A Verizon and Android upgrade were recently applied to phone. Now I have to have a wi-fi connection to send and receive email and to connect to the internet. With this upgrade extended features are at times unavailable when there is no available wi-fi connection to use.
That is not right, there is something wrong if wifi is required, are you sure data is enabled? If you swipe down from the top with 2 fingers you should get a bunch of icons, is Mobile Data turned on there?
