Ridesharing app Uber isn't just a major phenomenon in the United States.

The company's services have expanded around the world, from Cairo, Egypt, to Delhi, India. The execution hasn't always gone smoothly, however, as it has faced numerous challenges abroad in its plan for global ridesharing domination.

Europe

In Europe, the company has often seen issues with regulations, as the app has been banned in Romania and Bulgaria. Taxi drivers in European countries have felt threatened by the service, with drivers protesting the app in Paris in June 2015 and January 2016 due to concerns that the app is unfair competition.

The company has also faced European rivals, such as London-based luxury ridesharing app Wheely and Germany's Mytaxi, which operates in some German cities that Uber is banned in. In Europe's biggest economy, Germany, Uber is only available in four cities: Berlin, Dusseldorf, Frankfurt and Munich. 

In 2017, Uber gave up operations in Russia to its largest competitor in the country, Yandex.

Africa

In Africa, Uber is often seen as a scam free and safer alternative to taxis and is currently available in eight African countries.

Egypt is Uber's biggest market on the continent, with 30,000 drivers as of 2017. Uber is facing competition from regional competitor Careem. 

In other African countries, Uber has been criticized for becoming a monopoly in Kenya and South Africa. It faces stiff competition in Africa from Estonia's Bolt, which was formerly known as Taxify. 

Uber is currently looking at expanding to Senegal and Ivory Coast, two of the world's fastest-growing economies. 

Asia 

Earlier this year, Uber left eight countries in southeast Asia in a deal that gave the company a 27.5% stake to rival ridesharing firm Grab. 

Uber is still trying to win over India from local competitor Ola. In the Indian city of Mumbai, Uber even has boats for those who want to beat the city's insane traffic. 

In Asia's biggest economy, China, there are no Uber drivers to be found, as it sold its operations to local rival Didi Chuxing in 2016. 

South America

Latin America is Uber's fastest-growing market and serves as a safe and reliable form of transportation in countries such as Mexico, Brazil and Peru. 

Uber is only regulated in Mexico and Brazil. It has faced protests by taxi drivers in Argentina's capital, Buenos Aires and the Argentinian government has ordered investigations into the company's use of personal data.

Here is a list of all countries where Uber is available.
