Data connection

Hi everyone,
I've found a bad behavior from monday on. I'm out of my country and I switch off the data connection to avoid extra cost of 2 euros per day. This from two years on. If I connect to data or I make a call, the italian operator will take me 2 euros and give me 30 minutes of call and 30 mb of internet. I'm out of Italy all the week and I'm not going to spend 2 euros every day, and I switch off the data connection. But from last monday 30 november, it happens. I have the data off (and the "use data if WiFi not available" disabled) and the phone automatically takes data from sim. I'm always under WiFi and it's very strange. The operator's report give me the feedback that no data were used but there is a connection. Why? How can I switch off this bug???
Thanx

U can use battery saver and also restrict background downloading while roaming... Etc etc... Even try to soft reset..see if it works... The volume down trick..

Or you can create a dummy access point... Put all wrong credentials in it.. .... So that it won't connect..even if phone want it to .... Wen u wana use it .. Activate the genuine one ..

Hi 9sag9 and thanx for answers.
I've disabled everything but I didn't try to create a dummy APN for the connection. I try it and I let you know. Tomorrow. If the mobile operator will take me or not 2 euros...
I hope.
Thanx

Permit to let me a little reflection. This dummy APN is not normal. If I disable the connections, I'll disable at all, not "maybe", don't you?

Good morning,
The problem probably was onother feature: the feedback. If I disable the feedback, it doesn't check if data connection is available. This is a bug. Now I've disabled it and the problem disappears.
Maybe... :D

That's great... I prefer a dummy APN .. It works great for me... Because my phone won't reach the sky .. Even if me wants to with wrong credentials.. ...
