hello all. We will be on holiday in November and we usually just switch off our mobile phones for the whole duration of our stay. However with the new "My Magic Plus" and the "My Disney Experience" app, and the implementation of wifi in the parks and resorts, I would like to stay connected to the internet to make use of the new systems. We will also have friends with us on this trip and they are staying in a different resort so it would be useful to be able to stay in touch using either facebook or iMessage. I was just wondering what people do to avoid mobile phone data charges. I do not want to make or receive phone calls. Nor do i want to use text messaging. will switching off data roaming in the phone be enough? What about leaving the phone in aeroplane mode, will this then also disable my wifi? What if I remove the sim card, would i then be able to just use the phone as a wifi device? Any advice or experiences would be appreciated.
