Hoping someone can clarify/correct my understanding of the below.
I have a Samsung Galaxy S2 with Vodafone and am heading off to Perth tomorrow for 2 weeks holiday. I'm not interested in using the phone for calls while there but do want to use it for Navigation. My main goal is to not incur any data charges or very little.
For navigation I will pre cache the google maps, deactivate data network and place in airplane mode, i'm pretty certain that this will not incur any data.
What I'm not sure about is when connected to Wifi,with airplane mode diasable will the phone use the wifi connection to download texts, emails and will you be able to make recieve calls via wifi or can it only be done via the data network.
cheers
