LTE Modem and AP Region SIM Not Connecting to Australian Cellular Network

Raspberry Pi Network HATs 3G/4G&LTE Base HAT
1

Hello,

I’m setting up a test rig for a radio tag data recording station, using the SensorGnome v2 software, which supports a cellular data interface. The configuration is a Raspberry Pi 4, with the LTE Hat and Telit modem from the SixFab IoT Kit (Asia-Pacific/ Australian version). The SixFab SIM card is S/N: ***, ICCID: ***.

I thought I had successfully activated the SIM card on the SixFab site, using the initial $25 credit supplied, but the SensorGnome software does not report a working connection to the local cellular network (although all three of the standard carrier networks are reported as being visible). When I replaced the SixFab SIM with the SIM from my mobile phone, the modem appears to connect successfully.

Have I missed a step or made a mistake somewhere with the SIM card activation process? Any troubleshooting suggestions are appreciated!

On a side note, do you have any idea when more stocks of the IoT kits might be available?

Regards
Andrew Hide

Hello,

Looks like my mobile data connection is now up, so I’m assuming it was just some latency in the carrier database updates?

Hi,

Thank you for reaching out and providing detailed information.

It’s great to hear that your modem works with your SIM—that’s a good sign the hardware is fine!

SIM Activation Confirmation

Please make sure your SIM card is fully activated:

  • Log in to your Sixfab Connect account.
  • Go to the Assets section, find your device, and click the Details button.
  • Make sure the Active/Deactive toggle at the top right is switched to Active.

APN Configuration

Ensure that the Access Point Name (APN) is set correctly for the Sixfab SIM. The correct APN for Sixfab SIM cards is:

super

Network Registration Details

Since the modem detects the local carriers, we suggest verifying whether it is registering to one of the networks. Run the following AT commands via Minicom or another serial terminal:

AT+COPS?  
AT+CREG?  
AT+CGATT?  
AT+CGDCONT?
AT+CSQ

Note: Your Sixfab SIM card has a monthly data limit of 100MB. If this limit has been exceeded, the connection may be interrupted. To resolve this, you can upgrade your Fleet’s data plan as follows:

  1. Log in to your Sixfab Connect account.
  2. Navigate to the Assets page.
  3. Click on the Details button for the specific asset.
  4. Change the Fleet from the dropdown list.
  5. Click on Save Preference to apply the changes.
