The issues that I brought up were escalated very quickly, and then the backend team was very knowledgeable and quick to get responses to me and help me fix my problem, but there still is the outstanding issue of trying to hook up the eSIM number to use in conjunction with iMessage.
Telnyx has been absolutely wonderful so far in terms of communication and service. Very glad to have switched over from twillio for better pricing, only to find better customer service as well. Very pleased.
Our Telnyx support representative helped us resolve a billing issue where our account owner was no longer available. We were able to update our payment method and resume usage of our phone numbers within the same day. The rep was patient and answered our questions, provided screenshots, explained our balance, and followed up via email when I requested it.
Bad service , very bad ,
They are very strict ... Very complicant ...
I hope this service get away of the internet

The sign up process has arcane steps and requirements and seems to hide the way to complete them.
The customer service appears to be a bot that gave me instructions that are physically impossible to complete via their UI.

I bought credits and bought local Lithuanian number, completed multiple verification steps, multiple tiers, and submitted extra documents for that phone number and it under review from July 13, today is July 27, I wrote to their chat bot, 0 response, estimated review time is up to 72hours. Looks like a scam company that just stole money and don't reply and communicate

EDIT: After the review things got instantly sorted, still 3 stars for the reason that things only moved in the right direction when review was submitted on trust pilot

Really positive experience with Telnyx technical support overall — responsive, willing to dig into logs and re-test with us, and issues got properly root-caused and fixed rather than just closed out. Would recommend working with their support team
Telnyx already provides great infra for our enterprise needs, but their customer experience team is just fabulous. They are fast to reply, solve problems with minimal back-and-forth and are overall pleasant to work with. I run many other services from competing telephony providers and they have by far been the easiest to work with. highly recommended!
Their support AI answers quickly, completely, and concisely - very impressive. Then, it knows when to escalate as well. API has been easy to use so far too.
Thank you for looking into this, following up, and approving my account.
I have sent an email to the email specified as requested to process the $10 refund for now. If I need to use the service in the future, I will definitely reconsider and make a new payment.
Thanks for resolving the issue!

I contacted Telnyx Support with a fairly complex question regarding Italian number requirements and the use of numbers for managed services.
The team took the time to understand the business model, escalated the request internally and provided clear written answers. In particular, Maheshi and Sam clarified that our company can reuse its Requirement Group for Italian number orders and that no additional Telnyx documentation is required from our end customers.
Their responses helped us resolve an important compliance concern before developing the service. Professional, helpful and greatly appreciated.
While integrating my system with Telnyx I frequently require precise information regarding their terms of service and integration manuals. Their response time is amazing and the information is always on point, recognizing my pain point immediately and addressing it.
Also, their AI assistant for documentation is amazing, saves a lot of time while analysing for new features. And their AI agent skills are also extremely useful while working with coding agents.
Would recommend and already did, 10/10.
The support is pretty fast and great. And the platform does what it promotes and this at a very reasonable price.
Very easy to get setup, and very clear/transparent pricing. Their AI assistant is very useful, can genuinely answer questions about your account and setting up 3rd party applications etc.
At one point I got locked out and had to email their support team, it was ironed out within the same day.
They just don't reply. Multiple follow ups and emails got me nothing. A poor email eventually arrived and then once again nothing. Several days later I got a call by someone who said all the right things, they apologised and then once again nothing. No follow ups, no replies and no email to proceed like promised. They talked up their infrastructure, said they were the best and fastest but their customer service certainly is the worst I have seen. If I treated potential clients like this, I would be broke and my business would be shut.

Great customer support from Diego and Nestor.
Some of the best i have received in a very long time.
Telny’s support is S****
If you have a request to make, you need to wait at least 24 hours.
My account is currently suspended, I have changed my corporate credit card.
I can’t even pay my bill, so I’m in maintenance.
MEGGA,
