Amazon Two Way SMS

I am wondering if anyone knows how to set up two-way SMS communication with Amazon AWS PinPoint and SNS.

I am working on an application that we would like to enhance with the ability to communicate with our server via simple text messaging with our server.

The idea would be roughly this.

Server: "Text A for option A, Text B for option B"

User: "A"

Server: "Thank You, now, rate your experience from 1 to 10"

User: "6"

Server: (If answer is less than 8) "How can we make your experience better" (else answer is greater than 8) "Thank you for your feedback".

Twilio offers this service, and its pretty easy to use. I am evaluating our options and have a preference to go with AWS if we find out that it's something that works.

Thanks in advance for any help.
