My wife and I have had excellent coverage from Verizon in our home area of 93428 since 2011. Suddenly this morning both of our phones are searching for service. The phones will enter in and out of service area momentarily. I have completed the troubleshooting efforts of turning my phone on and off, removing battery and replacing it and checking for aircraft mode. No success. The phones were working during the night as we had a power outage in the area for several hours. Has a cell tower gone out of service in the area?? Please advise.
