To download the latest version, visit the [**SIMCom website**](https://www.simcom.com/product/SIM7600X.html), scroll down to the section **File Download** and search for a file called: `SIM7500_SIM7600 Series_AT Command Manual`. {% endhint %} **Reset the modem** to its default configuration: ```bash AT+CFUN=1,1 ``` Set the error reporting to **verbose**, resulting in more descriptive error messages (optional): ```bash AT+CMEE=2 ``` Check if the SIM card is attached and is not locked with a PIN, expected response: `+CPIN: READY`: ```bash AT+CPIN? ``` {% hint style="warning" %} If you receive an error, the SIM may not be inserted properly or the SIM is protected with a PIN. By default, Monogoto SIMs are not PIN protected. {% endhint %} ### Query device information Request the **product type** number: ```bash ATI ``` Request the modem **hardware version**: ``` AT+CGMM ``` Request the modem **firmware version**: ```bash AT+CGMR ``` 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+CCID ``` ### 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:\ `0` indicates **GSM**\ `1` indicates **GSM Compact**\ `2` indicates **UTRAN**\ `7` indicates **EUTRAN** (LTE)\ `8` indicates **CDMA/HDR** #### 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: Example response: ``` +COPS: (1,"NL KPN","NL KPN","20408",0),(2,"NL KPN","NL KPN","20408",7),(1,"vodafone NL","voda NL","20404",7),(1,"T-Mobile NL","TMO NL","20416",7),(1,"T-Mobile NL","TMO NL","20416",0),(1,"vodafone NL","voda NL","20404",0),,(0,1,2,3,4),(0,1,2) ``` 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** ![](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FfH8DCNlIW5R2VRiHwMG5%2FThings.png?alt=media\&token=2a63b922-cb41-4271-803e-ba9eab36566d) and select a specific **Thing**. Scroll down to **Mobile Identities** to find your profile in the column **Network Provider Name**. ![](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FddQeceTZxjtQYFPAHe95%2Fimage.png?alt=media\&token=4a3f1cbf-3922-48f9-af5d-2e292bd76b72) {% 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 LTE. **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 %} ### Network Activation **Set the APN to** `data.mono`: ``` AT+CGDCONT=1,"IP","data.mono" ``` To **test** if the APN is set correctly, enter: ``` AT+CGDCONT? ``` Expected response: `+CGDCONT: 1,"IP","data.mono","0.0.0.0",0,0,0` **Activate the PDP (packet data protocol) context:** ``` AT+CGACT=1,1 ``` **Test** if the PDP context is activated: ``` AT+CGACT? ``` Expected response: `+CGACT: 1,1` **To test what cellular technology and what band the modem is using** request the UE (User Equipment) System Information: ``` AT+CPSI? ``` The first variable shows the cellular technology, `BANDX` specifies the band. \ Example response: ``` +CPSI: LTE,Online,425-01,0x4F57,5977615,8,EUTRAN-BAND7,3050,5,5,-200,-1070,-634,4 ``` #### 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 SIM7070G 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 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 ``` {% hint style="success" %} **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. {% endhint %} ## Useful Links * [SIMCom AT Commands](https://www.simcom.com/product/SIM7600X.html)\ \&#xNAN;*Scroll down to the section **File Download** to find the latest version named: `SIM7500_SIM7600 Series_AT Command Manual`* * [SIMCom SIM7600G-H product page](https://www.simcom.com/product/SIM7600G-H.html) * [SIMCom SIM7600X product page](https://www.simcom.com/product/SIM7600X.html)
