I have been using uber taxi for more than a few months.uber taxi can be easily booked through uber app which is freely available on play store.uber app connect you to a taxi available nearest to the place you are at.uber app is gps enabled so it will detect your location an send it all the available cabs in your vicinity.after that the details of nearest taxi available to you will be send to you with the contact number.the driver will get your location on his device so you dont need to explain your location.the driver will reach to your place in a short span of time and and pick you after clicking the start ride button.when you reach your destination the fair will be displayed and you can pay through either by cash or by some e-wallets.
