We'll be sailing on the Conquest (Carnival) Jamaica, Grand Caymen & Cozumel. We have 2 older teens & use our cell phones (Verizon) to stay in touch. Will they work on the ship or in any of the ports? How about our laptop, wireless? Will it cost a lot to go online? Techies, afloat!
there are no cell towers in the middle of the Caribbean. You will only get service when you get close to an island that has service. Call your provider to find out if you have service and if the islands are in your home calling area, if not you could be paying whopping roaming charges.
