I would like to know this as well. Ian, I have an Iphone as well, what all do I need to turn off while on the ship? And do you know how expensive it is for internTional calls? Thanks
I think the rates vary by country, but the first step is having international access added to your account. I think it's about $20, but you can call AT&T after the cruise and have it removed.
To disable email, you have to go to Settings and then go to Mail, Contacts and Calendar.
Then tap on each account (I have 8 email accounts) and at the top of the screen for the email account, you will see "Account" and an On/Off switch. You're going to want to switch each of your accounts to "Off" which will prevent it from getting mail, and thereby accidentally run up charges.
Another item to disable before getting on the cruise is Location Services, which is basically the iPhone's GPS feature and used with Google Maps and Geotagging photos. Location services is in constant communication with networks, which is how it devines and triangulates geographic location.
To switch off Location Services, go to Settings, General. You will see "Location Services" you will want to switch this to off, before you get on the ship.
The most important thing to turn off, is Data Roaming. This should already be switched to "Off" but check to make sure. Having it switched to Off makes sure that for data (email, web browsing) there is no roaming when not in the US.
Go to Settings, General, and tap on Network. You will see Data Roaming. Make sure this is off.
Now you may wonder why not just do this and not bother with all the other stuff. Well, we will be on the Magic, which has cell service throughout the ship. At times we will be in the US and at times not. I think it's better to be safe than sorry, and accidentally have things like email connecting and therefore racking up charges.
Regarding Safari, you will just have avoid using it, as well as any applications you might have on your iPhone that might connect to the network like Facebook , Google App, iTunes Store etc.
Still wondering how people are dealing with emergency contact while away and at sea.
