Skinny's Siri Self Service
Pardon the rough edges! This is a quick-and-dirty export from Behance.
The content will get a proper rewrite soon. For now, it’s just migrated as-is.
Manage your plan, add-ons and keep track of your balance with your voice.

A Voice Interaction Design experiment
Based on Skinny’s Text Self Service and Siri Shortcuts, control all the important stuff about your Skinny account directly with Siri.
The end of each conversation results in Siri sending a text message in the background with the appropriate keywords, the user then gets an instant reply from Skinny.

This work has been made entirely with Apple Shortcuts and works out of the box with Siri on any iPhone with a Skinny SIM card. The next step would be to implement this feature in the Skinny app so Siri can also handle errors, have a richer UI and a more natural conversation.
