I use Android 4.0.4 (ICS).
The problem is that sometimes mobile internet (not Wifi) accidentally gets enabled
(i.e. the notifications window gets pulled down and the "Data" button gets pressed).
Then, any of the apps I use, be it gmail, twitter, instagram, viber, etc might connect to the internet, so I get charged for mobile internet usage
So, is there a way to permanently disable mobile internet
so that I don't get charged even if it's accidentally enabled?
I've tried making a new APN account in
Settings | More... | Mobile Networks | Access Point Names
with all it's settings empty (i.e. I just set a name to it, and making it active)
but I'm not sure if that's enough.
Is it a solution to manually "set mobile data limit" to zero
?
(Can I do that? I'm asking because that setting only appears after you enable mobile internet, and I don't want to do that because I would get charged)
Or is there another way?
