RCS has improved messaging between iOS and Android by enabling high-resolution media sharing, file attachments, sending and receiving voice notes, and offering better GIF support. This implementation aims to provide a better messaging experience between platforms, although some improvements are still needed in areas like message reactions.
RCS implementation offers several benefits, including enhanced media sharing capabilities, improved group chat features, advanced security and privacy options, and the ability to integrate with other apps and services3. It provides a more interactive and engaging messaging experience compared to traditional SMS and MMS services.
To activate RCS in iOS 18 settings, go to Settings > Apps > Messages. You should see a toggle for RCS messaging. Enable the toggle to turn on RCS support on your iPhone. If the RCS toggle isn't showing up for you, it's probably because your carrier doesn't yet provide RCS support on the iPhone.
