The mobile application from the Jettaxi Uman taxi service allows you to order taxis online from your pocket device on any platform. from the pros: you do NOT communicate with the dispatcher, you see in real time where your car is, you can choose the class and type of car, additional functions (luggage, car ignition, animal transportation, comfort car, air conditioner). You determine the time yourself, and the car that will pick you up adjusts the cost of the trip yourself!
