Rich Communication Services (RCS) is a messaging standard Apple adopted in iOS 18 that is significantly enhancing the messaging experience between iPhone and Android devices. Think of it as SMS 2.0 – a major upgrade to the traditional text messaging we've been using for years.

Key Features of RCS

Apple's decision to embrace RCS came last year after persistent persuasion from Google, which has been championing RCS adoption worldwide – and with good reason. Compared to MMS and SMS, the standards that Apple uses for text messages, RCS offers the following advantages:
  • Higher quality photos and videos
  • Larger file sizes for attachments
  • Audio messages
  • Improved group chats
  • Read receipts and typing indicators
  • Better encryption for chats between iPhone and Android users
  • Cross-platform emoji reactions
  • Location sharing within text threads
  • Works over both cellular networks and Wi-Fi
RCS vs. iMessage: Bridging the Gap

While RCS offers many features that iPhone users have long enjoyed with iMessage, it's important to understand the differences between these two messaging protocols. The most significant advantage of RCS is its ability to work across different smartphone platforms.

Unlike iMessage, which is exclusive to Apple devices and creates the infamous "green bubble" effect when iPhone users text Android users, RCS attempts to eliminate this disparity, creating a more unified messaging experience regardless of device type. That said, RCS messages will still appear as green bubbles in Apple's Messages app, but they will be accompanied by the label "Text Message – RCS" in the conversation thread to identify them.

In terms of features, RCS brings many of the capabilities iPhone users have come to expect from iMessage to cross-platform conversations. High-quality media sharing, read receipts, and typing indicators – all staples of the iMessage experience – are becoming available when texting Android users through RCS. This marks a significant improvement in the messaging experience between different platforms.

When it comes to security though, iMessage still holds the upper hand. It offers end-to-end encryption for all communications between Apple devices. RCS, while offering improved encryption compared to traditional SMS, doesn't quite reach the same level of security as iMessage. However, it's a significant step up from the unencrypted SMS messages that have been the standard for cross-platform texting.

Another area where iMessage still maintains an edge is in its immediate availability across all Apple devices. RCS, on the other hand, depends on carrier support and implementation on both ends of the conversation. This means that while RCS promises a more unified messaging experience, its availability is not yet as universal as iMessage is within the Apple ecosystem.

Despite these differences, the adoption of RCS by Apple represents a major step towards bridging the gap between iMessage and Android messaging. While it may not completely eliminate the distinctions, it certainly narrows them considerably, promising a richer, more consistent messaging experience for all users, regardless of their choice of smartphone. In summary, here's a breakdown of what users can expect when messaging between iPhone and Android devices:
  • Enhanced Media Sharing: No more tiny, pixelated photos or videos when sharing media with Android friends. RCS allows for higher resolution and larger file sizes.
  • Rich Messaging Features: iPhone users will be able to see when Android users are typing, know when messages are read, and use emoji reactions in cross-platform conversations.
  • Better Group Chats: Group conversations including both iPhone and Android users will be more cohesive, with features like naming group chats and adding/removing participants working smoothly across platforms.
  • Wi-Fi Messaging: Like iMessage, RCS can work over Wi-Fi, allowing for messaging even without cellular service.
  • Seamless Fallback: If RCS isn't available for some reason, the system will automatically fall back to SMS/MMS, ensuring messages always get through.
How to Enable RCS Messaging in iOS 18

Apple introduced RCS support with iOS 18. However, full functionality will depend on carrier support. The good news is that major U.S. carriers like Verizon, T-Mobile, and AT&T already support RCS. Apple also has a list of carriers that support RCS on its website.

  1. Open Settings on your iPhone and select Apps at the bottom of the menu.
  2. Tap Messages.
  3. Under "Text Messaging," select RCS Messaging.
  4. Toggle RCS Messaging to the green ON position if it isn't already enabled.
If you don't see the setting on your iPhone, that's likely because your carrier does not yet support it. Check Apple's wireless carrier support page to check if yours is listed.

How to Tell If You're Using RCS

There's a simple way to tell that you are sending an RCS message in the Messages app. You'll see "RCS" at the top of the conversation window as soon as you type in the number of someone not using an Apple device.

The Future of RCS

Apple isn't stopping at just implementing RCS. The company plans to work with Google and other members of the Global System for Mobile Communications Association (GSMA) to further improve the RCS standard worldwide. This collaboration should lead to even more advanced features, such as the ability to edit and delete sent RCS messages.

What in the world will Google complain about now? This has been their go-to marketing dig for a few years now. Hopefully they had something as a backup.. 🤣
 
In US here and my carrier has it activated. Tried messaging on phone and via Mac to a couple of Android users and no sign RCS is happening yet. I assume it's their carriers who haven't updated or even implemented it.
 
Could they please allow us to change the color of the green bubble to something else? It would be much easier on my eyes. Reading white text on a green background isn't the best.
 
What about messaging on an iPad? There’s no RCS setting for it. Do iPad messages always send as SMS?
iPads don‘t support carrier messaging directly, they simply relay the content to your iPhone which decides what to send it with.

Messages on iPad does sync over availability of carrier messaging services though for usability (e.g. it showcases RCS in the input box, although it still wont decide what to send a message as since that‘s done by your phone).

The fact that Tim Cook allowed RCS messages to be green shows how utterly clueless he is, and how Steve Jobs was right when he complained to his biographer that Cook is not a products person. SMS messages are green. iMessages are blue in order to easily know that it is not an SMS message. Clueless Cook allowed RCS messages to be green, thus not making it easy to know if it is an RCS message or an SMS message. If Clueless Cook actually cared about user-friendliness, RCS messages would be a different color which is neither green nor blue.
Sorry but the fact that you think Cook makes these kind of decisions maybe show how clueless you are. This is a marketing strategy to keep people in the Apple ecosystem. They want people to want blue bubbles hence iPhones everywhere.

This is a good thing so that people know if you have Apple’s better encryption vs the (still better than MMS and SMS) worse encryption that RCS uses.
 
absolutely no possible outcome that RCS will be a thing since global telcos do not offer such service. iMessage will always top that. but top of it all, FBM and WA will top all of them (with Telegram, Signal and whatever else on the side)

iPads purchased with cellular modems do indeed support carrier messaging directly. If your iPad has cellular it doesn’t not have to forward texting to an iPhone.

As an Android user, I have not sent a single RCS message in my whole life so far. Why would anyone use a Google server for private communication?
What is your definition for a "private communication"? I don't think in my whole life so far that I've sent a text that I cared where someone else saw it or not. Are you using your phone for illicit activities? I mean, it's nice that an iMessage is end-to-end encrypted, but I wouldn't care if it wasn't. My texts are just grains of sand on an endless beach.

Yeah, while that may be true, when composing a message in the text box it will show the kind of messages you are working with

If it's RCS, it'll say Text Message - RCS instead of Text Message - SMS or iMessage
 
Swedish operators don't support RCS on Apple devices as King hasn't approved it yet.
 
This is only relevant in the US, the vast majority of people in the rest of the world uses WhatsApp/Line/Wechat/telegram and probably their carriers didn’t even bother with those settings, so it doesn’t appear.
 
Sadly I think it is too late. The usage of WhatsApp is such that people simply won't stop using it and switch to RCS. It has taken way too long. And not all carriers support it, people on Android don't even know about it, they just use WhatsApp....

I don't like WhatsApp, it is not carrier grade, it has too many limitations, it is not standards compliant, and ahem it is by Meta. Something as core as messaging shouldn't be by a company. But it happened as it gave what people wanted.
I don't think the goal is to draw people away from WhatsApp, it's just to improve messaging in general. It's just the evolution of SMS, which is still pretty commonly used in the States. This just brings outdated SMS up to more modern standards.

My smaller MVNO doesn't support this and when I contacted them a few months ago they didn't if/when they would. But I'm saving so much money with them over my previous Verizon plan I really don't care.

True, but SMS still exists as kind of a default backup. Even if you never use it, you'd probably think it's pretty weird if a phone/carrier didn't have a built-in way of sending text messages that didn't require a 3rd party app. RCS is just upgrading that default messaging protocol to be more in line with what those aforementioned messaging apps offer. After all, SMS hasn't really changed since cellphones first gained the ability to send text messages decades ago.

Apple still has a vested interest in having users prefer iMessages over everything else. They're always going to make any alternative less appealing, and as much as it might irritate us, it's brilliant on their part. There's evidence that shows that people switch to or stick with iPhones just for iMessage alone.

The people you message must be stuck in the past then. No offense to you or to them personally, but everyone I know that uses Android moved to RCS a long time ago. Most iPhone users I know have this feature toggled on as well.
