	Pros & Cons from Real Users Pros Before I found out about Telnyx I was trying Twilio, so it was really great that the Telnyx Twexit API is mostly compatible with codebases written for use with Twilio. The pricing isn't bad either. Telnyx has always been the most reliable of the phone providers we use. They are also the quickest to respond and solve problems. Prices are excellent and service offerings are fairly complete. Setup is easy and there are great tutorials for many systems. The connectivity is exceptional. We have deployed in both US and Europe. Their customer service and tech support is amazing. Excellent and ease to use and good service recommended for business/ Cons Could be a pro depending on your perspective, but I wish Telnyx didn't go for the super personalized onboarding approach - as an introvert, I hesitated when I couldn't just spin up the docs and try it out via trial and error (you have to set up a call with telnyx engineers). At first the portal UI was hard to learn to use to use. There are some things missing like a fully functional SMS client. Need to use a 3rd party client or build own with the API. Their display portal for the web connectivity report is lacking. No cons.
