For years, the iPhone’s two-tiered texting system has been a scorching matter. 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 gadgets 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 discipline 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 without doubt one of the most ubiquitous messaging protocols on the planet. It dates again to the early days of cell expertise. In December 1992, Neil Papworth, on the time an engineer at Vodafone, sent the first SMS text message when he wished his boss “Merry Christmas.” By the beginning of 2011, roughly 80 p.c of all cell phone customers globally — an estimated 3.5 billion individuals — have been sending SMS messages each month.
At this time, nevertheless, the usual has some notable drawbacks. SMS messages are restricted to 160 characters, and texts you ship can’t embody pictures, movies, audio or GIFs. For that, cell telephones have lengthy turned to a supporting protocol referred to as Multimedia Messaging Service (MMS), but it surely too has its share of technical limitations, together with woefully small message dimension limits. SMS additionally doesn’t assist end-to-end encryption.
However for all of the methods SMS feels dated in an period dominated by immediate messaging platforms, it has one defining benefit: SMS messages are routed by means of your service’s cell community, that means an information plan isn’t obligatory to make use of the expertise. That truth has meant SMS has usually served as a fallback for extra superior protocols, together with Apple’s iMessage.
What’s RCS?
RCS is brief for Wealthy Communication Providers, although typically additionally it is marketed as “Superior Messaging.” Both approach, it’s usually positioned as a next-generation alternative for SMS and MMS. RCS permits customers to reap the benefits of many options that have been beforehand unique to over-the-top messaging platforms like WhatsApp.
As an example, the RCS Common Profile consists of full assist for learn receipts and typing indicators. It might additionally facilitate correct group chats, and permit customers to ship high-resolution photos, video and audio clips. As of earlier this 12 months, Google’s implementation of RCS additionally presents 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 cell information connection or Wi-Fi hyperlink, with SMS functioning as a fallback. For that cause, the older protocol seemingly isn’t going anyplace anytime quickly.
One factor that’s essential to recollect about RCS is that it’s not and has by no means been envisioned as a alternative or competitor to immediate messaging apps. At its coronary heart, RCS is a communication protocol between cell phone carriers and between a telephone and service. Making the most of RCS doesn’t require signing up for a brand new service. So long as your telephone and service assist RCS, and also you’re utilizing a suitable app reminiscent of Messages by Google, you possibly can reap the benefits of the whole lot the protocol has to supply — offered, in fact, the particular person or individuals you’re messaging meet those self same necessities.
How does iMessage match into all this?
Apple introduced iMessage in June 2011, a number of 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 accessible (barring some occasional, unofficial workarounds) solely on iPhone, iPad, Apple Watch and Mac gadgets. Beginning in 2024 with the iOS 18 update, Apple plans to combine assist 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 recordsdata to somebody with an Android telephone.
From the angle of an iMessage person, it might probably really feel like Android customers are caught in a bygone messaging period — although the latter will not be at fault for the scenario. On account of iMessage’s reliance on SMS/MMS for Android communication, media recordsdata find yourself pixelated, there aren’t any learn receipts or typing indicators and neglect about attempting 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 undertaking that features the involvement of the GSMA, a commerce physique that represents the pursuits of the cell communications business at massive. In 2015, Google took a extra energetic function within the proliferation of RCS when it acquired Jibe Mobile. With Jibe’s expertise 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 truth, the early days of RCS have been marked by false begins, with some carriers, together with a bunch made up of AT&T, T-Mobile and Verizon forming a short-lived joint venture 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 cause, Apple has had little cause to undertake RCS. In spite of everything, why would it not give a bumbling competitor a freebie? And as not too long ago as 2022, it appeared there was little to no probability the scenario was going to alter anytime quickly. “I do not hear our customers asking that we put a number of power into that,” Apple CEO Tim Cook dinner instructed the Code Convention that 12 months when he was requested about RCS messaging. “Buy your mom an iPhone” was his closing phrase on the matter.
However it was additionally final 12 months that the European Union handed its landmark Digital Markets and Services 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 elements of Apple’s empire). Regardless of being in compliance, nevertheless, Apple had . Per famous Apple pundit John Gruber, Apple’s greater motivation could have been to . However regardless of the cause, it seems to be a finished deal: Apple reaffirmed RCS assist is coming to the iPhone as a part of iOS 18.
Does Apple’s assist of RCS imply the top of inexperienced textual content bubbles on iPhone?
Alas, inexperienced bubbles are likely here to stay. The corporate famous in its unique touch upon RCS that iMessage “will proceed to be the most effective and most safe messaging expertise for Apple customers.” That mentioned, even should you take that assertion to imply iMessage will proceed to show texts from non-Apple gadgets in a different way from these despatched from an iPhone, iPad or Mac, Apple’s adoption of RCS ought to result in a greater person expertise for each iOS and Android customers.
Once more, Apple wants to supply specifics, but it surely’s straightforward to check a future the place its Messages app, because of RCS, correctly shows high-resolution photos 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 mentioned in its unique November 2023 announcement it will work with GSMA members to enhance the prevailing Common Profile protocol, with a deal with including end-to-end encryption to the usual.
After all, whether or not that interoperability ends the stigma round inexperienced bubbles is tougher to reply.
