Now that the political relations between the US and Cuba have taken a turn for the better, American companies are pushing out marketing schemes to fit the bill. Today, Boost Mobile, Sprint's prepaid branch, announced a monthly plan that's geared toward customers who have loved ones in Cuba. The caveat, unfortunately, is that it's only available in Miami right now -- but the strategy makes sense, since it's a city with a dense population of Cuban-Americans. If you're there, $50 a month gets you unlimited text and 15 talk minutes to Cuba at 33 cents per minute -- which the company claims to be the lowest rate among prepaid carriers. Boost's Cuba Monthly Connection deal also includes 5GB of data and all-you-can-have texting and calling within the US, while $10 more monthly doubles your data.
