Poor connectivity for T Mobile on Seaport Blvd.(in the business park). Some places in the parking lot have no connectivity at all.

Absolutely atrocious coverage and service from ATT. One block off El Camino in the middle of Silicon Valley, and virtually unusable phone service. All calls via WiFi or they don’t go at all. Been like this for years.

I have T-Mobile and get excellent coverage. 4G LTE speeds vary depending on location and time, but always fast enough to stream HD. Note: T-Mobile and MetroPCS or now called Metro by T-Mobile have the exact same coverage and speed. I drive a taxi and I rarely experience dead areas with the exception of south of Half Moon Bay, which every carrier is useless

No ATT Reception in Sea Haven, nor in downtown near the the middle school(!). Totally dead near Miramar. Neighbors say that ATT removed two towers. I filed a complaint with the FCC and ATT said the fine print in their contract says that they don't need to provide service in published coverage zones and they "understand" if I left.

I'd say the cell phone coverage feels like a third world nation but I happen to know that third world phone coverage is vastly superior. Have not completed a 10-minute call in months with multiple drops, re-dials. Thanks AT&T.

No coverage for months. Repeated calls and mark-the-spot app does nothing. They said that is a no tower area.
