Having looked at my recent tariff of my Virgin mobile, I have noticed that some internet connections were charged, which I never intended to connect. I wonder if my phone may be authomatically picking up VirginMedia's internet.
It has never happened before until now (I usually use another service (wifi) with free of charge).
Is there any setting I can change on my phone? (an old Xperia with Android 4.3)? Or should I just need to be careful not to connect somehow?
