It's a Galaxy II and he had lots of Apps on it. I added talk booster but NO data and want to be sure that I won't be charged for data if those apps are set to auto update or such thing. Bottom line, can I get dinged for data use if a font have the data booster. Thanks
If you're data-phobic, what you've done is 100% correct. Since it's an old phone, make sure your son's old contacts, accounts and preferences are zapped out or you may end up inadvertently messing up his google contacts if the phone is still signed in under his account.
