I've recently (2 months ago) purchased my first smartphone. I'm on a sort of prepaid contract (I pay what I use in terms of calls and SMS and it's automatically withdrawn from my bank account).
For years I have been paying like 6-7 EUR per month (at the most!). I don't like using phones in general and smartphone is a new thing for me but I bought it just for the cheap GPS and camera (not the mobile surfing). After the first month I got a surprising 30 EUR bill. Every once in a while I was getting notifications about new mail, or Skype messages etc. and I was wondering why this was happening (I know, I sound like a member of the Flintstone family) because I never enabled mobile data transfer. As it seems it is turned by default.
I went to my service provider and the guy deactivated the data connection. To my question "Can I just block any Internet activity through cellular connection for my number?" he told me that it's not possible (why he did not explain). Just to make sure things were all set I even put a data cap on cellular data at 10KB. In addition I have also limited updates of apps only to WiFi that is if I'm connected to a WiFi network only then apps should check for updates and download those.
I've just received my bill for last month (the second month of me using the smartphone). And this time it was just painful - 81 EUR. I checked my bill's details and I saw the following strange reoccurring Internet traffic:

All in all 68 EUR without VAT, 81 EUR with it.
Needless to say I am far from happy.
I started digging and checked the data use for every single app. Almost all apps had the background data use (cellular connection) enabled by default. I wan't sure what the background data is so I read a little bit.
The descriptions is also useful namely: Enable usage of cellular data in the background.
I checked some of the apps (like YouTube) and I saw that while 80% or so of the traffic was foreground many times there were couple of hundreds of megabytes background data.
I disabled all background data use now for all apps but I wonder if that is not the case why I got that fat bill. If that's the case there are multiple things that bother me namely
- why did the cellular data limit not kick in? In the stats for cellular data I still get literally no data being used
- why even with data connection disabled cellular is used at all?
- why am I not getting Skype, Hangouts etc. messages, new email notifications, Chrome shows I'm offline etc. if cellular is indeed enabled?
Especially with Google Photos (I have syncing between my phone and the online service enabled) the situation is horrible - 466MB foreground, 2.08GB background between 10th of May and 7th of June.
What else am I missing? Clearly the guy at the shop didn't help and I'm very new to this smartphone thing. I simply want to use Internet (any sort of Internet connectivity) ONLY when I'm connected to a WiFi network (home, work).
