Dominican Republic

Resort Wi-Fi often doesn't reach far buildings, the beach or the pool area, and can get overloaded at peak times. Mobile data works independently of the resort's network and covers exactly the spots where Wi-Fi is weak.

There's no coverage at all on the boat ride through the mangroves and open water, and the island itself has only weak, unreliable signal. Treat the excursion day as a day without connection and prepare beforehand.

In the Punta Cana and Bavaro hotel zone, a hotel transfer or an official taxi stand is more common. Santo Domingo is closer to a typical city, but it's worth checking with your hotel what's normal there.

The region has a hurricane season from June to November, and airlines sometimes adjust schedules for weather. Having your own mobile data lets you check flight status and reach your airline quickly, rather than relying on an overloaded hotel Wi-Fi.
