What direct 10DLC registration changes
Brand and campaign registration with The Campaign Registry is handled by Messangi as the CSP of record during onboarding — no third-party reseller in the chain, which means faster vetting, direct visibility into campaign status, and one accountable party when a carrier flags traffic. The US is unusual in requiring campaign-level approval before A2P traffic flows; that registration work is part of the account, not a form left for your team.
