Awful, slow response times. Have to show them all sorts of id and jump through all sorts of hoops. The only thing they did quickly was take a payment

I hit an account issue on my first day with Telnyx. I rang the NOC and got straight through to an engineer. He took ownership of it, pushed it through internally, and had it resolved within a few hours, so I was up and running by early afternoon. I’ve worked in telecoms support for 20 years. That’s the standard I hold myself to: one person owns it, they chase it internally so the customer doesn’t have to, and they fix it fast.

Genuinely one of the best experiences I've had with a telecom provider. We recently switched to Telnyx for our business, and managed to get both calling and two-way SMS fully operational in just under a week. That's including verification processes, a few compliance rejections, and the time spent getting everything integrated with our own platform. The dashboard is clean, straightforward, and actually makes sense. The APIs are well documented, integrations are relatively painless, and things generally work exactly as you'd expect. Coming from another provider where even the simplest tasks felt unnecessarily complicated, the difference has been night and day. What really impressed me, though, was the customer support. We ran into some confusion regarding 10DLC billing after an unsuccessful campaign registration. There was initially some conflicting information, but the team eventually explained everything clearly and offered $30 in account credit to cover the fees. I didn't have to fight for it or go through endless escalations. They genuinely seemed interested in making things right. Support has also been remarkably responsive, typically getting back to us the same day or the next. After experiencing support delays of weeks and even months elsewhere, that's something I genuinely appreciate. **Of course, it's still early days for us with Telnyx**, so I can't speak to the long-term experience just yet. But so far, I've genuinely had nothing but good experiences with them. Even when we've encountered issues, they've been handled well, and I haven't found myself regretting the switch for a second. Our calling and SMS integrations are now working flawlessly, and the overall experience has exceeded my expectations. It's refreshing to deal with a company that offers a solid product, a usable interface, reasonable pricing, and support that actually cares about its customers. Very happy we made the switch, and I'm looking forward to a long-term partnership with Telnyx. **Well-deserved five stars!**

I asked specific questions about porting in my region. Was told everything was in order. Set everything up. Then I couldn't Port. What a waste of time.

Telnyx support is extremely responsive to programmers and developer's issues. They are professional, knowledgeable and timely. They help you push your product out efficiently and in high quality state! I much prefer this team to Twilio, and have been seeing my bottom line improve since I switched! The service and solutions are excellent!
