I'm wondering if I have a defective device or if there are settings that need to be changed. My tablet disconnects from the network and shows "no service" although other Verizon wireless devices in the same room (phone, WiFi) show the Verizon network is available and they remain connected. I am still watching if there is a similar issue when connected to WiFi. I have had the device for two days. Is there a fix or should I return the device?
