I'm going to Cuba soon as well. Has anyone figured out the cell phone situation? I have an AT&T iphone 5, an unlocked (T-Mobile) iphone 6 plus, and an unlocked Amazon Fire (android phone that uses a micro sim card.). I am mostly interested in calling back to the U.S. The calls don't need to be super cheap, but I don't want to spend a fortune and I am not the most tech savvy person, so I am looking for something easy. I am having trouble figuring out what kind of sim cards are easily available there. Has anyone else dealt with this yet?
