User Reported Dead Zones In Costa Mesa

Carrier Address Comment Date Added
Verizon317 Robin Hood LnHorrible reception. Terrible sound quality. Constant dropped calls. Purchased a signal booster/extender for home from Verizon -- barely slightly better, and that's because the device ties into and uses bandwidth from our DSL! CLAIM:Verizon's map says this entire area is solid 4G reception. REALITY: I'm usually getting a couple bars of the 1X network, even with the extender.2016
Verizon425 Enclave CirBarely any service, bad reception. Verizon has mapped as 4G coverage, usually it's a bar or two of 3G or even 1x. Calls frequently dropped or garbled, even standing outside away from buildings.2019
Verizon444 Enclave CirNo 4G Signal, poor reception.2015
