Buy & Activate SIM Card

Purchase a 2G/3G GSM SIM card from a cell phone provider in your country. See the Supported Carriers page for more information on which carriers are supported.

Activate the SIM card on a pay as you go plan. Only talk and text is required; do not sign up for data. This should typically cost $10 per month in many countries.

Install SIM Card

Open the case and slide back the latch to allow the SIM card to pop up. Insert the SIM card into the slot and ensure the metal contacts are facing down towards the board.

Power Up Device

Connect power to the device (DC or AC power depending on the model).

Ensure Network Connectivity

The D2 LED (network connectivity LED) should flash rapidly as soon as the device powers up. It will blink slower or turn solid as soon as the device successfully registers on the cell phone network. This means the device is active and can send and receive SMS messages and phone calls. If this light continues to blink rapidly, it means that the device was unable to connect to the network. See the Troubleshooting Guide for details on how to resolve this issue.

Add Phone # to White List

Send the following command to the phone number of the SIM card that was purchased and registered with the cell phone company:


Where 1112223333 is the phone number of the phone you will be using to call or send SMS's to the device and 001 is the position in the white list where the phone number is being stored. To program another number, change 001 to 002, etc. Include the area code, but EXCLUDE the country code. The phone number should be 10 digits long. The D6 LED (RX/TX LED) should blink rapidly to indicate the device is receiving a message. To clear/remove a phone number, use this command:


Test Device

You should now be able to trigger the relays on the device via SMS or phone call. Try calling the phone number of the device and listen for a clicking sound to indicate that the relay was triggered.
