I Remember hearing about an app that was suppose to allow you to restrict data usage on android phones. Essentially I don't want a data plan. (Don't try to reason with me here, I have my own reasons and logic for wanting to do what I want to do) I am looking at a phone that won't require a data plan because, my provider won't have the imei. What apps can I use to make sure no data get used? Essentially only data I want to be allowed in or out besides calls/text would be data over a wifi network.
