Sounds like the phone's hardware radio has gone bad. I had a phone do that once and had to get a replacement. Basically the phone's radio is not announcing itself to the network so the network has no way of knowing how to find you to send you phone calls and text. Once you make a phone call then you are announcing your location and you receive your txt messages at the time. Sounds strange but that is what i was told by a tech and flashing the ROM did not fix the issue but then again that was a Motorola phone. I'd suggest to do some research and try to flash it back to the original Verizon ROM to see if that helps at all if not then I'd say its a bad phone radio.
