Verizon5800 W Walden DrBefore a hail storm a few months back, we had poor reception in a small area around our house. Now it's much, much worse. Most days I have to stand outside to make a phone call, and frequently that doesn't even work - audio cuts in and out, or call drops completely. Incoming calls will go straight to voice mail without even registering as a missed call. Texting seems to work fine, though. It seems if I go 2-3 blocks in any direction, reception improves and calls go through just fine. It's a Samsung Galaxy 3 phone, so it' not like it's bad equipment.2014
