I'm looking at travelling to Europe this summer and want to take my Bionic with me. I would like to turn off the mobile network and just use WiFi while I am over there. Is it possible to turn off the mobile network completely while I am overseas? When I go into the network settings I only see options to turn on/off wifi and choosing between cdma/lte+cdma. I have Skype credits and that's what I am planning on using while over there in conjunction with email + Google Voice. Would the best way to go about this be to put my phone into airplane mode and then just activate the wifi? I know this is a silly question, but I wanted to be totally sure before I rack up a $1,000 phone bill. Thanks!
