According to Apple, RCS will 'work alongside iMessage' and enhance communication between users of Android and iPhone. iMessage will remain the default communication between iPhones, with RCS replacing current SMS and MMS standards. However, SMS and MMS will still be available as backups when needed.
RCS, a communication protocol designed and implemented by Google, has been adopted by manufacturers and carriers worldwide, but Apple has been reluctant to adopt it. Google has pushed Apple to accept RCS through an extensive advertising campaign involving billboards, websites, media pressure, and more.
Android users will now be able to interact with messages from iPhoneCompared to MMS and SMS, RCS supports higher resolution photos and videos, audio messages, and larger file sizes. It also adds enhanced encryption features for conversations between iPhone and Android users, cross-platform emoji reactions, and increased reliability for group chats across different devices.
In the near future, when Android and iPhone users text each other, they can interact, send photos, videos, emojis... much like texting via iMessage between iPhones.
In the future, Apple plans to collaborate with Google and other members of the Global System for Mobile Communications Association (GSMA) to further improve RCS. RCS support will be introduced in a software update next year, and carriers will need to deploy support for full functionality.
