Unable to access Verizon network! Got pop up window that "you've reached your mobile data usage limit. Mobile data turned off. " I have option to click re-enable button but doing so may result in additional charges. I've check settings, my mobile data box is checked. When I try to open a web page it tells me I'm off line with message "Wi-Fi and mobile data are turned off. The page can be loaded once you connect to a network. Error code: ERR_INTERNET_DISCONNECTED" My wi-fi DOES work, it's the Verizon network that I cannot access. Someone PLEASE HELP.
