T-Mobile

1-3 bars but useless speeds all around the airport and surrounding neighborhoods. Pathetic

Very bad reception. Older 3G phone no longer working in this area, Purchased new iPhones using 4G LTE now, still very bad reception.

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

3-4 Bars Indoor. Sound good. Data good. Sprint is just fine over here.

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.
