My daughter has an iPhone 3g. She's really careful with credit but it's all gone within days. She doesn't ring anyone our use internet, only the I'd text. Does anyone know why this could be happening?
The first thing to ask is how much allowance does she get? i.e. how many voice minutes, texts and data does she pay for? And which of those is she using up quickly?
If she is on PAYG, the phone could be connected to the net all the time, which would use up her credit, even though she doesn't actually use the net.
I'm told that to turn off net connectivity you need to go to Settings, General, Network and turn off the ones not needed. Might be worth trying, or checking out.
on that consumer prog the other morning they were saying that some apps automatically update "in the background" ie without you asking them to every day at least and sometimes more. to do this they connect to the internet
