I will be traveling to Europe in a few months and will be taking my iPhone4 with me. I want to avoid spending a fortune to use my phone while I'm there and have the Line2 app (I will forward my normal calls to my Line2 number) and will pay for a month's worth of service. I know that I can disable cellular data and data roming but I want to know if it is possible to ensure that my phone does not connect to any local cell networks and only connects to available WiFi networks, is this possible?
I live in Germany and I can tell ya now that you will not be using your phone much unless your hotel has free wifi. There are not many places that have free wifi. I was in the states last December and most stores and restaurants had wifi. It was great! Traveling within Europe I cannot use my phone outside of Germany without racking on roaming charges. I have had a couple of large bills when my husband and I got lost in a few different places and used the maps app. Cheaper to buy a European navi. Make sure whatever hotel you stay at has free wifi.
