I have been a verizon customer for 15+ years and rarely have trouble connecting to the network. However recently I moved to Santa Clarita, CA and frequently experience dead spots. This blackouts occur in Valencia and Saugus for my phone. Apps and texting are unusable in these areas as well as dropped calls mid conversation.
Below is a link to the communities thoughts on best cell coverage. As well as some specific locations such as target shopping plaza and Copperhill/Haskell.

Please take the time to increase coverage in the Santa Clarita Valley. Upwards of 200,000 people live here. I do not want to have to switch providers but I may have no choice to feel safe on the road and in these neighborhoods.
