Mobile data turned on itself

[anemcova]

Hi, I don't get it. I just found out my mobile data turned itself on without me even knowing it. I don't use mobile data at all, since I'm usually connected to wifi, so I have it turned off and it still seems like it's turned off, but I received a message, that my mobile data is on and also I had to pay for it, which really sucks, because I didn't turn it on, I didn't even have my phone in hand at the time in fact. I'd be alright with it, but it costs some money of course and I don't use it at all, so it's just a total waste of money. Could some good person at Vodafone at least fix it so that it wouldn't happen again?

You cannot force the phone to use Wi Fi in the same way as you describe with Android phones but in settings you can select each app separately and set which ones are allowed to use mobile data and which are not. Turn them all off as well as mobile data generally and you should be properly safeguarded.
