In a surprising move, Apple has announced today that it will adopt the RCS (Rich Communication Services) messaging standard. The feature will launch via a software update “later next year” and bring a wide range of iMessage-style features to messaging between iPhone and Android users.
Apple’s decision comes amid pressure from regulators and competitors like Google and Samsung. It also comes as RCS has continued to develop and become a more mature platform than it once was.
iMessage is a rich communication layer backed by HTTPS and web sockets so think something like WhatsApp or Telegram; you can send 2 gig files, embed maps and other rich content, etc etc. SMS is well… SMS. So the blue versus green bubble is a dumb reductionist view but the practical impact is visible in say video messaging, where an iMessage can attach a 50mb 4K H.265 clip same as a real messaging app, whereas an MMS will be a 256k 3gpp potato.
