### Prerequisites
* Monogoto SIM
* [Waveshare SIM7600G-H](https://www.waveshare.com/sim7600g-h-4g-hat-b.htm)
* Raspberry Pi 2, 3, 4 or Zero
## Get Started with the Waveshare SIM7600G-H
Insert the **Monogoto SIM card** at the bottom of the Waveshare HAT.
{% hint style="info" %}
This guide explains how to connect the Waveshare HAT to the Raspberry Pit. It is also possible to **connect your Windows, MaxOS or Linux machine to the Waveshare HAT directly** allowing you to configure the SIM7600G-H modem without the need for a Raspberry Pi.
To do so, connect your computer to the micro USB port of the Waveshsare HAT and connect to the modem using PuTTY (Windows), minicom, screen or miniterm (Linux/MacOS). When using Windows, [**this driver**](https://www.waveshare.com/w/upload/1/12/SIM7600X-Driver.7z) is required.
{% endhint %}
Connect the **LTE** and **GNSS antennas** and add the Waveshare HAT to a Raspberry Pi. When using a Raspberry Pi Zero, the board should be connected right away with the help of the pogo pins. When using a Raspberry Pi 2, 3 or 4 you need to connect to the devices using a USB cable.
 
Power the Raspberry Pi and connect to it using SSH, or by connecting a keyboard and mouse.
The **PWR** LED of the Waveshare HAT lights up **green**, the **NET** LED starts blinking **red**.
Enable the **hardware serial**, allowing the Raspberry Pi to communicate with the Waveshare HAT. To do so, open the **Raspberry Pi Software Configuration Tool** by entering the following command in your terminal:
```bash
sudo raspi-config
```
Select: **3 Interface Options** > **P6 Serial Port**
 
Answer **\** to “Would you like a login shell to be accessible over serial?”
Answer **\** to “Would you like the serial port hardware to be enabled?”
 
Install **minicom** to be used as the tool to interface with the SIM7070G modem:
```bash
sudo apt-get install minicom
```
{% hint style="info" %}
Alternatives to **minicom** for Linux or MacOS are **miniterm** or **screen**, feel free to use your application of choice. When using Windows to connect to the Raspberry Pi, you can use **PuTTY**
{% endhint %}
**Connect with the modem** via port `ttyS0` using minicom:
```
minicom -D /dev/ttyS0
```
Enter `AT`, if the modem responds with `OK` you successfully connected to the SIM7070G modem.
{% hint style="warning" %}
In case you don’t manage to open the ttyS0 connection or don't receive an `OK`:
* Try rebooting the Raspberry Pi and try again
* Try connecting to the SIMCom modem using USB port: `ttyUSB2`
* Double check if the **NET** LED is blinking **red**. If not, the modem did not boot up
* Be patient, it may take some time before the modem responds
{% endhint %}
## Connect the SIM7600G-H to Monogoto
Visit the SIMCom SIM7600G-H documentation for a detailed guide on connecting the modem to Monogoto.

{% endcontent-ref %}
## Test the connection by sending a PING
A PING test can be performed to test if the modem has an active data connection with a mobile network.
**Send 5 PINGs** to IP address `8.8.8.8` with a timeout of 20 seconds.
```
AT+CPING="8.8.8.8",1,5,64,1000,20000,255
```
If the connection is active, you will see 5 PINGs with a number representing the response time in milliseconds. Example response:
```
+CPING: 1,8.8.8.8,64,104,255
+CPING: 1,8.8.8.8,64,93,255
+CPING: 1,8.8.8.8,64,145,255
+CPING: 1,8.8.8.8,64,75,255
+CPING: 1,8.8.8.8,64,157,255
```

**Great work on connecting the SIM7600G-H to Monogoto!** Have a look at the **Things** logs in the [**Monogoto Console**](https://console.monogoto.io/) to find more details about the established connection.
