My calls keep dropping. I located in North Dallas. I can barely make out any voice mails that are left--cuts in and out. I have an iPhone 6s and my husband has a galaxy edge. We are both having issues. We have a cell booster at home which I have re-set and we both reset our setting on our phones and on the booster. We got the booster several years ago and its worked find until recently. Any ideas? I dread going to the verizon store.
