Google ditched the classic SMS/MMS messaging protocol with RCS, which makes texting other Android users feel a lot more streamlined.
Text messages are still a popular way of communication, although it seems like they are being slowly overtaken by social media messaging sites such as Facebook Messenger, WhatsApp and Telegram.
With that in mind, Google moved over from the original SMS messaging protocol and has started to use the RCS platform. We’re going to be running through everything you need to know about RCS messaging, including what it is and which handsets support it.
RCS stands for Rich Communication Services. It was developed to replace the now ageing SMS and MMS messaging services. It first launched in 2007 and was then taken over by the GSM Association in 2008, with Google claiming that it was going to integrate the service onto the Android platform in 2018.
RCS works over Wi-Fi or mobile data and can only work when all participants in the conversation have access to RCS.
RCS is a lot more capable and flexible than standard SMS messaging. It’s similar to popular messaging services like WhatsApp, implementing features like read receipts, GIFs, and emojis. It can also show when a user in the chat is active or currently typing.
RCS does not come with a character limit and allows users to send files and media, making it a lot more accessible than SMS.
The main issue with RCS implementation is that Apple has not moved over to Google’s latest standard. Apple’s iOS uses its own standard when communicating through two iPhones, iMessage. iMessage has all of the features of RCS, including read receipts and emojis.
However, iMessage is only supported through two iOS devices. This means that when an iPhone user sends a text to an Android handset, it uses the standard SMS protocol, not RCS. This results in messages lacking some of these core features, and can make sending text messages feel a lot more cumbersome than using another dedicated third-party messaging service. 
At the last Google I/O Developers conference, Google encouraged Apple to move over to the modern RCS standard to make communication between these two platforms easier and more streamlined. Apple seems to have no interest in picking up RCS anytime soon, but there is a chance that the company may be forced to adopt it over the next few years, in the same vein as the EU pushing USB-C charging to be used universally.
