I travel internationally and I do not want alot of roaming charges, how can I turn off roaming?
settings - general - cellular - data roaming - OFF
In Settings go to General > Cellular and turn off Data Roaming
You will also need to make sure that your push notifications in mail contacts calendars are tournedos off in settings.
My provider will charge for each incoming call, even if I don't answer it. To avoid this charge turn the phone to airplane mode. You'll still be able to use wifii.
