I got a replacement phone three days ago, when I go to work I have a few bad spots in the plant where I lose signal completely. When this happened before, it would eventually kick on to either 1x or no signal but always come back up. Now w the replacement phone..... When I lose signal..... I have to deactivate the iPhone. I don't have wifi at work so I have to go til I get home in the morning or tether to a friends phone while I redo info to get it back up and running...... Any help would be great!!!! Going to a better verizon store in the morning I hope!!!
