SIM7600G-H and UNO R3

Hello,

I would really appreciate your help getting a project going.

I am trying to use an Arduino UNO R3 board in conjunction with an SIM7600G-H to communicate with a cell phone. I am having a difficult time getting the SIM7600G-H to work with the UNO R3. I've seen a few resources that are using jumper cables to connect the UNO to the SIM7600G-H. Would it be possible to use it as a shield and directly place it on top of the UNO R3?

Another thing my group is running into an issue with is the power supply. We are a bit confused as to whether the USB connected to the Ardiuno would be enough to power the boards?

Lastly can you suggest some code to use for just testing whether or not the SIM7600G-H can communicate with the UNO R3?

Thank you for your help!
