RCS Universal Profile 2.7 introduced advanced messaging features like reactions and message editing, enhancing user experience across platforms and replacing outdated SMS systems.
The integration of RCS into iOS 18 has significantly improved cross-platform messaging, particularly in sharing high-resolution images, which was a common frustration for users.
Despite improvements with RCS, the lack of end-to-end encryption raises security concerns, particularly for enterprise users who require secure messaging for sensitive information.
Apple's messaging system provides E2EE, but this security is not available when messaging across platforms, highlighted by the use of different colored message bubbles.
