Tips 7 Settings for iPhone 4 and 4s:

1.  If you are going to forward your number, do so before you change any other settings (Settings->Phone->Call Forwarding->Turn ON->Enter number to which you want calls forwarded)

2. Disable 3G (Settings->General->Network->Cellular Data->OFF). Also check your Data Roaming; it should be off by default, but for some reason if it is on, turn it off here as well

3. Make sure WiFi is enabled (Settings->WiFi->WiFi->ON)

4. Turn of automatic pushing of email (Settings->Mail, Contacts, Calendars->Fetch New Data-Push->OFF and set Fetch to Manually)

5. Put the phone in airplane mode (Settings->Airplane Mode->ON)

6. If you wish to reset the usage counter to zero in order to monitor it throughout the trip and ensure usage remains at zero, go to Settings->General->Usage->Cellular Usage->Reset Statistics


NOTE: In my 4s I do not turn off Location Services and Notifications, as they both work over wifi as well as a cellular network. Disabling 3G and putting the phone in Airplane Mode ensures that they will use only the wifi network and not rack up expensive roaming charges.When I arrive in an international destination, I simply log into an available WiFi network and Voila! I have access to the Internet, email, Twitter, and can even make international phone calls with the iPhone Skype app without incurring cellular charges. When you return to the U.S., simply reverse the process, although you may choose not to reinstate the International Roaming and International Long Distance feature.
