How do I setup Hosted Messaging and text enable external phone numbers?

Hosted Messaging is a service that allows Bandwidth customers to enable non-Bandwidth owned/operated phone numbers for messaging. This product is designed to allow customers to send and receive SMS/MMS messages using the Bandwidth platform while leaving the voice service in place with the current carrier/service provider.
