Boost Mobile from Sprint is offering prepaid calling cards for Miami customers to call or text Cuba.

Sprint's subsidiary company is selling $15 prepaid cards for a limited time only that allows customers to talk for 50 minutes.

According to the Associated Press, the company announced that it would allow customers to pay $50 a month for a card that includes 5 gigabytes of high speed data where they could talk on the phone for 15 minutes with unlimited texting. Boost Mobile also has a plan for $60 a month for 10 GB of data.

Meanwhile, T-Mobile's Latino-first brand, Univision Mobile, has updated plans to include minutes to Cuba and all other Latin American countries. Univision Mobile already has unlimited texting to Cuba in each phone plan with more voice minutes and LTE service.

T-Mobile's $45 plan allows 20 minutes of calling time to Cuba and its $55 plan allows for 24 minutes.

The company is "No. 1 for international, at no extra charge," according to T-Mobile's release.

Cuba charges some of the highest rates for long-distance calling in the world. Calls into Cuba are often very expensive as well.

A New Jersey-based company called IDT Corp. recently started a deal with Cuba's state telecommunications company that allows customers to make direct calls between the United States and Cuba.

Back in December, both nations started negotiations to restore relations after a bitter relationship in the past five decades. Most recently, the Obama administration has removed Cuba from the list of state sponsors of terrorism, Los Angeles Time reports.

President Barack Obama said the world has changed since the Cold War and many other disputes that led the U.S. to putting Cuba on the list in the first place. Removing the island nations from the terrorism list joins with other recent indicators that the U.S. government will begin lifting embargoes and will continue to loosen restrictions on travel, trade and international banking.
