USSD are unrelated to SMS. Likely that you will not be able to dial USSD through SMS.
Since you mentioned about quota, would you consider downloading MyDigi app to check quota?

It is not available. To check the quota via that code, you need the 'dialler' app. But quota balance is already being displayed in the app or in the web version once you logged in.
