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 live on Jules avenue in San Francisco, I have poor reception from MetroPCS. I think they're putting up some new towers in my area so hopefully it gets better.

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
