Unable to register RCS.

[Suvadeep1982]

RCS was working fine but out of the blue it just turned off and won't register again at any cost. Once I click on the chat settings it shows a pop-up asking to register for chat service. After clicking start the chat settings gets greyed out for 2-3 minutes then shows registration failed.

Rebooted my device. Cleared cache and data of message app but not working. Device: Note 9.

Any help. Thanks.

It never worked for me ever specially on Jio. So I used Google messages and RCS works great and its much better than stock Samsung message app.

Press message app for 3 secs and go to app info. Go to storage and delete cache and data and try maybe it will work for you

I have deleted cache and data of message app and rcs settings for at least 15 times and still didn't work. Maybe Google message is the only option.

Yes try Google messages its good. Which sim provider you have. So far airtel and jio allow RCS I don't know about VI

Rcs will not work on dual sim if you're using dual sim it won't work properly , use single sim

[Suvadeep1982]

No it was working perfectly. But suddenly stopped working. One can only register one number per device for RCS if his/her device and service provider Support rcs even in dual sim device.
