As tensions between the US and CUBA subside, it is safe to assume that the government will slowly release the grip it has held on its population. CUBA's second largest city (Santiago de Cuba) will be getting public WIFI from the state owned ETECSA telecom company.
Prior to this development, citizens and visitors have had to use internet cafe provided workstations to access the internet. This means that users will now be able to use their own devices to browse the internet.
The $4.50 an hour is cheap by our North American standards but very expensive by CUBAN standards. Don't expect super speedy unfettered access through because access will still be censored.
