Furthermore the Single Way GSM Intercoms accepts nearly every mobile network sim card.

When a visitor arrives on site they press the stainless steel button on the front of the panel. This rings the required apartment/office and sends a noise from the intercom telling the visitor it is in operation. The apartment/office owner answers the phone. If they want the visitor to have access they press a key on their phone. This clicks a relay in the  GSM intercom allowing the door to open. Furthermore if the apartment owner does not answer their phone, the unit rings a second number programmed by yourselves.
