The company I work for had text messages filtered about a year ago. We confirmed that we have everything correct with 10DLC and were not violating any rules or code of conduct. Our campaigns are proper 10DLC and had met the use case requirements with SBR campaign, Twilio needed to convert the NNID flag on the backend configuration to 10DLC to run our traffic over sanctioned channels. It appeared that the traffic was NOT routing over sanctioned 10DLC. It was running over consumer channels.
This was all corrected and things improved dramatically. However, something happened starting on the 21st of this month where TMOBILE (and METRO by TMOBILE) started filtering about 50% of all of our messages again. Is anyone else experiencing this or would know why this filtering is happening again?
