Problems sending data from my XBEE to Device Cloud

I am using a 3G XBEE and am trying to send data to Device Cloud. I found the below link about how to write a micropython script to do this but, I am still not seeing anything. Also, when I do the script I am not getting the responses that it indicates even though I have followed all the instructions. Do I need to get a paid account or something to do this? Is there a document that walks you though this entire process? Can what I want to do be done without the python script?

thanks for any help you can offer.
