It turns out on Android at least that apps can turn the radio back on. Data can be over 1xrtt as well so turning off data is not enough to block roaming, you must turn off the radios.

Hi guys,
Need your help with some settings configuration confusions. I am new to android phones, as have been using iphones all the time, until mine got stolen, and before the new one is out I decided to get Xperia to be able to use all the apps such as Whatsapp or Viber..
Anyway, THE ROAMING issue. After purchasing the phone and looking through the settings, I switched off Data Roaming, because I travel to Belgium from Luxembourg often these days. And I was pretty sure not to worry about it, while abroad... But then suddenly I notice while in Belgium, that the data is still being transferred and I receive all the Whatsapp, Viber messages.. emails. I checked Roaming again, it was definitely off! Also of course I checked Wifi, no networks were available. The only thing I could do then is to completely disable the data traffic.
So I'm a little confused here with the function of Data Roaming on this phones.. and disappointed..
And of course, maybe it is something that I do not know about androids.
It would be great if someone could explain
Thank you!
