I recently experienced an unexpected…

I recently experienced an unexpected billing issue on my Twilio account, and I want to thank the Twilio support team — especially Cesar and Matt — for their outstanding assistance.

They took the time to clearly explain what happened, released the phone number that was causing recurring charges, and even went above and beyond by applying a goodwill credit to resolve my account balance. Their communication was professional, clear, and supportive throughout the process.

It’s rare these days to see such a customer-focused approach, and I truly appreciate the way Twilio handled my situation. Because of their help, I feel confident continuing to use Twilio for my business.

Highly recommended support team! 👏

Best regards,
Nisso H.

I am astounded at all these bad reviews.
I use there SMS service to send messaged from my various IOT devices to my cell phone. Very cheap and never a problem.
I also use there SIM for a 4G backup. This works fine too.

Full refund from Twilio for $12000

Due to some rogue code going live, a developer inadvertently put live a for-loop that sent over 100,000 SMS messages costing us $12000. Twilio made a full refund.

Six months running with excellent service and turn-up

Recently migrated to the Twilio interconnect platform to escape chronic outages and poor service from another provider.

We are currently receiving the highest call completion rates we have seen in a long time and after working in the telecommunications industry for the past decade, I have not yet experienced a faster turn up process and ease of setup than I did establishing circuits and transport to the Twilio Interconnect platform.

We found the Twilio engineering team to be very responsive and knowledgeable with their own platform and experience with on-boarding clients similar to us and the services we offer.

We also discovered Twilio's billing team to be responsive with inquiries and learning about the billing process.

The Insights dashboard is extremely helpful compared to our former ITSP when trouble shooting call completion and utilizing SIP URI calling.
The logging is clear, concise and demonstrates what the exact error was.

I highly recommend Twilio to others that only get one chance to send or receive vital calls.
