For years, the iPhone’s two-tiered texting system has been a sizzling subject. iPhone-to-iPhone texts within the Messages app are blue, and luxuriate in full encryption and extra sturdy media options, like animations. However messages to and from Android units are merely commonplace SMS texts, and marked with a inexperienced tint. Apple’s segregated messaging platform has been the topic of a , and even sparked chatter of regulatory intervention. However with Apple’s current affirmation that it’s going to start supporting the newer RCS texting commonplace in iOS 18, is the iPhone messaging taking part in area about to be leveled? Or are we simply exchanging one acronym for one more?
Confused? Don’t fear. We’re about to put out what may change with Apple’s adoption of the GSMA’s next-generation messaging protocol.
What’s SMS?
Quick Message Service (SMS) is likely one of the most ubiquitous messaging protocols on the planet. It dates again to the early days of cellular know-how. In December 1992, Neil Papworth, on the time an engineer at Vodafone, despatched the primary SMS textual content message when he wished his boss “Merry Christmas.” By the beginning of 2011, roughly 80 % of all cell phone customers globally — an estimated 3.5 billion folks — had been sending SMS messages each month.
Right now, nonetheless, the usual has some notable drawbacks. SMS messages are restricted to 160 characters, and texts you ship can’t embrace photographs, movies, audio or GIFs. For that, cell telephones have lengthy turned to a supporting protocol generally known as Multimedia Messaging Service (MMS), however it too has its share of technical limitations, together with woefully small message measurement limits. SMS additionally doesn’t help end-to-end encryption.
However for all of the methods SMS feels dated in an period dominated by prompt messaging platforms, it has one defining benefit: SMS messages are routed via your service’s cellular community, which means an information plan isn’t crucial to make use of the know-how. That truth has meant SMS has typically served as a fallback for extra superior protocols, together with Apple’s iMessage.
What’s RCS?
RCS is brief for Wealthy Communication Providers, although generally additionally it is marketed as “Superior Messaging.” Both approach, it’s typically positioned as a next-generation alternative for SMS and MMS. RCS permits customers to benefit from many options that had been beforehand unique to over-the-top messaging platforms like WhatsApp.
For example, the RCS Common Profile consists of full help for learn receipts and typing indicators. It may well additionally facilitate correct group chats, and permit customers to ship high-resolution pictures, video and audio clips. As of earlier this 12 months, Google’s implementation of RCS additionally provides by default end-to-end encryption (E2EE) for each one-on-one and group chats.
Not like SMS texts, RCS messages are routed over a cellular information connection or Wi-Fi hyperlink, with SMS functioning as a fallback. For that motive, the older protocol seemingly isn’t going anyplace anytime quickly.
One factor that’s necessary to recollect about RCS is that it’s not and has by no means been envisioned as a alternative or competitor to prompt messaging apps. At its coronary heart, RCS is a communication protocol between cellular phone carriers and between a cellphone and service. Profiting from RCS doesn’t require signing up for a brand new service. So long as your cellphone and service help RCS, and also you’re utilizing a suitable app akin to Messages by Google, you may benefit from every part the protocol has to supply — offered, in fact, the particular person or folks you’re messaging meet those self same necessities.
How does iMessage match into all this?
Apple introduced iMessage in June 2011, just a few brief months earlier than Steve Jobs died later that very same 12 months. Not like RCS, iMessage is a proprietary messaging protocol managed solely by Apple and out there (barring some occasional, unofficial workarounds) solely on iPhone, iPad, Apple Watch and Mac units. Beginning in 2024 with the iOS 18 replace, Apple plans to combine help for RCS in its Messages app. As of writing this text, the 2 protocols don’t talk with each other. As such, Apple’s Messages app will default to SMS/MMS when customers try and ship texts and media information to somebody with an Android cellphone.
From the attitude of an iMessage consumer, it may really feel like Android customers are caught in a bygone messaging period — though the latter isn’t at fault for the state of affairs. Because of iMessage’s reliance on SMS/MMS for Android communication, media information find yourself pixelated, there aren’t any learn receipts or typing indicators and neglect about making an attempt to contain a number of iPhone and Android customers in a single group chat.
How did we get right here?
Though work on RCS started earlier than Apple introduced iMessage, the protocol had one main drawback that doomed it to a gradual rollout. RCS is a multi-stakeholder challenge that features the involvement of the GSMA, a commerce physique that represents the pursuits of the cellular communications business at massive. In 2015, Google took a extra lively function within the proliferation of RCS when it acquired Jibe Cell. With Jibe’s know-how as a base, it’s successfully Google that gives the glue that binds the RCS ecosystem collectively, however for a very long time, the corporate did a poor job of aligning everybody concerned in RCS towards a shared aim.
In reality, the early days of RCS had been marked by false begins, with some carriers, together with a gaggle made up of AT&T, T-Cell and Verizon forming a short-lived three way partnership to push the protocol ahead earlier than ultimately aligning themselves with Google. Even Samsung did its personal factor for some time earlier than it too ultimately agreed to make Messages by Google the default messaging app it ships on telephones within the US.
For that motive, Apple has had little motive to undertake RCS. In any case, why wouldn’t it give a bumbling competitor a freebie? And as just lately as 2022, it appeared there was little to no likelihood the state of affairs was going to vary anytime quickly. “I do not hear our customers asking that we put a number of vitality into that,” Apple CEO Tim Cook dinner informed the Code Convention that 12 months when he was requested about RCS messaging. “Purchase your mother an iPhone” was his remaining phrase on the matter.
But it surely was additionally final 12 months that the European Union handed its landmark Digital Markets and Providers Act (DMA). The laws requires “gatekeepers” to not favor their very own techniques or restrict third events from interoperating inside them. Gatekeepers are any firm that meets particular monetary and utilization {qualifications}. Apple, in response to the regulation, is one such firm.
In the end, the EU dominated in 2024 that (although European regulators had loads of different directives for different points of Apple’s empire). Regardless of being in compliance, nonetheless, Apple had . Per famous Apple pundit John Gruber, Apple’s larger motivation might have been to . However regardless of the motive, it seems to be a executed deal: Apple reaffirmed RCS help is coming to the iPhone as a part of iOS 18.
Does Apple’s help of RCS imply the tip of inexperienced textual content bubbles on iPhone?
Alas, inexperienced bubbles are seemingly right here to remain. The corporate famous in its unique touch upon RCS that iMessage “will proceed to be the perfect and most safe messaging expertise for Apple customers.” That stated, even should you take that assertion to imply iMessage will proceed to show texts from non-Apple units in another way from these despatched from an iPhone, iPad or Mac, Apple’s adoption of RCS ought to result in a greater consumer expertise for each iOS and Android customers.
Once more, Apple wants to offer specifics, however it’s simple to examine a future the place its Messages app, because of RCS, correctly shows high-resolution pictures and movies despatched from Android telephones, and permits each iOS and Android customers to participate in group chats with out one thing breaking. Apple additionally stated in its unique November 2023 announcement it could work with GSMA members to enhance the prevailing Common Profile protocol, with a give attention to including end-to-end encryption to the usual.
After all, whether or not that interoperability ends the stigma round inexperienced bubbles is more durable to reply.
