For most Shell stations you must plug the connector in the car first and then starts the charge in the app. But some Shell stations are the opposite... Help others by sharing your experience in the "Comments" section. Please report steps taken for a successful start.
You can activate it using this app, it works perfectly, however, one night I left my car charging and came back the next day to get it because I live nearby, there was a warning on the windshield saying that I couldn't leave it charging at night or my car would be towed. Parking is public and open.
