Hi @Doan298282,

Thanks for the info. To help you out properly, could you describe exactly what’s happening when you try to connect to the internet?

For example:

  • Are you getting any error messages?
  • Is the SIM7600E being detected by the Raspberry Pi?
  • Have you run any AT commands or setup steps so far?
  • What makes you think the connection isn’t working — is it just no internet access, or does the module fail to initialise?

Let me know what you’ve tried and what you’re seeing, and we can go from there!

First, I don’t know well the process for connection with internet.
I tried to run AT commands. but seem to not assigned IP address.
Could you let me know why this error happened?

23

Is there anything that I can reference for internet connection?

HI @Doan298282,

Yes, there are some helpful guides you can follow to get the SIM7600E connected to the internet on a Raspberry Pi. Here are a couple of good starting points:

1. Waveshare Wiki (Official Guide)

Waveshare has a detailed setup guide for this module, including how to use PPP or the quectel-CM connection manager:
https://www.waveshare.com/wiki/SIM7600E-H_4G_HAT_for_Raspberry_Pi

Look for the “Getting Started” and “PPP” sections in particular. These walk through installing the required software and setting up a mobile data connection.

2. Core Electronics Tutorial

We also have a guide on using cellular modules with Raspberry Pi:

No worries at all, we’ll walk through it together step by step.

From what you’ve said, it sounds like the SIM7600E module is responding to AT commands, but it’s not getting an IP address, which usually means something in the setup isn’t quite finished yet.

To help figure it out, could you please try the following and let us know what happens?

Step 1: Confirm the SIM is working

In your AT command terminal, type:

AT+CPIN?

This should reply with:

+CPIN: READY

If it says something else (like SIM PIN required or not inserted), let us know.

Step 2: Check the signal strength

Type:

AT+CSQ

You’ll get a response like +CSQ: 15,99
The first number shows signal strength. Anything 10 or higher is usable.
If it’s below 10 or says 0, the module might not be picking up a mobile network.

Step 3: Check if it’s connected to the network

Type:

AT+COPS?

If the response shows a network name, that’s good.
If it’s empty or has an error, then it’s not registered.

Step 4: Try setting the APN

The module needs to know your SIM card provider’s APN. For Lycamobile, it’s usually:

AT+CGDCONT=1,"IP","data.lycamobile.com"

If you’re in a different country, the APN might be different — let us know and we’ll check it for you.

Once you’ve run these commands, let us know:

  • What response you got for each step
  • If anything showed an error or looked unusual

That will help us figure out exactly where the issue is and what to do next. You’re doing well so far.

It is saying that It does not support LTE/4G now. Right?
I think it should be like the following.
+GCAP: +CGSM, +DS, +ES

Hi @Doan298282,

Thanks for sharing those screenshots, they’re super helpful.

Here’s what might be going on:

  1. Module is in GSM-only mode
    The SIM7600E supports LTE, but it may be locked to GSM. Let’s try unlocking it.
  2. Network coverage issue
    Lycamobile might only be offering 2G in your area. You could try a different SIM (like Telstra or Optus) to test.

Try this command to enable all radio access technologies:

AT+CNMP=2

This tells the module to automatically choose between GSM/UMTS/LTE.

Then reboot the module or restart the Raspberry Pi, and check again with:

AT+CPSI?

If it still only shows GSM, try this command to check what networks are available:

AT+COPS=?

(Be patient — it can take a couple of minutes.)

Let us know what that returns, and we can guide you from there.

Thank you.
I tried the above process, but I got the same results.

Thanks for trying those steps and letting us know.

Since you’re still seeing the module stuck in GSM-only mode (+GCAP: +CGSM,+DS) and not LTE, here are a few more things we can check:

  1. Check Firmware Version
    Run this command and share the output:
    ATI
    Some older firmware versions can limit LTE functionality. If the firmware is old, updating it might help.
  2. Force LTE Mode
    Try explicitly setting LTE only mode with:
    AT+CNMP=38
    Then reboot the module and check AT+GCAP and AT+CPSI? again.
  3. SIM Card & Network
  • Confirm your SIM supports LTE on Lycamobile’s network. Some Lycamobile SIMs or plans may only support 2G/3G.
  • If possible, try a SIM from a known LTE provider (like Telstra or Optus) just to verify the module can connect in LTE mode.
  1. Check for Network Restrictions
    Some providers restrict LTE for certain device types or SIM plans. Contacting Lycamobile to confirm LTE data support for your SIM could be helpful.
  2. Try the Manual Network Scan
    Run:
    AT+COPS=?
    This scans available networks and may give clues if LTE networks are visible.

Best of luck with these steps :slight_smile:

Hi.
How are you?
I am going to detect cars in the street and send sms to my phone using raspberry pi, raspberry pi camera, SIM7600E finally.
But sms include link which car screen uploaded, so that I can check the image on my phone by clicking that links.
So, I think the internet connection is necessary.
Without internet connection, Is it possible?

Hey @Doan298282,

From the sounds of it, the SMS messages should go through without an internet connection, but I don’t believe the image links would work correctly without an internet connection.

If the image links are important to you, then I would keep this setup connected to the internet.

Hope this helps! :slight_smile:
