Re: T-Mobile users are not receiving MFA SMS messages sent via Twilio
Hi Ian! Okay, got it. I shared with my team and we have a couple thoughts. Like your team member said, Twilio errors 30003 and 30006 are in relation to the receiving handset not supporting/not being able to receive an SMS. They unfortunately can't confirm if it's a provider issue just based on this info. If you want to connect offline, we're directly integrated with the OSR NetNumber and have a tool that can confirm if the above is true about the given numbers. Sorry, some of these issues are so nuanced (or seemingly). We can also dig into the 100K monthly messages - we're not familiar with such a limit from the carriers or The Campaign Registry, but more than happy to review and see what can be uncovered! Sorry you're having this issue, we know how frustrating this can be.33Visto0likes0ComentariosRe: T-Mobile users are not receiving MFA SMS messages sent via Twilio
Hey Ian, my team has talked to quite a few people sending business text messages that have had issues with dropped or blocked messages on T-Mobile, too. As you may already know, T-Mobile has a daily cap for application-to-person (A2P) text messages. Twilio and many other API providers "lift the ceiling" when sending messages to T-Mobile end users because they don't have a way to properly queue those messages, which can result in messages getting flagged as SPAM and blocked. One way I know this is because Twilio has a 30023 Error Code on their site for A2P 10DLC messages hitting their daily T-Mobile cap. If Twilio queued messages, they wouldn't need a preemptive error code… I hope this helps! I work at Telgorithm, please let us know if we can assist you further!31Visto1like0Comentarios
