I travel a lot for a living in many countries with my IPhone X and I would like to know why I randomly get data charges on my bill when my “data roaming” ALWAYS stays at off.
Some people are suggestions to turn off data completely when abroad but then I thought this was the functionality of this “data roaming”. To avoid data charges when abroad.
iPhone X, iOS 13

Not exact, I get charged randomly by Bell when abroad even with data roaming off. 3 times this month only.
I was explained that it is a very little amount of data, 0.0977 mb used to interrogate the server, but it is enough to activate the “Roam like home” service at 12$ per day.
