Complete US Carrier Coverage for RCS with AT&T Integration

Twilio has expanded its Programmable Messaging service to fully support Rich Communication Services (RCS) across all major U.S. carriers, including AT&T, Verizon, and T-Mobile, enabling businesses to engage customers with app-like messaging experiences directly in their native messaging inboxes. This integration allows brands to scale their rich messaging strategies nationwide, offering enhanced content and interactivity without the need to manage fragmented workflows. Twilio's platform automatically upgrades messages for RCS-capable devices and falls back to SMS/MMS when necessary, ensuring seamless communication. The activation process for Twilio RCS is simplified through the Twilio Console, with zero code changes required for existing users of Twilio Messaging Services. While the approval process for RCS senders remains manual and can take a few weeks, AT&T test-device support is expected to be available in early 2026, facilitating broader testing capabilities. This development positions Twilio to deliver dynamic, scalable conversations that enhance brand trust and customer engagement across the U.S.
