I have Samsung Galaxy A31 and also my carrier is Airtel for dual Sim.
1. In Samsung messages, I entered the mobile number to activate RCS but registration fail is shown.
2. I installed Google messages apps from play store and enabled RCS features but while enter the mobile number still didn't get OTP code and stuck at "setting up" and "trying to verify your number".
How to fix it? Why RCS is not working in Samsung messages apps? I used it long months back but now not working. I want to use RCS in Samsung messages
