Using mobile data in Cayman Islands: local tips
- Sign up for national alerts. Hazard Management Cayman Islands runs NENS, a free alert service for hurricanes, earthquakes and other emergencies that visitors can join too. Sign up via the HMCI website before exploring the islands.
- One number for every emergency. Dial 911 for an ambulance, fire, police or the police marine unit – including dive emergencies that need the hyperbaric chamber.

- Wi-Fi before you fly home. Owen Roberts International Airport has wireless internet in the Departure Hall, handy for checking onward travel details while you wait.
- Check the official forecast. During hurricane season, June to November, the Cayman Islands National Weather Service publishes warnings, radar and tropical updates for all three islands.
