Good afternoon.
Just an advice for people that is making this question: REMOVE THE CHIP FROM YOUR PHONE IF YOU ARE TRAVELING ABROAD AND DOESN'T WANT TO USE IT!

Ok, seems like an error, but when I contacted support, it was said that "there's nothing I can do" and that was it! Let me put it in a way: even trying, there's very few ways in which youl'd be able to use that low of a consumption. That is a really annoying thing, and I never seen something like that happening before.
