Ok, so I have had my Samgsung Intercept through Virgin Mobile activated for almost a year now. Today, I try to call my boyfriend and the phone tells me "Signal Faded. Call is lost." I have minutes on my phone. I have 5 bars on my signal icon. I have tried taking the battery out and doing a factory reset. Now, I am able to call my father (the call goes through and I actually talk to him), but I can't call anyone else. I even tried selecting the activation icon on my phone and it says I have successfully activated my phone. I can send and recieve texts all day long. Can someone please help me with this? I love my phone, but I have never experienced so many problems in my entire life!
