Samsung has released a new video in support of Google’s #GetTheMessage campaign which calls for Apple to adopt RCS or “Rich Communication Services,” the cross-platform protocol pitched as a successor to SMS that adopts many of the features found in modern messaging apps… like Apple’s own iMessage.
This sounds nice at a superficial level, but there’s a lot of reliability and backwards compatibility issues being ignored. During natural disasters and emergency situations, internet and cellular data are the first to fail. It’s not casual. For the phone and SMS (GSMA) protocols are sturdy enough that they can operate with very simple, low energy consuming and highly reliable machines. Internet data services on the other hand consume way more electricity (more expensive to have them operate with backup generators, for example) and are more delicate and prone to failure. They also need to be replaced more often. 100% of national emergencies systems run on phone and SMS tech, that could reliably operate for several decades with little maintenance that would cost billions to replace them with internet based system that were as reliable and durable. And then on top of it all, wired phones can even operate without electricity and connect with cellular terminals to contact other phones and cellphones. Only the tower needs to have power. There’s just a lot banked of that reliability that most modern conveniences don’t have.
In case of emergency it runs or it doesn’t run. No matter if cellular or data.
Best were something like Briar’s local wifi mesh standardized for emergency anyway.
Didn’t neblem suggest using SMS as a backup?
It doesn’t solve the problem of SMS being vulnerable to abuses, but it solves compatibility and security issues for the majority of uses. Besides, emergency alerts are pushed through IPAWS and typically don’t go over SMS at the carrier level.
I totally agree we can’t simply drop SMS immediately, but what am I missing in supporting backwards compatibility (for example via my pseudo number solution, like how VOIP works) preventing us from moving forward during a stagged shutdown in the span of decades? MMS and RCS both would also fail under cellular data loss, and SMS itself hasn’t always been available during major disasters. I’m not sure I buy the argument you can’t have similarly low energy towers (even with net neutrality states, you can still cap all bandwidth per user), and a simpler tower that only does data should be far more reliable than a tower that provides multiple carrier services given the simplicity (and it’s very rare to have towers that only do voice + SMS anymore).

Great points!
I don’t know for certain. But one point to consider is that you have to qualify your “simply” statements with the fact that we are talking about millions of towers and hundreds of millions of repeaters over millions of square miles. While RCS works on top of the backbone that’s already there and fallsback to SMS by design. So it might actually be simpler. The big up is that the server is on the carrier, not centralized, which makes it entirely different than what you are talking about and giving it more resilience.
There is so much nonsense being said about RCS, it will not fail under “cellular data loss”.
