As an option, the OttoPark can be fitted with a GSM SIM card known as an "M2M" or "Machine to Machine" card. This card only works for machine-to-machine communication, not for telephone calls.
All you have to do is call the OttoPark from your mobile phone or landline to operate it. As soon as it rings, if it's in the down position it will go up, if it's in the up position it will go down.
It works in the same way by sending a text message. You can manoeuvre your OttoPark from New York if necessary to free up your parking space in Nice for a friend or relative. The subscription is a contract like the one you have with your mobile operator. It costs less than €5 per month.
