Web-based phones and free online messaging services can't be used in Cuba as internet access is highly restricted which annoys millions of Cuban in and out of the country.

Cuban telecommunications monopoly Etecsa Friday authorised Cubans to send text messages to the United States, lifting a restriction which has long frustrated the population.

"From December 8, 2017, you will be able to send text messages from any mobile phone internationally to any mobile phone in the US," the firm said on its website.

It also stressed that the $0.60 charge for sending messages to the US is "similar to other international destinations."

More than two million Cubans live in other countries. With most in the US, the lack of a direct messaging service has been a long-time complaint.

Web-based phone and messaging services are generally not an option in a country where internet access is highly restricted.

A historic reconciliation 

The announcement comes at a delicate time for the two countries, which reestablished diplomatic relations in 2015 after half a century of tension.

After the historic reconciliation, Washington eased the embargo in place since 1962, and authorised US telecommunications companies to sell their services in Cuba.

In February 2015, Etecsa and the United States' IDT Domestic Telecom, Inc reached an agreement which set the ball rolling on the first direct telecommunications connection between Cuba and the US - although it was initially only for landline telephone calls. 

However, ties between the two countries have newly deteriorated over alleged acoustic attacks against US diplomats in Havana. 

In September, the US Department of State reduced the number of embassy personnel by half, suspended visa services, and expelled over a dozen diplomats from the Cuban embassy in Washington.

US President Donald Trump in November also announced the implementation of new economic sanctions and travel restrictions on the island.
