Gizmo watch keeps dropping calls. It connects for 2 seconds and then drops the call. There is good Verizon coverage in the area and thus can't understand why it drops. THe dropped calls are also sporadic. Today, the Gizmo was able to connect a call for 2:58 minutes before it dropped. Then it dropped the next 2 calls in a row after 2 seconds. Last week, we just couldn't put a call through at all after trying 7 times in a row on different days. Why?
