Did the lack of technology create a higher literacy rate in Cuba?

Cuba is one the few countries in the world with limited technological growth. Not because of resources or funding, but rather the government sanctions which limits this growth. While the internet has been around for several years now, Cubans have only been allowed access-albeit restricted- within the last two. The fortunate ones with access to a computer are limited to 56kbs dial-up through a government operated facilitator.

This restriction of access to the outside world has been viewed by most as a way of controlling the flow of information within Cuba. Most of the news and information comes from letters and phone calls from loved ones outside of the country. Is this the reason why Cuba has a literacy rate of 99%? Are they forced to exploit the most basic form of communication because there are no other means? I guess if I had no internet, no television and a limited amount of non-political channels to listen to, I too would be inclined to read a book. Has the lack of technology actually helped in this situation?
