SO GREAT Great pricing Great service Even great support!!!
Roman Korenkov - R.
It all started when I needed an API telephony service that supports SIP trunking as an individual. It took me some time, but I made my choice! To make a long story short, I had a non-standard situation due to an unusual Polish passport of a foreigner, so I couldn't pass verification in their automatic verification service, however I compared competitors again and came to the conclusion that Telnyx was what I needed. I contacted their technical support and they responded immediately and then verified my account in less than 12 hours, super! At this point, I am very happy that they maintain this level of service as well as pricing.

I had a mixed experience with Telnyx, but in the end, Karl truly saved the day. Initially, I struggled for quite some time with several other team members, as they weren’t able to provide the support I needed. However, once Karl stepped in, everything changed—he was incredibly helpful, professional, and efficient. Karl is a real asset to the company! The services themselves are top-notch. The connections are super reliable and of outstanding quality. Their pricing is highly competitive, and I also appreciate the strong focus on security and measures to prevent misuse of their services. Overall, despite the initial challenges, I’m very satisfied with Telnyx thanks to Karl’s excellent support. Highly recommended!
