I tried the following code and its working fine for android 10 and 11

make sure to implement all requirements as per this : http://android-developers.blogspot.com/2013/10/getting-your-sms-apps-ready-for-kitkat.html

and Put following in your Mainactivity class

public void perm2(){
        Context mContext3 = getApplicationContext();
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.P) {
            RoleManager roleManager = null;
            roleManager = mContext3.getSystemService(RoleManager.class);
            Intent roleRequestIntent = roleManager.createRequestRoleIntent(
                    RoleManager.ROLE_SMS);
            startActivityForResult(roleRequestIntent, MESSAGE_CODE);

        } else {
            Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
            intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,
                    mContext3.getPackageName());
            startActivityForResult(intent, MESSAGE_CODE);
        }

    }
