automatic updates?use a data usage tracker like DU meter. Then track what eats out the data.And use a bandwidth limiter like netlimiter to limit excessive data.
If you have any facebook apps on your phones get rid of all of them. Apparently there are reports of them using excessive data in the background for no explained reason.
So I've done 15 mins of browsing and I've already used up 310MB. Is this normal?
I have the dialog 4g as well. And it used to eat out data within a small period when I'm browsing, on fb, or even when on you tube.Now I use the netlimer to limit the bandwith while on internet. limited google to 150 KB/s.
If you are so unsure how your data is being spent, as I said before use a data tracker software like the DU meter
