Bring Your Projects to Life with [Arduino IDE 2.3.6 Software](https://www.arduino.cc/en/software/)
{% endhint %}
Run the Arduino IDE 2.3.6 to open the Serial Monitor.
{% hint style="info" %}
Install the [Cellular library ](https://docs.arduino.cc/libraries/arduino_cellular/)toolkit with [Sketch ModemTerminal files](https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FHbjZZGe0NXzMfv7MEx9c%2FGSMSerialPassthrough.zip?alt=media\&token=205d9476-a6bc-4819-b467-9ffe1eca3533)

## Connect the Telit Cinterion TX62-W to Monogoto
Request the **product type, hardware** and **firmware** **version**:
```bash
ATI
```
Request the **IMSI** (International Mobile Subscriber Identity):
```
AT+CIMI
```
Request the **ICCID** (Integrated Circuit Card ID), which is the identification number of the SIM card
```bash
AT^SCID
```
### Network Configuration
It is possible to let the modem select the network automatically, or to manually define a network to connect with.
#### **Option 1: Automatic Network Selection**
To set the modem to **automatic network selection** enter the command:
```bash
AT+COPS=0
```
Check the **network and cellular technology the modem** is currently using:
```
AT+COPS?
```
Expected response: `+COPS: 0,0,"",X`. The last digit indicates the cellular technology:\
`7` indicates **Cat.M1**\
`9` indicates **Cat.NB1**
#### Option 2: Manual Network Selection
Start with searching for available networks:
```
AT+COPS=?
```
{% hint style="warning" %}
It may take several minutes before the modem responds.
{% endhint %}
The modem responds with the **names** and the **MCCMNC** codes of the available networks. It also shows the cellular technologies the networks support:
```
+COPS: (1,"vodafone NL","voda NL","20404",8),(1,"NL KPN","NL KPN","20408",0),(1,"vodafone NL","voda NL","20404",9),(1,"T-Mobile NL","TMO NL","20416",0),(1,"NL KPN","NL KPN","20408",8),(1,"vodafone NL","voda NL","20404",0),(1,"T-Mobile NL","TMO NL","20416",8),(1,"T-Mobile NL","TMO NL","20416",9),,(0,1,2,3,4),(0,1,2)
OK
```
To find which of the networks Monogoto has **roaming agreements** with, review the [**Coverage lists**](https://docs.monogoto.io/getting-started/global-public-coverage).
{% hint style="info" %}
To find the **profile** of your SIM, visit the [**Monogoto Console**](https://console.monogoto.io/), open the page **Things**  and select a specific **Thing**. Scroll down to **Mobile Identities** to find your profile in the column **Network Provider Name**.
{% endhint %}
Check the **network and cellular technology** the modem is currently using:
```
AT+COPS?
```
Expected response: `+COPS: 0,0,"",X`. The last digit indicates the cellular technology.
**Manually set the network and the cellular technology**:
```
AT+COPS=1,2,"XXXXX",7
```
Replace `XXXXX` with the **MCCMNC** code of your operator, for example`"20404"` for Vodafone NL. Use `7` for **Cat.M1**.
**Check the radio signal strength and signal quality:**
```bash
AT+CSQ
```
{% hint style="info" %}
`+CSQ` returns 2 values separated by a comma. The first value represents the **signal strength** and provides a value between 0 and 31; higher numbers indicate better signal strength. The second value represents the **signal quality** indicated by a value between 0 and 7. If `AT+CSQ` returns `99,99`, the signal is undetectable or unknown.
{% endhint %}
#### Query Network information
This command returns the Radio Access Technology (RAT), MCCMNC operator code, and LTE band currently in use.
```
AT^SMONI
```
Example response: `^SMONI: Cat.M1,9260,28,-,FDD,204,04,18BB,010A20C,330,42,-82,-13,NOCONN,3`
### Network Activation
**Set the APN to** `data.mono`:
```json
AT+CGDCONT=1,"IP","data.mono"
```
Validate if the **APN** is set correctly:
```
AT+CGDCONT?
```
Expected response: `+CGDCONT: 1,"IP","data.mono","0.0.0.0",0,0,0,0,0,0`
**Activate the PDP (packet data protocol) context**:
```
AT^SICA=1,1
```
**Test** if the PDP context is activated:
```
AT^SICA?
```
Expected response: `^SICA: 1,1`
#### Validate if your device received an **IP address**:
```bash
AT+CGPADDR
```
Expected response: `+CGPADDR: 1,XX.XXX.XX.XXX`
{% hint style="success" %}
Do you see an IP address? **Congratulations! You’ve successfully connected the Telit modem to Monogoto 🎉**
{% endhint %}
## 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.
{% hint style="warning" %}
When cellular modems are idle for a long period of time, cell towers might drop the data connection to save resources. Sending regular PINGs is a good method for testing the data connection, as well as for keeping the connection alive because the operator registers your device as being actively used.
{% endhint %}
**Send 2 PINGs** to IP address `8.8.8.8`:
```
AT^SISX="Ping",1,"8.8.8.8",2
```
Example response:
```
^SISX: "Ping",1,1,"8.8.8.8",186
^SISX: "Ping",1,1,"8.8.8.8",151
^SISX: "Ping",2,1,2,2,0,0
^SISX: "Ping",3,1,151,186,168
```
