If you would like to avoid that cost overruns caused by your mobile on a cruise, we give you some advice, one of them is obvious: turn off your mobile, but if you are not capable of it, then you can activate airplane mode or deactivate roaming. When you are browsing you have to be very careful with borders, since our device can connect to a foreign network if it loses coverage with our local network.
Most the big ships have equipment installed that provide access to networks via satellite, to which our devices will connect when the port is left.
Remember that as are the telephone operators it is easy to expose yourself to excessive fees in case of accepting a call, sending a message or simply leaving the data activated.
We give you a series of tips before putting the phone in the luggage.
E.g. use the phone only when you are on the ground, keep it off on board and if you want to take photos or use the terminal for other things you can activate airplane mode. If you decide to keep the mobile operational, I recommend that you look at the network name to which we are connected, to know when you are connected to the ship's satellite network and when to that of the local operator.
Consult roaming rates. The latest European regulation has significantly reduced prices by up to 55% compared to two years ago. There is also the option of prepaid cards to make international calls.
You can call or write from the ship's computers. You may have to pay for the Internet connection, but it will always be cheaper. If the ship has a free or paid Wi-Fi network for passengers, and we connect to it from the mobile, always make sure that the phone data is deactivated.
I think these tips will help you avoid unpleasant surprises when the phone bill arrives after a pleasant trip.
