AT&T phone numbers can now be added as RCS test devices
Twilio expands RCS testing capabilities with AT&T phone number support Twilio Programmable Messaging now enables developers to add AT&T phone numbers as RCS test devices, completing support for all major US carriers in the testing phase. This enhancement allows businesses to prototype and validate their RCS senders across the full carrier landscape before moving to production. Once testing is complete, users can submit compliance information to Twilio's operations team for carrier approval and production deployment. The update streamlines the RCS development workflow by providing comprehensive pre-production testing capabilities.
