Cruise Ship Mode? (Phone off, WiFi on)

One workaround that I used is to enable the SIM PIN feature to lock your sim. Then reboot your iPhone and leave the sim locked. With the sim locked, EDGE and voice won't work, but Wi-Fi still works.

Go to Settings > Phone > Sim Pin and enable. The iPhone ships with a default PIN of 1111.

Then, when you need to make a call, you must reboot your iPhone to unlock the sim. It is a bit of an inconvenience, but on a cruise ship, who cares about time, right? Relax.

(To reboot, hold the power button on top down until the red slider appears, then power off. Then power back on. When powering up, you will get a sim unlock option.)

best thing is to either cal At&T and temporaril deactivate edge or just keep the sim out...data using while roaming is risicously high. I wouldnt even consider that ot usig the actual phone. I have heard some horror stories. I would just pop the sim out and keep it n a safe place.

Yup. I am aware of the difference. In my own experience, the first time I locked the sim card using the security feature I got a mesage on the screen asking for the PUK number (right after I entered the default pin number).

Maybe I did something wrong and didn't notice.

Here is one other option for you or other world travelers.

AT&T offers international roaming for iPhones

Horror stories of four-digit cellphone bills after taking the iPhone abroad need not repeat themselves, says a second report from Ars Technica.

In a simple reminder, the site points out that AT&T's iPhone Center provides information on the carrier's World Traveler service that lowers calling and data rates substantially for subscribers who regularly expect to travel abroad. The service typically costs $6 per month on top of the existing iPhone bill.

Users anxious about data charges while abroad were also reminded that Apple's third iPhone update is expected to allow disabling of the EDGE cellular Internet connection without cutting off phone access, as with today's Airplane Mode.

....OR...You could wait for the update sometime this century, that is suppose to give you the ability to turn "OFF" edge.

Hope that helps

Good Luck and enjoy your vacation!

AT&T told me their "World Traveler" discount plan does not apply to Cruise Ship roaming. The Cruise Ships have their own onboard cellular system. No discounts. I think the rate was something like $2.49 per minute, and $.50 per text message, although not positive (I haven't received my bill yet!)

Call AT&T to have them suspend your service whilst you're away.

Or just remove the SIM card.

then to answer your question accurately to your needs, with the current update it is not possible to enable a cruise ship mode... Honestly how many days are you on a cruise a year?

It's not as simple as you may think. If you lock your sim you'll have to call at&t to get a PUK number... keep that in mind.

Abelardo,

Locking your SIM card using the security feature is not the same as the SIM card blocking you from use after several failed attempts when entering the incorrect SIM lock code.

Brilliant!

You can often get the PUK for your sim from the AT&T website. I got mine there.

I think your wish was just granted in the 1.1.1 update. Goto:

Settings, General and turn off Data Roaming
