Question RCS in Samsung Messages doesn't work on S21 Ultra Unlocked [T Mobile US] - Samsung Galaxy S21 Ultra

Hi All
I have T mobile US. I made a mistake by getting the S21 Ultra unlocked version from Samsung. Now RCS doesn't work on native Samsung Messages app and no I don't want to use google messages app. Is there a work around or Time line on when they will open RCS on Unlocked devices?
Thanks in advance.

Same issue here. I am using Google Messages for now.

Yeah I don't want to use Google Messanger.
Anyone know how long it will take for them to allow RCS on native Samsung messages app for S21 ultra Unlocked T mobile customers?

If it is in fact working on T-Mobile firmware, then flash the T-Mobile firmware.

IIRC (could be wrong) Samsung said that their Messaging app won't support RCS... But if that's the case, then you can blame Samsung for not including it at all lol. But back when I had a Note 20 Ultra, Samsung said the same thing, however, there was this quick little setup that let you use RCS with Samsung messages.
It started with the installation of Google Messages and activation of RCS. But I just can't remember the following steps... Just search for what I mentioned on XDA and you'll probably find the post. But either way, after testing it out and having it work, I switched back to Google Messages anyways as it had a much better interface and better features for a techy/nerdy person like myself =)

I do remember this when I used the process for my Note 10+. Unfortunately that process doesn't work for S21 anymore.

Yeah, thanks for the update. I just looked into it and the IMS command via Google Phone was removed in Android 11 - hence why this doesn't work anymore =(. What a let down.

I figured out that if you flash the U firmware on the U1 phone and use the HOME_CSC, it'll give you the updated Samsung Messages with chat settings.

Google Messages is getting a makeover on Samsung phones. Is your phone eligible?
The Google Message app is getting a One UI-inspired makeover on Samsung phones making one handed use easier.
www.androidauthority.com
It's part of their closer partnership with Google that spawned the Galaxy Watch4. They're basically slowly abandoning Samsung Messages (and probably the rest of their own stuff eventually) and working more closely with Google to make OneUI-matching versions of the Google app suite. Why spend time developing their own tools when Google will do the work for them, I guess.

You need to download the app Carrier Services and also Google Chat.
You're gonna have a prompt asking for your number on Messages.
Then you can Uninstall Google Chat.

Google Pay After Sideload?

I am reading conflicting information on this. Is there confirmation that Google Pay works with a sideloaded P40 Pro Plus?
Yes, I have it. No issues at all (although it took a wee while to sort out notifications for GMail but the Huawei Mail App sorted that!)
I can't add a card and it says it may be because the phone is rooted or altered.

Sorry can't help with that one, I haven't tried it. I did use Samsung Pay on my Note 10+ but haven't used Google Pay.

Question Google Messages

All,
I thought Samsung said at their unpacked event that they were moving to native Google messages. Mine looks like it is the Samsung messaging app Version 12.1.01.25. Anyone has any nsight on this? I have the s21 ultra 512GB directly from Samsung using T-mo.
A little research -- https://9to5google.com/2021/01/15/galaxy-s21-google-messages-pre-installed/
Not installed in the US... Why?
It was always only for non-US phones, US phones got stuck with Samsung Messages. We will have to wait for someone to upload the APK so that we can sideload it.
And for anyone wondering the Google Messages version in the Play Store is different and doesn't offer the integrated features that come with the Samsung version of it.
I wish they would stick to one of the two apps, not both. My 21 came with both preloaded and it's getting pretty ridiculous. There's pretty much double apps everywhere now, even a secondary keyboard by Microsoft! And I can't even uninstall them!
I am using the google messages for s20 ultra. I downloaded from the play store just fine
US S21 here. I downloaded from play store. It works but it says "chat features unavailable for this device"

That's on your carrier. RCS and chat features worked fine and activated immediately for me on T-Mobile.

yeah and nothing malfunctions, except I can’t get RCS to work.
EMEA Version came with Samsung Messages.
Installed Google Messages and have chat features in it.
Yeah, it's weird. Just got my s21. Text messages that are being reply to me were still going to my old phone that didn't even have a sim card. Searched and found that Chat features needed to be turned off on the old phone...didn't work either until I just uninstalled the app. Now chat features are not available on the s21. Says to call carrier. Figure it's a network issue holding onto my old device info and not releasing to my new? Maybe it just takes some time.
[Didn't know that Samsung is supposed to have a messaging app that integrated with googles.]

I have exactly the same problem, cannot activate the chat function because the validation SMS does not work either. If anyone finds the solution I am listening.

Thank you! How hard would it be for the Google Messages app to direct users to download the Carrier Service when they try to enable Chat features but are denied. Chat set up immediately after installing Carrier Service.
Edit: I'm on T-mobile with the T-mobile S21 Ultra.
I just removed google messaging app from mine, through ADB.
I was like.. what?? Why are there 2 apps with the same name "messages" in my drawer?
anyway, got rid of it
I have the Verizon version of the ultra and there were no issues with getting Google Messages to work with the chat features. All I did was download and install the app. I also made it my dark messaging app in Settings > Apps > Default apps.
I use T-mobile and and have the s21 ultra unlocked on Tmobile, and I use the google messages and chat features work perfectly fine.
On Tmobile 512 unlocked.
If I want RCS with call and text on other devices .(Play store version, of Google messages does not support Samsung text and call on other devices) I had to go on "U" firmware with TMO carrier services and stick with Samsung messages.
I tried installing Google " NATIVE"messaging for Samsung. That apk that was posted in another thread and it would not install.
Also it does not seem that continue app on other devices is working either .
My tab s7+ and S21 ULTRA are both on 3.1 and they have the options enabled ,but no
Worky.
Honestly I prefer the Samsung messages app because it gives an audible notification when you're on a phone call. The Google messages app doesn't. It sucks to be on a call and not know a text message came in. If Google messages would add that simple feature it would be just about perfect.
Question for those that have the Google Messages prebaked in, can one of you upload it for us to use? If I'm not mistaken that is the one that is specifically developed to be themed alongside One Ui. Thanks in advance!

Question Anyone pull the Custom Google Messages APK yet?

Now that the phone is officially out, has anyone outside the US pulled their Google Messages apk and uploaded it anywhere? Curious to see if we can get it working on the US variant.
What's different than the play store version?

It works with call/message continuity for people who have tablets (messages can normally only be forwarded if you use Samsung Messages). Might be some other cool stuff or differences too, but that's what I'm after.

Someone probably will need to repackage and sign it. Usually you can't just install a system app off of another device. I haven't been into Android modding/development for a few years, so hopefully someone can get that done now that we have this APK here.
If someone can get this working ,it would be great. I jumped to U TMO firmware to keep RCS and not lose text and phone on my TabS7+

We honestly might even need their Call & Text on Other Devices apk too. The current one we have tries to kick you off if another SMS app is installed.
I've tried to sign the app but, it still refuses to install. Let me know if any of you have any luck!
I don't have the watch or tablet so I don't need the continuity part. Annoyingly my s21 no longer has encrypted messages.

Is it not linked to the version in the Play Store for updates or beta sign up? Encryption was a beta feature.
It is still linked but whenever it updates it has a slightly different file name and no encryption. But the version number still matches the latest beta version. For now I uninstalled updates, sideloaded the regular version and disabled automatic updates.
Anyone manage to get this working yet?

I'd probably start a separate bounty thread for it. I don't want to make multiple threads on the same topic though myself, so I'll let someone else. It'll likely be a two part job though with both the Google Messages and Call & Text on Other Devices apps needing modifications.
Would also chip in if someone could get this working for us

Try using Total Commander app from Google store, I get most of 'other' apps installed with that app. The apk files must go to root Download folder so you can easily find it on Total Commander and install it after you grant permission for it. It works on non-rooted phones as well.

INSTALL_FAILED_VERIFICATION_FAILURE
Please select all split APK parts!
Are we missing more apk?
Does anyone have any screenshots of the actual app. Are there any visual differences in the one ui messages version?
Just an FYI for anyone hoping to use RCS on their tablet
I got the beta on my exynos s21u and while it does work with the call & text anywhere feature, it currently only replies as SMS even if the inbound msg is RCS
I'll also contribute some funds to get this working if need be. Sad my S21 snapdragon doesn't come with it already. Samsung really needs to polish their brand and stop making it so diverse between countries.

Question What SMS/text's application are you using?

As title, what aplication are you using for sms/text's?
Currently I am using stock samsung, but is is incredibly slow. I mean I type quickly, and sometimes my messages appear after 5-10 sec in it. Also I can get a text and when I enter apk I need to wait another 3/4 sec just to let it appear. Very frustrating, looking for something better, maybe google messages with one ui are better? Or maybe you got some alternatives?
I use the Google app. IDGAF about Samsung and their apps.

Samsung Messages before. Then started using Google Messages for RCS. Switched back to Samsung Messages as RCS is now supported by my Service Provider in Australia. IMO, Samsung Messages is better than Google's in the functionality wise.

Your Service provider has to support RCS to start with. I have Galaxy Watch. I get more options on my watch notification. Also, the notification tray has functionality to copy OTP or any numbers if the text has one.
I hate to sound thirsty, but look at my post regarding one ui themed Google messages .
I'm deep into my 2nd whiteclaw (mango) ,so I'm like super click bait right now
Been using google app, now switched to samsung messages. Only sms to mms conversion is annoying. Do you know how to turn off sms to mms conversion?

Question Uninstalled Samsung Messages via ADB. Please help me to add it back

I was removing extra bloat from my Samsung phone via ADB (uninstalling the stock Samsung Messages). Now, I would like to add the stock Samsung Messages app back. Could someone please tell me the easiest way to install the app back? I can't find it on the Samsung Galaxy store or Google Play store.
I tried downloading the latest APK. Unfortunately when I click on the APK via Samsung "My Files" (which already has the ability to install apps from unknown sources), the app looks like it's installing.. but then, it ultimately says "App not installed".
Maybe, there's a way to put it back via ADB? If so, can someone please tell me exactly how to do it? I don't even remember the exact commands I used to remove it in the first place.
try shell command:
cmd package install-existing com.samsung.android.messaging
Out of curiosity: why are you adding it back?

I was trying to enable the feature Make calls and send messages from your Galaxy tablet . It wasn't working... so, I incorrectly believed putting back the stock Samsung Messaging app would resolve the issue.. which it didn't. After reading that link more carefully, it clearly said this feature isn't compatible with Verizon carriers. Too bad. I'll probably just end up uninstalling the stock app again since it has no use to me. I like Google Messages.

I have the Tab S7 and the Call and Text on other devices feature is very handy. I love it.
But if your carrier has blocked the function for some reason, the same functionality (SMS alone, not calls) can be replicated with Google Messages once you link the two devices together.
