Am with Telstra got mine unlocked for Free & was asked if I wanted International data roaming active I said NO of course.
Never had a prob with data roaming being active overseas when going to Thailand. Will use a Bali sim when over there in May.
Apple® iPhone™:
Step 1 of 4: Tap Settings
Step 2: Tap General
Step 3: Tap Network
Step 4: Set Data Roaming to Off or On
Note: Data Roaming is turned off by default. When you switch on your phone overseas, you'll be prompted to switch Data Roaming on.
