Which means you rely totally on wifi to use features like safari, mail, etc. I ask because if you have data off then what do you do to get basic features that require data? Specifically, I'm talking about voicemail notification which you can only get if you have data turned on. Being connected to wifi does not get you voicemail notification. *Note: I am not talking about getting the voicemail. I'm talking about being notified that you have a voicemail message. I'm also not talking about visual voicemail which requires data. I'm talking about just getting the red dot on the voicemail tab in the phone app that tells you that you have a voicemail. This happens on iOS 8.1 If you miss a call and that person leaves a message then you'll never know that you have a voicemail unless you just happen to check you voicemail, but by then it might be days or weeks since the person left you that message. Just wondering what you guys do or maybe you don't care to know whether someone left you a voicemail.
