1. They have been claiming they are building new towers for the last THREE years. 2. No coverage AT ALL in any bart tunnel 3. No coverage fully across the bay bridge 4. Spotty coverage in SOMA 5. Google hangouts is utterly useless on mobile 6. three huge dead zones on 880 between Oakland and Menlo park, no coverage across dumbarton, etc.
I wish companies would stop partnering with them for services like this.
I carry a verizon MIFI with me everywhere for work (ops) and I turn it on every time I get on bart - when I am in the car and when I am sitting around in any restaurant / coffee shop / bar for any time because the network sucks so bad.
