AT&T Consolidates RCS Services on Google Servers; GrapheneOS Notes Provisioning Issues
What happened
AT&T began running Rich Communication Services (RCS) on Google servers on November 1, 2026. This means all three major US carriers now utilize Google's servers for RCS. Concurrently, contributors to GrapheneOS have discovered issues regarding RCS provisioning. Google Messages is currently the only Android application in the US capable of sending RCS, following Samsung Electronics shutting down Samsung Messages in July.

Why it matters
The RCS standard, which Google spent years promoting, was adopted by Apple Inc. in iOS 18. This adoption allowed for the rollout of end-to-end encrypted RCS between Android and iPhone in beta. The consolidation of RCS onto Google's infrastructure centralizes the modern messaging standard for US mobile users.
