1. Get the User's Phone Number on Mobile Device
2. Create a SubscriberCheck using the SubscriberCheck API
3. Request the SubscriberCheck URL on the Mobile Device over Mobile Data
4. Mobile Device requests SubscriberCheck Result via the Application Server

Next, we set construct the body object setting the `phone_number` field to a helper function that helps transform phone numbers by appending the calling code, trimming white-space, handling copy-paste phone numbers etc.
