This device can be wired to an electronic gate opener or garage door opener. By calling the phone number assigned to the SIM chip (SIM chip not included), the device will activate a relay, which can be connected to the trigger on the gate, or the gate motor itself.

There are no call costs incurred when dialing the unit; it will recognize an authorized telephone number calling it and reject the call without answering.
