Who I have the same questioned this topic

Hi - I've noticed that coverage has progressively gotten worse and worse along Duboce Ave in zip code 94114. Specific location is four blocks centered around 37.769253, -122.432909 (lat/long).  It's been very bad for the past 3 months (mid April - present, mid July).  My phone which is a Motorola Moto X second generation.  It cycles between 3G, 4G and no signal and data performance is very poor (web pages sometimes load, sometimes do not load). I don't have any problems in other areas of San Francisco. @VZWSupport
