RCS 4.0 adds video calling, positioning carrier standard as direct WhatsApp rival

The GSMA finalized RCS Universal Profile 4.0, introducing Messaging-Initiated Video Calls (MIVC) that allow users to launch video from text threads. Built on existing WebRTC and carrier infrastructure, the specification brings RCS feature-parity with dominant over-the-top platforms like WhatsApp and Telegram. Adoption depends on carrier deployment timelines and device support, which remain fragmented globally.
