Wireless connection in Cuba has grown by leaps and bounds between 2013 and 2017. Previously restricted to government officials, there are Wifi "hotspots" in many parks, restaurants and other locations. It is no longer impossible to check emails, web sites, Facebook, etc on a daily basis. A internet card will cost about $5 cuc per hour and can be easily purchased. Once you are connected you will be able to text and call back to the U.S. This has arguably been the singularly most rapid advancement in Cuban culture in the past twenty years.
