This week all 4 major US carriers now allow their customers to roam in Cuba. With voice charges as high as $2/minute, it seems like a reversion to the old days of cellular roaming, but roaming in Cuba is a big deal. Data roaming is an even bigger deal in that even wi-fi is not yet widely available. When you do find wi-fi, some carriers, most notably T-Mobile, allow FREE calling to the US with Wi-fi Calling. The trick is finding free wi-fi.
This is an unusual situation in that the CDMA carriers offered roaming before the GSM carriers in a GSM country. We have an updated report on wireless roaming in Cuba at CellularCuba.com. There you will find options for calling both TO and FROM Cuba. In some parts of the US readers are wondering 'what's the big deal?' The closer you get to Florida, the bigger a deal this is, and someday we may travel to Cuba as readily as Canada or Mexico. It's a short trip and a different world. It's good to have our phones now work there.
For those of us who don't have the right plan or are using Prepaid, Mobal Wireless can provide a SIM we can drop in our phone that roams in Cuba. Also, visitors returning from Cuba advise you use your phone discreetly in Cuba. There is a certain amount of resentment toward visitors to Cuba showing their weath in a such a poor country. Now let's hope technology can get the price down.
