Nowadays, most ships have Wifi available aboard at a price. Calls at sea are handled by a marine telecommunications network and the cost of roaming charges can be pretty steep.
The signal strength can vary substantially from hour to hour and waiting for a web page to open on your computer screen can be frustrating.
Check with your local mobile operator for the international roaming rates applicable to your tariff. Turn off Data Roaming and stop your apps from automatic updates to save on charges. Don’t forget to turn off all the push notifications. Rather have a digital detox and enjoy your journey on-board!
Most ships have an internet package that you can book prior to your cruise, that will often be much cheaper than paying per minute aboard.
