Is it easy to make telephone calls from Havana? How about sending or receiving faxes?

There is no AT&T, MCI, or Sprint access numbers from Havana.  You can only dial direct.  Cuba’s country code is 53 and Havana’s city code is 7.  The rate per minute to call the United States from the hotel is about $2.50 per minute.  It is also possible to buy telephone cards and use these in one of the many phone boxes in Havana.  The hotel may have them.  The 20CUC card allows about 15 minutes of talking.  The per minute rate at phone boxes is about $1.40.  Sometimes it may take dialing a number two or three times before you make a connection.  Calling from your room is very expensive.
