Yes, you can use your Australian Uber account in London without making any changes to your profile. The Uber app is designed to work globally in over 10,000 cities. When you open the app in London, it will automatically detect your location and display local vehicle options like UberX, UberXL, and even Uber Boat on the Thames. The app will continue to use your chosen language, and while the fare will be calculated in British Pounds (GBP), Uber will automatically handle the currency conversion with your linked bank or credit card. It is highly recommended to have an international data plan or a local eSIM active, as a stable internet connection is required to request a ride. You do not need a local UK phone number, as long as your registered Australian number is active for any necessary driver communications via the app’s VoIP system.
