# SIMCom SIM8262E-M2 The SIMCOM SIM8262E-M2 is a high-performance 5G module that supports both standalone (SA) and non-standalone (NSA) architectures, with fallback to 4G and 3G networks.\ Its wide frequency coverage and robust capabilities make it ideal for a variety of use cases, including private LTE and 5G networks, where reliable, high-speed connectivity is critical ![SIM8262E-M2](https://3922449203-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2FhI59CEwlyZWudTyz9EbD%2FSIMCOM%20SIM8262E-M2.png?alt=media\&token=d31c83b6-d407-4395-95b2-7aedb7e051c1) ### Quick Navigation * [Connect the SIMCom SIM8282E-M2 to Monogoto](#connect-the-lm960-to-monogoto) * [Network Configuration](#network-configuration) * [Network Activation](#network-activation) * [Useful Links](#useful-links) ### Prerequisites * Monogoto SIM * SIMCom LSIM8262E-M2 cellular modem * Access to a private network ## Connect the SIM8262E-M2 to Monogoto {% hint style="info" %} When connecting to the SIM8262E-M2 modem, keep the **AT Commands manual** next to you to look up details about commands. {% endhint %} {% file src="" %} **Connect to the modem**, enter the command: `AT` and wait for the response: `OK` **Reset the modem** to the factory 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 modem **hardware version**: ``` AT+CGMM ``` Request the modem **firmware version**: ```bash AT+CGMR ``` response: ``` +CGMR: 22131B08X62M44A-M2 ``` 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+ICCID ``` ### **Network mode preference**. **Manually set the preference mode**: * `AT+CNMP=71` → Enables 5G NR along with LTE, UMTS, and GSM (multi-mode operation). * `AT+CNMP=13` → Typically enables LTE/UMTS/GSM only (no 5G). To **test** if the network is set correctly enter: ``` AT+CNMP? ``` Expected response: `+CNMP:71` ### **IMS (IP Multimedia Subsystem)** **Manually set the IMS disable** ``` AT+CNV=0 ``` ### Network Configuration **Manually set the network**: Monogoto's private LTE network is indicated with the **MCCMNC** code: `99974`. To connect to the private LTE network, enter: ``` AT+COPS=1,2,"99974",11 ``` To **test** if the network is set correctly enter: ``` AT+COPS? ``` Expected response: +COPS: 0,0,"Monogoto5G 99974",11 `11` indicates that the modem is using 5G SA. **Check the radio signal strength and signal quality:** ```bash AT+CSQ ``` Example response: `+CSQ: 22,1` {% 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; a higher number indicates better signal strength. The second value represents the **signal quality** indicated by a value between 0 and 7, a lower value indicates better signal quality . 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` #### Request Serving Cell Information ``` AT+CPSI? ``` Example response: ``` +CPSI: NR5G_SA,Online,999-74,0x2,16385,5,NR5G_BAND78,638592,-780,-104,35 ``` * `99974` (the fourth value) indicates that the device being connected to Monogoto's Private LTE Network * `78` represents the cellular band the modem is currently using #### Validate if your device received an **IP address**: ```bash AT+CGPADDR ``` Expected response: `+CGPADDR: 1,10.XXX.XX.XXX` ### 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. 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. **Send 4 PINGs** to IP address `Google`: ``` at+cping="www.google.com",1,4,64,1000,10000,255 ``` Example response: ``` +CPING: 1,142.250.75.68,64,29,255 +CPING: 1,142.250.75.68,64,18,255 +CPING: 1,142.250.75.68,64,28,255 +CPING: 1,142.250.75.68,64,28,255 ``` {% hint style="success" %} Do you see an IP address? **Congratulations!** 🎉 **You’ve successfully connected the SIM8262E-M2 modem 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 * [SIM8262E-M2 AT Commands](https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2Fm5XnFM9DLsktLpDnsR1H%2FSIM82XX_SIM83XX%20Series_AT%20Command%20Manual_V1.03.pdf?alt=media\&token=abecb326-8fe2-4062-a3b9-2852b10ea47c) * [SIMCom product page](https://www.simcom.com/product/SIM8262X-M2.html) * [SIM8262E-M2 Hardware Design](https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2F8WE5U57bHSbBnD5ZSxCq%2FSIM826XX_SIM8X80-M2%20Series%20Hardware%20Design_V1.05_221020.pdf?alt=media\&token=2a44cde6-489e-4a7f-b350-83a6ff7dd070) * [SIM8262E-M2 Product Description](https://files.gitbook.com/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M0mPxGpottOEfcucXOR%2Fuploads%2Fv3WtDcfYts58i5gkSszo%2FSIM8262E-M2_SPEC_20220315.pdf?alt=media\&token=e9677b20-53d7-4db8-8bae-548ef607166f)
