Why RCS Doesn’t Really Fix iMessage’s SMS Problem

Following

This has been a huge week for iMessage—in a very strange way; has this latest news finally given Apple’s iPhone users a reason to quit the green-bubbles/blue-bubbles and head elsewhere...

Updated 3/17; originally published 3/15.

Apple’s blue/green-bubbled messaging platform is back in the spotlight this week, with two separate news stories, both of which materially impact iMessage while totally ignoring it. Neat trick.

First, WhatsApp added to the media furore around its imminent third-party chats with a warning that it can’t extend its full security promise to include this new hub feature, that without control of the clients or endpoints at each side of a chat, it can’t be sure content is fully secure.

How does this impact iMessage? Well, iMessage has the same ruthless focus on security as WhatsApp—just look at its post-quantum crypto update last month. But if WhatsApp cannot assure messages outside its walled garden where transmission is end-to-end encrypted if not the endpoints, then it’s a stark reminder as to just how insecure iMessage is once users message outside the Apple bubble, because here not even transmission is fully encrypted, never mind those endpoints.

There was a fix for this late last year, kind of. Beeper Mini—remember that—turned up to fudge a bridge between iMessage and Android, suddenly end-to-end encrypted blue bubbles appeared on Samsungs. But Apple shut it down for lots of Apple-like reasons and it was soon no more.

Which brings us to the second piece of news this week—Beeper is back, kind of. “It’s the day all you Beeper Android fans have been waiting for,” the developer announced in an email. “Our new app is ready for you to try out!” It’s a complete, bottom-up rewrite they assured, “fast, clean and beautiful.”

Beeper made its name with its iMessage bridge. But this time it’s different—you’ve guessed it, no iMessage. As Android Police explained, “the days of trying to make iMessage on Android work are in the rearview mirror, and frankly, I think users are better off thinking of Beeper as a unified inbox for everything outside of the world of blue bubbles.”

That means Signal, WhatsApp, Telegram and Google Messages (RCS-enabled) all in once place, along with a bunch of other options. Ironically this makes Beeper more the kind of hub users might have expected from DMA’s mandated changes than the watered down offering they’ll actually get. It’s still unclear who’ll play in WhatsApp’s hub, but it’s unlikely to be the likes of Signal or Telegram or Google Messages. If you want to check one place for everything—this is it, kind of.

But no iMessage—and unless Apple does an Apple-like u-turn (think CSAM scanning or RCS), or regulators decide to flex their muscles, that’s unlikely to change. But RCS is coming soon. Raw and not end-to-end encrypted, but if you like one-tap responses, IP media sharing and typing indicators, you’ll be in luck come the fall and the burgeoning promises of iOS 18.

But if you want fully secured iPhone to Android messaging, then not so much.

Right now the only way to message iPhone to Android with the inbuilt platforms is to revert to SMS, a 1990s technology that has more holes than its old message character limit. RCS is a step up, but not enough of a step up. It’s like reverting to Google Messages before it shifted to default encryption and joined the top-tier Signal, WhatsApp and—yes—iMessage club. Even Facebook Messenger has now (finally) shifted to full encryption by default, which shows just how poor the alternative must be.

And so, continue using iMessage for your Apple friends and family—which means everyone in a group needs to be blue-bubbled. In the US, that might mean everyone you know—but not so much further afield. For those of us not in the US, the answer is an over-the-top platform. The best of the bunch being Signal and WhatsApp—with the latter now on pretty much every phone on every network, including—increasingly—in the US, where it has been downloaded hundreds if not thousands of times even since you started reading this article.

Don’t stop using iMessage, but do stop sending SMS texts from iMessage. Which means stop using iMessage outside Apple’s walled garden. And probably don’t use RCS either when it comes, not unless and until it finds a way to deliver cross-platform end-to-end encryption with Google. It’s a backward step from full encryption, as WhatsApp’s warning should have made abundantly clear.

The benefits in taking this approach are plentiful. You can securely message anyone, anywhere. You can use fully encrypted voice and video calls, cross-platform, with just a click. And—with Signal for now and WhatsApp soon—you can even hide your phone number and rely on a user name instead.

SMS is a terrible technology—you should avoid it at all costs. You have options and I recommend you take them. iMessage is an outstanding platform, with one of the best security architectures, including fully encrypted archives and backups with iCloud’s Advanced Data Protection. But when it comes to cross-platform messaging, it’s a totally different story. And it’s not about to change. Unfortunately...

3/17 update: Clearly if you should not use Apple’s iMessage to send SMS texts, then you shouldn’t use Google’s Messages app to do so either. This is a much bigger issue for Google than it is for Apple, because iMessage is sticker than its Android rival.

But Google is on a roll to make Messages more like iMessage—which no easy feat. It has just “stolen” one of Apple’s key iMessage features, as reported by Tom’s Guide. “Google’s been pretty active in updating the Google Messages app so that it functions and feels more like iMessage. In fact, it just ripped one of the best iMessage features—and there’s nothing wrong with that. Similar to how you can add an emoji effect animation in iMessage by long pressing a message and then selecting your reaction, Google Messages can now do the same thing.”

To be fair to Google, its stock Messages app has already progressed hugely in the last 18-24 months, with Google taking responsibility for the global RCS rollout and then enabling it by default. And more recently doing the same for full encryption. It also pushed and teased Apple publicly over its reluctance to adopt RCS, which it rightly said was holding back cross-platform messaging. Apple backtracked—to an extent, albeit the security caveats mean this issue is not yet resolved.

Google’s issue isn’t iMessage, though, it’s WhatsApp, which dominates on Android much more than on iPhone, especially given Apple’s US market lead. And WhatsApp has just blocked profile photo screenshots as its latest of many privacy innovations.

“I use an Android,” WhatsApp CEO Will Cathcart said back in 2021, specifically because his user base is “very Android heavy... I really want to actually use the product in the way most people are using it, so I use an Android... You look at a place like the US, most people have an iPhone, and the messaging experience works better on iMessage if everyone else has an iPhone.”

Back during its campaign to push Apple to RCS, Google blogged that “after three decades of SMS, here are three reasons to switch to RCS.” And the first of those three reason-—you guessed it: “security is front and center.”

The issue for both Google Messages and iMessage was clearly spelled out in that blog, long before Apple’s caveated RCS backtrack was anywhere close to fruition. “RCS enables end-to-end encryption, while SMS does not. This means that all one-on-one texts sent using Messages by Google, for example, are encrypted, so they’re private and safe and can only be seen by the sender and the recipient. And now, end-to-end encryption is starting to roll out for group chats.” Google’s final point is the clincher, though: “This shouldn’t even be a thought—just an expectation and something anyone texting should not have to worry about.”

And that’s the challenge now as Google—and Apple— try to push users to their watered-down cross-platform messaging, making the case that it’s ok to ignore the non-encryption when messaging outside the walled gardens. It doesn’t make sense, which is why RCS is an improvement—but not enough of an improvement.

And so when RCS does hit iOS in the fall, without the full encryption that WhatsApp and others have deployed for many years, the impact on RCS take-up versus WhatsApp will fall harder on Google than Apple. Google’s cosmetic feature updates such as the new emoji animations do nothing to resolve the gaping cross-platform security hole—and that remains the real issue with no fix currently in sight.
