Connection with serial module:
About the USB cable, you can make one as below
Note: you need install driver for serial module and need switch it to 3.3V    

You can use SSCOM or other serial port software
Choose COM port and set BaudRate to 115200
Send AT Command

SIM7000A/G is compatible with Arduino UNO.
First, you need set the baudrate to 9600

How to change the baud rate? Connect SIM7000A/G module with serial module (as the 1st picture showed)
Send AT Command AT+IPR=9600;&W

 When it shows OK, that means the BaudRate already set from 115200 to 9600
Just in case, you can choose BaudRate 9600 and send AT to test.

Connection with 5V MCU:
TXD to D0
V_MCU to 3V3 or 5V
RXD to T0
