My friend has a Verizon iPhone, i'm not sure which one, and his phone has been shut off due to nonpayment. When I wanted to facetime with him today, i told him to turn off cellular and turn on WiFi and facetime and the phone should essentially function as an iPod. He says its not working. Keeps connecting him to Verizon. Yet, he can go on fb. Does Verizon prevent facetime working if a bill hasn't been paid?
