Telecommunications in Cuba consists mainly of NTSC analog television, analog radio, telephony, AMPS, D-AMPS, and GSM mobile telephony, and the Internet. Telephone service is provided through ETECSA (Telecommunications Company of Cuba), mobile telephone service is provided through the Cellular Telephone Company of Cuba (CUBACEL) and, previously, Caribbean Cellular (Celulares del Caribe, C-COM - no longer operating). Cuba's main international telecommunications links are through Intersputnik, with limited effectiveness of undersea telephone cables to the Americas, Spain, and possibly Italy due to underdevelopment.^[1]

Telephones – main lines in use: 1.2 million, 72nd in the world, less than 10 per 100 inhabitants (2009).

Telephones – mobile cellular: One million mobile phones at the end of 2010 (9 per 100 inhabitants), up from 621,000 in 2009 and 330,000 in 2008, when all Cubans were allowed to buy and use them for the first time. Mobile-cellular telephone service is expensive, which limits subscribership.^[2]^[3] By the end of 2020, Etecsa announced that they had 6.661 million mobile telephone users of whom 4.421 million had Internet.^[4]

Telephone system: 95% of telephone switches were digitized by end of 2006.^[3] The principal trunk system is coaxial cable; fiber-optic distribution is used in Havana and on Isla de la Juventud; two microwave radio relay installations (one is old, US-built; the other newer, Soviet-built); both analog and digital mobile cellular service established; one international satellite earth station, Intersputnik (Atlantic Ocean region).

New fiber-optic link: A new undersea fiber-optic link with Venezuela was scheduled for 2011.^[5]^[6] In May 2012 there were reports that the cable was operational, but with use restricted to Cuban and Venezuelan government entities. Internet access by the general public still used the slower and more expensive satellite links,^[7] until January 2013 when Internet speeds increased.^[8]

Access to the Internet was heavily controlled, and all e-mails are closely monitored.^[14]^[15]

The Cuban authorities have called the Internet "the great disease of 21st century" due to 'counter-revolutionary' information being available on a number of websites, some of which are official news sites.^[16] As a result of computer ownership bans, computer ownership rates were among the world's lowest.^[15] However, since buying a computer was legalized in 2007, the ownership of computers in Cuba soared, dramatically increasing the number of Internet users. But, the rates still remained quite low, partially due to the high costs of systems and Internet usage per hour in contrast to the average monthly wage.^[14]

In 2019, ETECSA began offering Internet connection via Cubacel mobile telephones which was increased with 4G. In March 2021, they announced that 4G had reached every municipality in the country.
