I cannot call out or receive calls. When I try to call out, it dials and then radials and then hangs up. I cannot hear a dial tone either. I reset my phone and it did not solve the problem. I used backup asst. to get my contacts last night (112 contacts) and this morning I only had 7 contacts. What happened to those contacts. I’m at my wits end! Someone help, I can’t call Verizon, my phone won’t let me. My texts messaging is fine.
