On my iPhone, I have gone to Settings, then to General and then to Network. There, I have switched Cellular Data Off.
Also in Settings, I have enabled my home WiFi.
I will be in Bali again this month.
When I am in Gloria Jeans in Kuta Square this month, I will enable their free WiFi network and enter the password which they will supply to me.
This way, I do not pay for celluar data downnloads in Australia or Bali, ie. data from mobile phone companies.
