In the name of Mobile number Verification the Jupiter Application Logs out multiple times and ask for SMS verification.
Is there any Option to login without sending message from Mobile method.
Why not companies directly go for OTP Based login rather than this pathetic sending SMS method.
@Vivek_Karnani Welcome to the community. 
I am not aware of any other way to login other than through the OTP verification.
Have you tried resetting the app? (Clear storage and cache)
If you have done that already and still the problem persists, you need to mail Jupiter support at support@jupiter.money.
Hope your problem gets sorted out soon.
