I think I will go with the 2G network for my project. I am not having much luck finding a source for the SIM800H. Adafruit has them but on a different board. I ran all the numbers on the attached photo thru Dr Google without much luck.
Can you provide me with appropriate links to purchase this and the other bits and pieces I would need to get my EC stations on the air. Also looking for the weather proof box with the clear lid for another project.
