We are traveling to Europe (France and Italy) with iPhone 6.
1) How do we set our phones to avoid roaming and other charges BUT allow still wireless? (I'm assuming wireless would not cause any additional charges)
2) Any good wireless apps that would allow us to stay connected with family and friends via wireless service?
As soon as you take off, put the phone in airplane mode. When you land, keep airplane mode in, bit only turn on wifi.
THere eyre are many apps to stay in touch such as Skype, google voice and hangouts, what's app. Etc. verizon message + will allow you to send and receive text messages over wifi with no international charges.
