PAYG data usage on iphone (SE)
I've never had a smart phone before.
I'm on pay as you go but I'm terrified to have the iphone on to use as a phone in case apps and things that are automatically on the phone are using up my credit as data without me asking them to.
Does this happen?
Can I somehow turn off that bit? (On my computer if I'm worried I just turn off wi-fi but I don't know if you can with a phone and if the phone would still work for calls in and out and texts). If I can, how do I do that?
I also just joined i-cloud and am now worried about that too using up my credit without me actively accessing it eg I have put photos up there and some word documents to store but maybe it would be better somehow to have them on the phone.
iPhone SE, iOS 13
