Lately, I've been experiencing a high number of dropped calls. I have had this happen in the past, and the agent asked me to call (I believe) *52-but seeing as though I have forgotten the * code, I didn't want to do anything else to further jeopardize my service. But service has been getting worse lately with all the dropped calls, on 2 of 2 lines I have. And , sometimes, when I get through, (separate issue lately) either I can hear the other party good and they cant hear me or vice versa and yes, I have tried restarting the phones as I was told to do when I first brought this to Verizon's' attention; but that seems to be only a quick fix. Yesterday, during a conversation with my mother, the call was lost. I looked at the screen and it said no signal, then no sim, them 5 of 5 bars, all within seconds.
