Once you've enabled Amazon Calling using a telephone number that can receive texts your off to the races in using Amazon Calling on your Amazon Echo. This is a terribly powerful feature, that is totally free. It doesn't use your data or minutes on your cell phone.

Oh, I almost forgot, we'll discuss video conferencing as well.
