What you need

  • APN settings (this is operator-specific and can often be found by a simple Google search – otherwise contact your sim-card operator)
  • Android smartphone (referred to as smartphone)
  • USB charging cable
  • Sigfox Access Station Micro with accessories (referred to as gateway)


Step 1
Download the Sigfox Access Station Utility app in Google Play on the smartphone

Step 2
Setup the gateway like this:


Gateway → ethernet cable → IoE injector (splitter) → power supply adapter → power outlet

Step 3
Open the Sigfox Access Station Utility app on the smartphone.
Enter something random in the fields and click OK:

Step 4
Connect the USB charging cable to the smartphone and the gateway.

Step 5
After connecting the USB cable between the smartphone and the gateway, it should say Access station connected at the bottom, and details should be shown in the top box.

If not, try to reconnect the USB cable and/or restart the app until it works.

Step 6
Click on the menu in the top right corner and choose Network management:

Step 7
Click on Cellular

Step 8
You can now enter the APN settings from the operator of your SIM-card and click on Update configuration in the bottom:

If the SIM-card has a PIN-code, enter it into the field.
However, we recommend to remove the PIN-code from the SIM-card instead.

Step 9
You should then see this confirmation. Click OK.

Step 10
Disconnect the USB cable from the gateway and the smartphone and close the app.

Step 11
Insert the SIM-card into the 3G/4G dongle and connect it to the gateway.

Step 12
The gateway should now try to establish the connection, and once successful, the LED will light solid green.

If not, try to restart the gateway. Make sure there is GSM connectivity.

Step 13
Do a connectivity check by inserting a thermocouple into a Maturix Transmitter and check in the Maturix Web Portal that data is being received.

Voila! You can now use the gateway with a SIM-card from your local provider.
