The shutdown also affects Wingo customers

And I don’t understand that now, shouldn’t RCS replace SMS and SMS should be switched off like MMS at some point?

Why does this Swisscom page say that only Swisscom customers with Samsung could use Hadys RCS? RCS works on all Android phones?

RCS has so far been the prime example of a non-starter. As far as I can see, the new revisions of the standard still don’t support end-to-end encryption, right? Unfortunately, I still don’t see any chance of converting people from other messengers to this system. Support from Apple or Swisscom or not.

The problem is not that RCS cannot do E2E encryption, but that it is not allowed. RCS is offered natively by the network operators and is subject to various regulations, e.g. that monitoring must be possible. The problem is more the unequal treatment between app services and native Telco services.

Unfortunately, the Swisscom RCS environment was not stable with all the desired functional extensions. In addition, it is not connected to the rest of the RCS world and only Samsung has adopted the necessary settings so that customers can use RCS. Unfortunately, the collaboration with a giant of the Internet industry was suboptimal, so that two central elements were missing from the internal issues. Why could it come to this? I still ask myself that today.

I also see it like @PowerMac

RCS may be in the headlines again today, but tomorrow no one will be talking about it anymore. Sorry, but hardly anyone is likely to turn their backs on WhatsApp, Signal, Threema and Co. because of RCS. Apple can continue to support RCS for a long time. Main problem: Messenger services have become established among the masses. Even adults use WhatsApp today. In other words, it’s too late… The train has left.

Don’t the laws cited by @5018, which require network operators to monitor native messengers, and, for example, the GDPR, come from the same kitchen? Kind of paradoxical. But just…

It no longer matters to me whether I communicate virtually unencrypted via SMS or semi-simply encrypted via RCS. There are alternatives.

The subject of RCS has a solid background and is called the Digital Markets Act or DMA. In the future, WhatsApp will have to open. Apple is also “threatened”, especially the closed App Store or Apple Messages, which is why RCS is suddenly coming.

Once you are designated as a gatekeeper, the following requirements apply:

Thank you for all the answers😍

I think PTT’s answer is great

Swisscom apparently terminates a Samsung internal RCS.

It is advisable to install Google Messages on Samsung cell phones!

The original Samsung Message app already has the worm in it in terms of RCS.

I support several different Samsung phones if there are any questions.

From 2010 to 2019 I remained loyal to Samsung.

Unfortunately, Samsung has increasingly created a distance from me with its own app variants.

Since then I have been using pure Google Android phones until 2022 Gigaset and Fairphone4 for 15 months.

And yes, at the moment I find my Fairphone4 with a genuine leather case quite good in my hard and rough everyday work.

New Samsung phones also come with Google Messages preinstalled, but not as the default messaging app. Yes, Samsung offers various apps of its own and many functions that are not available on stock Android. That’s exactly what I like about the One UI interface. I can set it up the way I want. I also have a choice of apps. You don’t have to use the standard messaging app if you don’t want to. But in my opinion the topic of RCS is being exaggerated too much anyway. You might think that just because Apple said a word about RCS, they reinvented it.

I use RCS on my Androids (not Samsung) with no problems with the Google Messages app. In my case I see that encryption is activated. You can also display the key and check it with the “other side”.
The Swisscom article is confusing. I also called Swisscom and was confirmed that RCS would not be switched off.

In order for chatting via RCS to work between Android smartphones and, in the near future, also with iPhones, RCS in the “Universal Profile” (UP) version must be supported by the mobile phone provider (here: Swisscom) in the core network of the mobile phone network.

[https://www.heise.de/news/i-Messaging-per-RCS-Apple-ueberraschend-mit-an-Bord-9531264.html](https://www.heise.de/news/i- Messaging-via-RCS-Apple-surprisingly-on-board-9531264.html)

The GSMA industrial association is responsible for standardizing RCS in the “Universal Profile” form.

https://de.wikipedia.org/wiki/GSM_Association

Here is the read access to version 2.6 (December 19, 2022) of the RCS Universal Profile specification:

[https://www.gsma.com/newsroom/gsma\_resources/rcc-71-rcs-universal-profile-service-definition-document-v2-6/](https://www.gsma.com/newsroom /gsma_resources/rcc-71-rcs-universal-profile-service-definition-document-v2-6/)

In December 2023, chatting via RCS between an Android smartphone with the “Google Messages” app to an Android smartphone with the “Samsung Messages” app is NOT possible. Although according to the website:

[https://news.samsung.com/global/samsung-and-google-collaborate-on-rcs-messaging-for-android](https://news.samsung.com/global/samsung-and-google- collaborate-on-rcs-messaging-for-android)

[https://www.gsma.com/futurenetworks/digest/google-and-samsung-partner-to-accelerate-rcs-business-messaging-based-on-the-gsma-universal-profile/] (https://www.gsma.com/futurenetworks/digest/google-and-samsung-partner-to-accelerate-rcs-business-messaging-based-on-the-gsma-universal-profile/)

[https://www.gsma.com/newsroom/article/new-samsung-galaxy-s8-smartphone-pre-installs-rcs-messaging-based-gsma-universal-profile/](https://www.gsma .com/newsroom/article/new-samsung-galaxy-s8-smartphone-pre-installs-rcs-messaging-based-gsma-universal-profile/)

Both the Google Messages app and the Samsung Messages app support RCS Universal Profile.

The mobile operator Swisscom will therefore support NO RCS in the form of “Universal Profile” (UP) in the core network of the mobile network in 2023. Hopefully Swisscom will bring RCS Universal Profile support to their mobile network in 2024…

Technically speaking, with RCS Universal Profile the RCS client (Google Messages, Samsung Messages or Apple iMessage) registers in the core network of the mobile network. So that the IMS knows which mobile phone supports RCS and is “online”. This registration takes place in encrypted form using the SIP network protocol (SIPS -> SIP over TLS -> Server port: TCP 5061).

https://realtimecommunication.wordpress.com/2014/11/14/messaging-in-rcs/

The RCS client requests information from the IMS as to whether a conversation partner supports communication via RCS. And whether the conversation partner is “online” or “offline”.

The data transfer from RCS Universal Profile usually takes place as an “HTTP file transfer” in encrypted form (HTTPS -> server port: TCP 443) via the core network of the mobile network.

Thanks for all inputs. Fortunately, I don’t depend on the functioning of RCS for better or for worse. I’ll try it and see if it works.

Many providers are examining whether RCS should be reintroduced.
Is Swisscom also checking?
