The Provisioning, Management & Compliance (PMC) team sits within Vibes’ Connect organization, the group responsible for the messaging and provisioning infrastructure that powers all SMS, MMS, and RCS delivery across our Tier-1 aggregator network. PMC ensures that brands can successfully launch and scale their messaging programs by overseeing carrier connectivity, short code provisioning, message routing, compliance enforcement, and the systems that guarantee reliable, high-volume communication at scale.
