A2P 10DLC Registration Rquired
As of September 1st 2023, you must now register your Twilio phone number via A2P 10DLC.
A2P

send Application-to-Person (A2P) type messaging via standard 10-digit
long code
(10DLC) phone numbers. Carriers in the US consider all Twilio traffic
to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality
and lower filtering risk than long code SMS of the past, using the same
phone numbers.
