Hi aroyal641. I'm happy to hear you've had such a wonderful few years with your LG phone. I checked for any reports of network issues in 91711 and it looks like a great area. Dialing *228 and choosing option 2 is a good update to your phone about once a month to keep the roaming information up to date. Have you tried rebooting the phone by pulling out the battery for a few seconds? Have you spoke with any other Verizon customers at home or school that are having trouble too? I know it's been a great run, but we may also need to start considering replacement vzw.com/phones options.
