@bshankar I have a #KaiOS phone which doesn't support #RCS, and I thankfully don't receive much #spam on #SMS either, although many of my friends seem to get the same. (That's why many have stopped checking SMS unless they need an OTP or something)
Do you find RCS spam to be similar to SMS spam? Also, I'm guessing RCS supports rich content like images and stuff? So does the spam include that as well?
Some good and bad news on RCS' end-to-end encryption rollout:
"Also, because this is carrier dependent, I suspect the rollout of end-to-end encryption (for #RCS) will be a little rocky for a beat and, in some countries, never made available."
End-to-End Encryption for RCS, enabling Secure Cross-Platform Messaging.
Text messages sent between iOS & Android devices will soon benefit from end-to-end encryption, after the GSM Association published new specifications for the RCS protocol that include support for cross-platform E2EE.
![The new GSMA specifications for RCS include E2EE based on the Messaging Layer Security [MLS] protocol via what's called the Rich Communication Services [RCS] Universal Profile 3.0.
"The new specifications define how to apply MLS within the context of RCS," Tom Van Pelt, technical director of GSMA, said. "These procedures ensure that messages and other content such as files remain confidential and secure as they travel between clients."
<https://www.gsma.com/newsroom/article/rcs-encryption-a-leap-towards-secure-and-interoperable-messaging/>
This also means that RCS will be the first "large-scale messaging service" to have support for interoperable E2EE between different client implementations from different providers in the near future.
The development comes nearly six months after the GSMA said it was working towards implementing end-to-end encryption [E2EE] to secure messages sent between the Android and iOS ecosystems. The move followed Apple's decision to roll out support for RCS in its own Messages app with iOS 18.
Google said, "We've always been committed to providing a secure messaging experience, and Google Messages users have had end-to-end encrypted [E2EE] RCS messaging for years. We're excited to have this updated specification from GSMA and work as quickly as possible with the mobile ecosystem to implement and extend this important user protection to cross-platform RCS messaging."](https://nerdculture.de/system/media_attachments/files/114/194/978/375/605/770/original/ae19ccf056d1258e.jpeg "The new GSMA specifications for RCS include E2EE based on the Messaging Layer Security [MLS] protocol via what's called the Rich Communication Services [RCS] Universal Profile 3.0.

GSMA confirms end-to-end encryption (E2EE) for RCS, bringing much-needed security to cross-platform messages between Android & iOS! 
This means safer & confidential communication. Google is also working to implement & extend user protection to cross-platform RCS messaging.

The #RCS protocol https://en.wikipedia.org/wiki/Rich_Communication_Services is available (enabled?) on most #Android phones.
I see several problems (vs SMS) and would like informed people to correct me if needed
1. it needs data access to communicate, vs SMS which only needs mobile phone access
2. all messages pass by #Google servers
3. rooted android phones (like mine with @GrapheneOS ) can't use it (I don't want!)
Please continue using SMS and Signal!
Retoot and answers appreciated
Well resetting my phone fixed my #RCS issue
A friend: “Given telcos have been obliged to remove #encryption they put around services (to facilitate Lawful Intercept), given they supported LI of Skype breakout and given that the #GSMA sits on the 
#IPCO Tech board, I wonder what all that means for #RCS?” << Great questions!

»RCS – Ende-zu-Ende-Verschlüsselung zwischen iOS und Android:
Mit RCS Universal Profile 3.0 ist E2EE Teil des RCS-Standards. Ein wichtiger Schritt für die Sicherheit plattformübergreifender Nachrichten.«
Spannend und es nimmt mich wunder wie dies sich durchsetzt und es evt. über die Handys hinaus weiter allgemein, Anbieter unabhängig, genutzt werden kann.

@arstechnica@mastodon.social Carriers in italy don't even support #rcs :(
But will it be as secure as Signal?
