Not only ussd, you can make any call without going to dialer

install below library from nuget

Xam.Plugins.Messaging

add below line in Android project MainActivity's OnCreate method:


CrossMessaging.Current.Settings().Phone.AutoDial = true;  
add android.permission.CALL_PHONE to the manifest file.

make call as


var phoneDialer = CrossMessaging.Current.PhoneDialer;  
if (phoneDialer.CanMakePhoneCall)  
   phoneDialer.MakePhoneCall("#121*1#");
