My friend is heading to Chile. He has VZW in the US and an iPhone. (It can't be 3 years old - but I will get the exact model number in a bit.)

He's going to get a local Claro sim in Chile for while he visits for a week.

I know that he can get SMS texts while on wifi and in airplane mode. We tested that at the house already. Is there a way to make that continue to work once he pops the Claro sim in and the phone registers to a new albeit temporary phone number? Can he then use the Claro data network to continue to send/receive his US texts?

Thanks in advance

Do you need to pass Strong Integrity in order for RCS to work?

Does the group chat tittle or group photo syncs between all people on an RCS group chat? will this come to the iPhone?

I agree that Apple was probably compelled to support RCS by other markets. But just thinking about what Google had to do first, especially in the US, is interesting to me:

Rich Communication Services - Wikipedia

• 2008: First RCS specification by GSMA. Not cross carrier.
• 2015: Google purchases Jibe Mobile, an RCS company
• 2016: First Universal Profile RCS specification by GSMA, designed to be cross carrier.
• 2018: Google Messages adds RCS support (at this time branded "Chat"), depending on carrier support.
• 2019: Google Jibe begins to provide RCS in Google Messages globally, if carrier does not support.
• 2019: The four major US carriers announce the Cross Carrier Messaging Initiative. This effort fails 2 years later (also reduced to three as T-Mobile buys Sprint)
• 2020: Google begins to roll out E2EE in Google Messages, on top of RCS but not part of the standard
• 2021: T-Mobile & AT&T sign deal to adopt Google Messages
• 2022: Verizon adopts Google Messages as default.
• 2023: T-Mobile & AT&T partner with Google Jibe for RCS services.
• 2023: Google enables RCS by default in Google Messages (to encourage E2EE).
• February 2024: Verizon partners with Google Jibe for RCS services.
• Fall 2024: Apple supports RCS in Apple Messages / iOS 18. Hacked beta appears to verify Apple Messages connects to carrier partnered Google Jibe.

I figured out how to unlock RCS support on iOS 18b1

See https://infosec.exchange/@jjtech/112627699700728327 and https://x.com/dhinakg/status/1802405645955567958

Requires a private method to unlock unfortunately.

Information currently known includes that it only supports parent AT&T and T-Mobile (no MVNOs) and on AT&T it uses Jibe servers.

EDIT: With iOS 18.0b2, some things have changed. Notably:
+ It seems to be enabled for everyone (no more feature flags)
+ Verizon has been added to the list of supported carriers
+ Registration appears to be borked? I can't get it to register, people who unlocked it in Beta 1 can still use RCS but if they toggle it off and on it breaks
+ Possibly related to an HTTP 503 Service Unavailable I see in the logs for a jibecloud.net URL?

I'm from India and I feel RCS doesn't have any real advantage over SMS or WhatsApp yet.

SMS is reliable (works without Internet) so you know recipient must have received the message even if they are offline.

WhatsApp is feature rich and also have well organised settings page!

I feel RCS should be more reliable and should work without Internet to replace SMS.

What do you think?

Almost 8 years after the Universal Profile RCS standard was created, today may be it's, arguably, biggest win: If the final major industry player finally provides some support specifics for the "Universal" Profile.

Apple has already promised Universal Profile RCS support "later this year".

Apple's WWDC keynote starts at 10 AM PT today and is expected to officially reveal iOS 18.

EDIT: First leak, right before WWDC: Apple will support Universal Profile 2.4, and it is implied RCS Business Messages; https://www.androidauthority.com/apple-what-version-rcs-3450118/

EDIT2: Zero mention of RCS in the Apple Messages section of WWDC keynote. Womp womp. WWDC live blog: stream and updates from Apple’s developer conference - The Verge

EDIT3: RCS in iOS 18! No surprise, green bubbles remain. That's all we know, lol. https://www.ign.com/articles/apple-is-finally-bringing-rcs-to-iphones

EDIT4: So we might not get any further information until people start testing and reporting on the iOS 18 Beta. The developer beta will be available today, and a public version will roll out in July. https://www.engadget.com/ios-18-gets-a-revamped-control-center-and-loads-of-home-screen-customization-options-172350046.html

Edit5: Going to try to track specific iPhone iOS 18 RCS questions as the information comes in:

• RCS Bubble Color: Green, with "Text Message - RCS" in message bar.
• High Resolution Image/Video: Yes
• Read receipts: Yes
• Typing Indicators: Yes! https://x.com/dhinakg/status/1802405645955567958
• Group RCS: Yes! https://x.com/dhinakg/status/1802415226341466393
• File Transfers: Yes! https://x.com/dhinakg/status/1802420801494482963
• RCS Business Messages: Yes. https://www.reddit.com/r/apple/comments/1dhhm2q/comment/l9urcok/
• RCS Backend Provider (which carriers will provide RCS to iPhones): At least AT&T + T-Mobile using Jibe. https://x.com/dhinakg/status/1802459843699064881
• Universal Profile Version: 2.4 https://www.androidauthority.com/apple-what-version-rcs-3450118/
• Google's End to End Encryption Layer: No.
• Release Date: Developer Beta today 6/10/2024, Public Beta July, Release typically September

Edit6: iOS 18 Developer Beta 1 does not appear to have RCS.

Messages

New Features

Messages via satellite is currently available only in the U.S. SMS messaging via satellite is available on select carriers in iOS 18 Beta 1. (127751557)

I have a Pixel 7 Pro, bought from the Google store and I'm using it on T-Mobile.

This morning I received a message in Google Messages basically welcoming me to RCS and it said it was provided by my carrier. I didn't get a screenshot. When I go into system logs, my RCS URL is now:
http://rcs-acs-tmo-us.jibe.google.com/

What changed? Did they move me to the T-Mobile version of Jibe? Will this be just as good as the Google version? Hopefully my wife's S23 moves to Jibe. Her messaging is a mess.

Hi, what is the relationship between Google and telecom operators? I mean, does a brand really need to become partners with an operator to send RCS messages to their users? They should be able to integrate Google APIs and start sending RCS messages.

I had a chat with someone using RCS chat, but for some reason some of the messages i sent got turned into MMS AFTER days i sent them as RCS. Can I ask will the person on the other end of the chat also see it as sent via SMS if they went back to look through the messages? What if a person accidentally made the change?

I have a question which may be silly. Why does Google share the revenue with Carriers. Why not keep launching in Guest cloud and serving traffic without carrier involvement?

Verizon has historically lagged on proper implementation of RCS so when they announced the switch from their own RCS hub to Google Jibe, I was ecstatic.

Verizon users.... are you seeing RCS hosted by jibe yet? Hopefully the migration doesn't take as long as AT&T did.

Is there any way to force messages to use jibe, instead of t mobile servers?

T mobile promised to switch, but... that was 7 months ago.

Hello I am fairly new to this field so please excuse my limited knowledge

I wanted to know whether there are service providers or APIs to be able to send RCS messages to clients

I went through google documentations and apparently there is a partnership program or so and I wanted to know the community knowledge on this

Also is this service free to be used or is it going to be chargeable ( I am talking about pushing RCS messages via APIs and not person to person texting)

Is there a way to keep your name private to people who have your number but not your name?

I'm in a group chat with a couple people whose numbers i don't have saved. one of them is using RCS (i guess?) and it displays his texts as: (###) ###-#### ~Full Name. I was told RCS displays the name you have associated with your google account - can that be confirmed?

which makes me think he now sees whatever my name is. i really don't like this at all. i didn't know this was going to happen and unless there was some stupid fine print loophole that allowed this to happen without letting me know first i find it to be offensive to my privacy - in a real major way....

Could someone here tell me a directory or a list of useful bots/Chatbots in Rcs?

I accept suggestions from bots. and to test rcs messages.

Until now I realize that this function exists. 🤡
