- completionHandler:
A closure the framework calls with the retrieved token and any error that occurs.

Your app has 30 seconds to call this method after the system generates the token before the system invalidates it. The framework maps the token to the ICCID associated with the original MFMessageComposeViewController instance used for UPI device validation.
