begin configuring & testing a set up. Their online registration rejected my request, so I completed a form requesting contact from sales. Telnyx has ignored that request.
Since they can't even respond in a timely fashion to a sales inquiry, that certainly bodes ill for a response from customer service if I have a problem.
I suppose I'll look elsewhere for a provider.

Our experience with Telnyx is great and we are using it for more than 5 years. One thing I like the best is reliability and never had down times so our clients are happy. Also able to get DID's for any area code our client needs. We are highly satisfied with their service and support. One thing we need to explore is their new offering AI voice solution and its seamless integration with SIP Trunk.

Telnyx has made number procurement/management less stressful with their built-in tools and easy to follow guides.

One area that needs improvement is their Support. We had received warning emails about abandoned calls. Since we own a number of phone numbers with Telnyx, we had to find the specific number that was referenced and then dig through call histories to find these abandoned calls. As none were found, we reached out to Telnyx Support for help, but they were not helpful at all. I needed clarification (in plain English) and they continually came back with telcom jargon that made no sense (as if they assumed we all are telco experts).
Finally, I reached out to their Customer Success Director and he was gratious enough to explain things in simple terms and guided me where to find the information needed.
In the end, we resolved the issues, but only thanks to the CS Director.
Telnyx, PLEASE train your staff on customer interactions and human response.

I don't recommend this company.,.

The service is exteremly slow. I opened a support ticket and they just made me talk to their stupid and hopeles AI chatbot the whole day. Then they reply with some generic answer. Don't trust them. Just see the other reviews and check for yourself. Running a business myself I KNOW what customer is, and I can tell you. They don't have ANY of it.

The porting process from VoIP Innovations to Telnyx was easy, simple, and very quick. The Telnyx team provided clear, well‑structured information throughout the entire process, making the transition smooth and hassle‑free. Overall, the communication and guidance exceeded expectations, and the port was completed without any issues.

Absolutely ridiculous support and bad product delivery. Bought a Dutch national number and is still not working after TWO WEEKS! Because of a carrier routing problem. Can you imagine that? Which means Dutch numbers aren't working with Telnyx already for that (or longer) period! Their ticket system is trash, sends multiple closing issue notice mails for same ticket.
Support (must be outsourced given their names) responses are slow and standard reply, and ask you for logs to proof what's going on, hahaha?! Keep away from this provider! Very very bad telnyx!

Very disappointing experience with Telnyx. The number I purchased has been showing “out of service” from the start, and despite multiple attempts to get help through calls, messages, and support tickets, I’ve gotten little to no real support.
At one point I was speaking with a customer service representative and the call was abruptly disconnected. Through messaging, I was told an engineer would follow up, but it has now been over a week with no update or resolution.
For a telecom provider, communication and support should be a priority, and unfortunately that has not been my experience at all. I would not recommend this service and i am now forced to dispute the payment with the bank

Super disappointing that telnyx can reply faster to a trust pilot review faster than how they can respond to there own tickets thats been sitting for almost a week and over $60 was paid and still cant use the service.
