RCS 4.0 upgrades could bring video calls to your favorite messaging app - Android Authority
RCS 4.0 protocol upgrades could enable video calling capabilities in mainstream messaging applications RCS (Rich Communication Services) 4.0 represents a significant evolution in the messaging protocol, introducing video calling functionality to standard messaging applications. This upgrade builds on RCS's existing rich media capabilities—including high-resolution image sharing, group messaging, and read receipts—by adding real-time video communication directly within the messaging interface. The development signals the industry's continued push to modernize SMS alternatives and compete with over-the-top (OTT) messaging platforms like WhatsApp, Telegram, and iMessage. For CPaaS providers, RCS 4.0 adoption could expand use cases beyond A2P (application-to-person) messaging into richer, real-time communication scenarios. Carrier support and device compatibility will be critical factors determining adoption velocity, particularly as Android devices represent the primary deployment target for RCS expansion.
