Alright guys, what I need is an app or a way to make my phone use my wifi as my data. Just like I have no data at all. Here's why: At work I get zero service. None. But I can connect to wifi. However because I can't use my data at all none of my apps will work. Pandora, google play, YouTube, weather, netflix, you name it, all want to use data for the initial start of the app and I can't connect because I don't have service. So I need my phone and all my apps to use my wifi exclusively for everything while I'm at work. Simply turning data off doesn't work. I'm using a T-mobile Samsung Exhibit SGH-T759. Any help guys?
