It seems like a liability that I cannot disable it because I haven't done my A2P 10DLC registration in my Twilio account. I only intend it to be used in the inbound/outbound(controlled) calls. Right now it is auto-replying to my SMS messages which may put the number at risk

Set your SMS webhook to return an empty TwiML (

<Response></Response>

), and if you're sending any SMS to US numbers, you must complete A2P 10DLC registration to avoid blocking..

Seems like it's on Twilio's side, thanks for the answer. Marking it as solved

Cool
