AT&T

Reasonable outdoor reception. Poor / Very poor indoor reception. AT&T tower is on Montara peak so the steep hill west of Seville is likely weakening signal.

Terrible coverage in downtown San Carlos. Shows 4 bars and LTE but will not load webpages or apps. Has gotten worse in past year?? Often have to switch to 3G

Have had Verizon for over 6 years. This last year started working in San Carlos. I have 4 bars but dropped calls all the time. I have LTE but can't load websites or check email. Seems like no carrier has their act together around here.

We bought a property from people who used ATT and said they could get cell reception often. We show as low as 1 bar sometimes but have never failed to get signal and usually get 3 and 4GLTE (Verizon style.)

Terrible! 1-bar. 2-bars occasionally. When I upgrade my iPhone I will be gone to Verizon. After all, this is the center of Silicon Valley! Also had to return AT&T microcell. It would not lock on poor AT&T signal.

Sprint sucks and the only reason they get service is because they roam and use verizons signal because they use the same cdma technology

Reception is awful here. I barely can make calls and if they get through the call drops within seconds. I can't even get 3g.
