The Telecommunications Company of Cuba, S.A. (ETECSA, for its acronyms in English)  was founded in 1994 then with a corporate purpose of provision and marketing of public telecommunications services. It was not until December 16, 2003, when Cubacel and C_COM merge into ETECSA, integrating in a single joint venture all activities related to landlines, cell phones and other telecommunications services; reason for which, we celebrate on this date the anniversary of our Company.
