How do I turn the carrier on my phone off?
Im trying to turn my carrier on the phone off so I can use my Apple ID and text other Iphones on the Imessage app. I have went in 'settings' and gone under 'cellular' and turned off 'cellular data' but the carrier (which is Sprint) still shows at the top of the screen next to the Wi-Fi. How can I Fix this so I can text?
iPhone 4, iOS 7.1.2
