"Sometimes we would be in the street waiting and we would think, where are all the taxis? Now you can call them using the application, not calling them directly but you can publicise your trip and any taxi available can respond to your request."

"The challenges are trying to achieve the best communication (reach) possible, with businesses outside (of Cuba) as well local, in order to create a purely Cuban project, that is a project created here for the world and for Cuba."

In the two-and-a-half months since Cuba allowed its citizens internet access via cellphones, the fast-charging changes are subtle but palpable as Cubans drag what was once of the world's least-connected countries into the digital age.
In the first 40 days since Dec. 6, when people could start buying internet access packages for 3G service, 1.8 million Cubans - out of a population of 11 million - purchased the services, and a government report last week said that about 6.4 million residents are users of internet and social networks.
A group of young people launched Sube, a ride-sharing app for clients to hail aging American sedans on the streets of Havana.
"Sometimes we would be in the street waiting and we would think, where are all the taxis? Now you can call them using the application", said Claudia Cuevas, 26, a university professor and fellow member of the Sube team.
Previously, nearly all Cubans could use their mobile phones only to get their state-run email accounts unless they connected to the internet at a limited number of government-sponsored Wi-Fi spots.
Government officials and foreign businesspeople could use their mobiles to access the 3G network in recent years, though not always reliably.
The history of the internet in Cuba has been rife with tensions and suspicions since it began in the 1990s.
Cuba accused Washington of blocking its access to the fiber optical cables near the island, forcing it to use an expensive and slow satellite service.
It was only in 2011 that it got access to a submarine cable with the help of Venezuela.
And it wasn't until 2015 that the general population gained access through the opening of Wi-Fi points in hundreds of parks.
Critics of Cuba's communist government said it resisted giving its citizens free access to the internet because it feared a free inflow of information, while its supporters noted that it was fighting efforts by Washington to undermine its government and revolution.
Julio Aguirre Lusson, 25, a DJ who has a YouTube channel called TecnoLike, says he has noticed the impact.
Aguirre said, however, that there are still many limitations from both outside and inside Cuba.
For example, there are obstacles facing local developers who want to enter their products in places like Google Play Store.
And in Cuba, developers face a paralysis in the delivery of operating licences so they can work within a legal framework.
Cuban President Miguel Diaz-Canel opened a Twitter account prior to December and recently ordered all his ministers and senior leaders to do the same.
Diaz-Canel, who is an engineer by profession, has repeated the importance of the internet in general and said authorities are working on websites and platforms to provide government services, such as requesting a birth certificate, knowing the status of a file or computerising government forms that are still filled out by hand.
