The only reason my business uses Twilio is for a custom SMS system that notifies our existing clients of certain things in the system. Our clients PAY to get these SMS. However Twilios A2P 10DLC approval process has killed our whole system and even after months of attempting to get this approved we still haven't been able to. However Twilio has NO problem continuing to take our money every month for messages that are NOT being delivered. They also have no problem charging $15 everytime we try to get the campaign approved. They can't even be bothered to tell you why it was not approved and instead just tell you it was rejected for "unknown reasons". As for their outsourced support that takes at least 24 hours between replies... well I'd have better luck asking my dog for help. If we had not already wasted a lot of time developing our system to work with Twilio specifically we would have dumped then loooong ago.
