That same thing actually happened to me and couldn't reset it for whatever reason. I did find info that after 8 days(I think that is what it was) it should automatically reset. I did not wait because I being impatient and changed my number and it worked right away. So if you are attached to your phone number be patient and see if it works around the 8th day..
Just wanted to give an update that the 8 days thing seemed to work. Waited and keep chat settings off for 8 days until today, when I turned it back on it immediately connected and RCS is back again.

The conventional method doesnt work on Android 11. First Post is updated, you can find the instructions for Android 11 at the bottom of the first post
1. Install Alliance Shield X >> Create account and Give necessary permissions.
2. Look at this post and follow

Let me know if it works

I had Snapdragon N20U where RCS was working fine. I sold it and bought Exynos version, enabled RCS using Alliance shield and it shows up in menu but it still shows sms only when I write to contacts who I'm sure they use RCS

Hi everyone.

I'm using vodafone on my Note8 (android9). RCS works on google messages but I can't make it work on Samsung messages - even after toggling RCS on and off via IMS, restarting phone and force stopping messages. Is this limited to android 10/One UI 2.0 and above only? Thanks

I dont have an active sim in my note 8, i can check that for you over the weekend. Ideally it should work, i used to have RCS on my samsung messages on Note 8 but it was limited to other Samsung users. Never got around to digging deeper. I have a Tmobile note 8. Here is what t-mobile says about RCS https://www.t-mobile.com/support/de...note8/advanced-messaging-samsung-galaxy-note8
Please check with vodafone if they are supporting RCS from carrier side. RCS on google messages is Carrier agnostic and is using jibe.

I lost RCS before 3.1, it was working fine with 2.5 and fairly sure it worked with 3.0 for a while, then one day I couldn't send texts unless I turned it off, now it just refuses to enable at all even with Google messages and Alliance X tricks

Works good if I'm sending 1v1 rcs or text messages. But group messages primarily MMS with non RCS users doesn't always send as MMS. Will sometime send to each individual. This only happens while I have the RCS toggled on. Leaving volte enabled has no effect.

Has anyone else noticed this?
This happens to me as well. Pretty frustrating. Anyone aware of a fix?
 
Its Does not Show IM Settting on my phone, after i install google phone.
Try 2 Phone Note 9 and S9+ still the same. those 2 phone is unlock Phone ( no effect to any carrier).
Maby the latest update from Samsung was block it.

    Quick Note before you start this - If you are on stable one UI 3.x / Android 11 or greater, see the bottom of the post to see the workaround. Thanks to @knuschit

    Introduction - If you have ever bought a device that comes locked with the carrier you will see there are some carrier baked features missing in unlocked devices. While putting in your sim will change CSC of your device you might still not get all the features. So far i fail to understand why would device makers and Carriers make it so difficult for users. I have scourged through so many forums and found info like these where a t-mobile rep responds saying there is no way those features can be added to non carrier branded device ( Either a blatant lie or the reps are ill informed or both).

    My Device - Unlocked SM-N986U1 with tmobile sim - CSC - TMB/TMB/XAA

    Problem Statement- I want Video calling over LTE and RCS features.

    Solution - Follow the steps carefully and also see the attached screenshots -
    There are other ways of doing this by creating shortcut to ims service settings but i am posting something that most users can easily do.

    Quick Pre-Check - Before starting if you have been using RCS on Google Messages you might want to de-register. Follow the process here: https://messages.google.com/disable-chat.
    You can always activate it in case you want to go back to RCS on google messages.
    This will only work if you are on Android 10, or the Beta version of Android 11. Samsung has blocked this on Stable Android 11.

    STEPS
    1. Download and install Phone app (By google)
    2. Open the phone App that you just downloaded and make it your default Phone app.
    3. Dial *#*#467#*#*
    4. You will see the settings as in my Screenshot 1
    5. Tap on IMS Service Switch (The first Option)
    In case you cant see the screenshot - Just tap on the first option IMS service Switch, Then make sure MMTEL Switch and RCS Switch is toggled on.
    If you see below RCS Switch there is a section titled MMTEL
    Sub-options of MMTEL are
    VoLTE
    VoLTE-Video
    VoLTE-Call-Composer
    SMS over IP
    Supplementary Services
    Called Dial Third Party Number
    JUST TURN ALL THESE TOGGLES ON

    6. See the Screenshot 2 and move all the switches to ON.
    7. Go back to main page and then go to RCS Configuration settings and make sure they are selected to be always on as in Screenshot 3.
    8. I changed back to default phone app after this.
    9. And done you should have the video calling over LTE to fellow T-Mobile users activated now.

    I have already made a few calls and tested it and can confirm that this works. This might work for Sprint too.


    NOTE THAT - Default video call on contacts is still duo. you have to make a regular voice call to a contact first then you will see the native video call icon.

    These settings wont stick after OS/Firmware update via Odin, OTA or Sideload and steps would need to be repeated.

    Edit Update -You can See all three screenshots together here.

    Let us know how it goes here and if you explored any more settings and i will update this post with due credit.


    WORKAROUND: SINCE THE ABOVE METHOD IS NOT WORKING ON ONE UI 3.X / Android 11
    The conventional method doesnt work on Android 11 so use the method below:
    1. Install Alliance Shield X >> Create account and Give necessary permissions
    2. Open Alliance Shield X settings and toggle New App Manager Layout On
    3. Look at this post and follow
    4. See the Screenshot 2 and move all the switches to ON.
    5. Go back to main page and then go to RCS Configuration settings and make sure they are selected to be always on as in Screenshot 3.

    I can confirm this works.


    ADDITIONAL CONFIRMED INFO FROM USERS / TROUBLESHOOTING

    Try the following step in case you had RCS activated on Google Messages and doing the above steps does not get you RCS in the Native SMS App. Thanks @Compusmurf
    Also, might add. IF you were previously using Google messages, then you do this, you probably will have to UNREGISTER from Google Messages for Samsung Messages to pick up RCS.....
    https://messages.google.com/disable-chat
    Confirmed to be working for ATT
    I have U1 on ATT prepaid so I don't have advanced messaging features, tried this method and now I do. Thanks

    It works for other phones too
    I just followed these steps this morning on an unlocked Samsung A51 and it has worked great!

    I only get unable to start activity. Unlocked on T-Mobile. On Sprint I had native RCS.
    Did you toggle the knox switch? Make sure your settling page of Alliance shield app looks like my screen shot and then when you open the IMS settings it will look like my other screen shot.. Then you have to go to activities tab and select the first from the list and pick open and now you will see the IMS settings.. Just toggle the RCs switches like instructed in first post.

    Guys I Figured It Out!

    They didn't remove the ability to access the IMS settings you see in Google Phone, they just changed how to access them. I used an application called Alliance Sheild X. But I'm sure you can use ANY app that can launch app activities.

    I don't feel like writing it all out so i made a quick video:

    After doing this, i have all my RCS abilities back to normal. I'm on a U1 Snapdragon running Stock ONE UI 3

    This is the kind of stuff that makes me regret buying a Samsung.
    Any luck yet with the shield x replacement?
    According to their discord, SAMSUNG issued them a new license, but haven't cleared their old one.
    That being said, all code to disable apps is being removed because THAT is what breaks the knox TOS.
    OK good news is, it (Alliance Shield X) just got updated on my phone and their Knox license is back and I can confirm that I was able to switch the IMS setting to On.
    @hayabusa1300cc it works now. Try.

    I agree. This Knox license requirement came with their android 11 upgrade earlier it wasn't needed. I don't understand why they f*** with customers for no good reason. We can still get these Video over LTE features and all by flashing U rom via Odin but why the hell should we do that when a few tweaks were letting us enjoy our unlocked phones with carrier features (Carrier which Weare using and paying to) why Samsung had to take it away. This carrier control is fuc**Ed up situation in America and this should go away.
    Agreed. There is no reason for a carrier to make decisions on what you can and cannot use I you bought an unlocked phone straight from Samsung. Like how is it fair That Verizon gets to tell me what I can and cannot use on my own phone that I bought straight from Samsung and not them. And screw Samsung for conforming to them.
