I love how easy Telnyx is as compared to Twilio, especially the number porting and 10DLC. One thing that I loved the most was their team first evaluates your submission for number porting and 10DLC registration and then sends it for submission to the carrier, this increases your chance of getting approved whereas Twilio sends it directly and if it fails then you lost your $20 for the submission fee.

Excellent technical support We’ve been working with Telnyx while developing our own business communications platform and have needed support on some fairly technical issues. The support we’ve received has been excellent. Rather than giving us generic responses, the team took the time to understand what we were trying to achieve, investigated the problem properly and provided detailed, useful answers. It’s particularly reassuring to know that when we need help with something more complex, there are people at Telnyx who will actually get into the detail with us. Very happy with the service and support we’ve received.

The customer service is very good. I didn't have to wait for several hours to get my answers. The telephony service is good. In one click you can purchase US, Canada DIDs and start using them

I contacted Telnyx support with questions about our outbound concurrency limits, and their team responded almost immediately. They quickly approved my increase after a quick review of my account and use case. They also answered a couple of follow up questions. Great support and a very positive experience overall!

I arrived at Telnyx with a frustration that was borderline madness. I had been trying to find a service for my Quickdiary.co.uk service and Twilio were not hospitable to a young company like mine. After a lot of searching I stubled upon Telnyx and things just went smoothly. Even when I had a support query the support agent was supportive and helpful. I am genuinely thankful that I did stumble upon Telnyx because I'm now rolling out my services and happy to have the support of Telnyx in the background.
