If you need to let your driver know something before the ride, you have the option in the app to type a short message that they will see as soon as they accept your booking.
To add a message for your driver, please follow the following instructions. Go into the app and enter your destination, once that is done tap on your desired vehicle type and you will see the option “Message Driver” under preferences. Add the message to your driver and press save. This message will be visible to the driver that picks up your booking however, if you would still like to call your driver, you can always do that by tapping the telephone symbol.
